Meet Ye-Eun Seo, a current Ph.D. student from the laboratory of Prof. Doil Choi in the Department of Horticultural Science and Biotechnology at Seoul National University, South Korea. Ye-Eun received the MPMI Best Student Paper Award for her first-author paper on "Phytophthora infestans RxLR Effector PITG06478 Hijacks 14-3-3 to Suppress PMA Activity Leading to Necrotrophic Cell Death." Her research focuses on molecular plant-microbe interactions, particularly examining the mechanisms by which pathogen effectors manipulate host cellular processes and how plants defend against these pathogens. Her recent work focused on elucidating the cell death mechanisms related to the plasma membrane proton pump in plants and on plant immune receptors and effectors from P. capsici and P. infestans. Currently, she is exploring the interactions between Solanaceae plants and P. capsici, with an emphasis on nonhost resistance mechanisms and the role of secreted proteins in pathogenicity. Through this research, she aims to contribute to expand our understanding of plant immunity and the development of sustainable crop protection strategies. To gain more insights into her research interests and scientific journey, and congratulate and celebrate her success, read this first-author interview.

1. What do you think is the most important or exciting finding from your paper?

In our paper, we investigated how the P. infestans RxLR effector PITG06478 induces cell death in Nicotiana benthamiana by targeting the plasma membrane H+-ATPase (PMA) activity and its interaction with 14-3-3 proteins. In my opinion, the most interesting finding from our paper is that fusicoccin treatment affected the association between 14-3-3 and the effector. Fusicoccin is an irreversible activator of PMA, so its application alters conditions within the plant cell—particularly the pH. This suggests that pH changes could influence the effector's mode of action, implying that pH is a critical factor in regulating effector-host interactions and cell death mechanisms.

2. Was there a piece of data that was particularly challenging to obtain or a part of the project that was particularly difficult?

Initially, we performed a screen to test whether fusicoccin treatment affected effector-induced cell death and found that cell death was affected in the presence of several effectors, but none of them interacted with PMA. This was contrary to our initial expectations, so we had to test an alternate approach. We then conducted another screen to test whether fusicoccin treatment changed subcellular localization of the effector. That's how we identified PITG06478 for further investigation. I think we were fortunate to be able to specify the effector's mode of action through these two screening methods and subsequent research. This experience taught me the importance of flexibility in research and the value of pursuing unexpected results. I came to understand that sometimes interesting findings can come from results that don't match our initial hypotheses and that being open to changing our approach can lead to new insights.

3. What research project are you most excited about right now?

Currently, I'm very excited about my work with P. capsici secreted proteins. These proteins have the potential to act as PAMPs (pathogen-associated molecular patterns) or apoplastic effectors in plant cells. I've identified candidates that can induce cell death in plants, and now I'm focusing on uncovering their receptors and downstream signaling pathways. I believe this research could lead to interesting findings and potentially uncover novel mechanisms in plant-pathogen interactions.

4. What drew you to your current lab?

I first met my current advisor during my first major course after declaring my major as an undergraduate. What really impressed me was that in every class, the professor introduced fascinating new cutting-edge research papers. This approach not only made the classes more engaging but also gave us insight into the latest developments in the field. I found the professor's research area incredibly interesting, and it aligned well with my own scientific interests. The professor's enthusiasm for the subject and dedication to keeping students updated with the most recent advancements in the field really drew me to this lab. As an undergraduate research assistant in this lab, I had an eye-opening experience. I enjoyed applying the experimental techniques I learned in class to real research situations. The process of conducting experiments was genuinely interesting, even when faced with challenges. I found the troubleshooting process, where we discussed failed experiments with other researchers, particularly enriching. These discussions not only helped solve immediate problems but also deepened my understanding of the scientific process. Through this hands-on experience, I discovered that I was truly fascinated by the process of conducting experiments and doing research.

5. How did you choose to join your current graduate program?

I chose to join my current graduate program in Horticultural Biotechnology because of my experience as an undergraduate research assistant in the lab of Prof. Doil Choi. Our lab focuses on molecular plant-microbe interactions in horticultural crops. During my time as an undergraduate researcher, I became fascinated with the molecular plant-microbe interactions field. This interest, combined with the positive experiences I had in the lab, led me to pursue graduate studies in the same department and lab. I wanted to continue working on molecular plant-microbe interactions in horticultural crops, so joining the Horticultural Biotechnology graduate program was a natural choice for me.

6. What advice would you give to starting graduate students?

As a fellow graduate student still learning and growing, I'd like to share some advice from my experiences so far. I've found that asking questions and seeking clarification from advisors, professors, and peers has been incredibly helpful. Staying curious and exploring various resources, as well as keeping up with recent research, has also been beneficial. I've noticed that keeping organized notes and documenting experiments and ideas helps me track my progress and thoughts. When possible, I try to attend conferences and seminars, which I've found to be great learning opportunities, though I'm still working on my networking skills. I'm also trying to view constructive criticism as a chance to improve my work and be open to feedback. These are just my personal experiences, and I'm sure every graduate student's journey is unique.

7. Who has inspired you scientifically? Why?

The most scientifically inspiring people to me are my PI and lab members. Our weekly group lab meetings are particularly valuable. During these discussions, my professor often provides guidance from a broader perspective, offering insights that help shape our research directions. My lab mates also contribute ideas, sharing their thoughts on experiments and project approaches. These interactions have shown me the importance of collaborative thinking in science. Sometimes, discussions with lab mates have led me to consider new methods or help refine the direction of my project. I learn a lot from their experiences and approaches. Additionally, I find seminars and research papers from other scientists in our field to be informative and motivating. Seeing the work being done by researchers worldwide encourages me to continue developing my skills and knowledge in my own studies.

8. How can people find you on social media?

I have an X account, @YEEUNSEOYEEUN (although I'm not very active in posting…).

9. Is there anything else you would like to share? If so, what is it?

I'd like to take this opportunity to express my sincere gratitude to my professor, Dr. Doil Choi, and my lab members. I'm truly thankful for their guidance, support, and collaboration throughout my research journey.

Honorable Mentions for Best Student Paper in MPMI: Jess Choi

KEK on 12/20/2024 2:42 PM

Jiyeong (Jess) Choi is a recent Ph.D. degree graduate from Dr. Marc Fuchs' lab at Cornell University, USA. Jess defended her Ph.D. dissertation in August and is currently working as a research assistant in the Fuchs lab.

1. What do you think is the most important or exciting finding from your paper?

This study identified three viral suppressors of RNA silencing (VSRs) encoded by grapevine fanleaf virus (GFLV): proteins 1A and 1B and the fusion protein 1AB, which is an intermediary product of polyprotein proteolytic cleavage processing. One of the most thrilling findings of this study is that the two independent GFLV VSRs (1A and 1B) can function either individually (1A and 1B) or as the fused form (1AB) to reverse systemic RNA silencing and differentially alter host genes associated with antiviral RNA silencing, suggesting that GFLV employs multiple strategies to evade host antiviral defense. This finding assigns a function to protein 1A for the first time and provides the first experimentally validated function for protein 1B. Overall, this study deepened our knowledge of how GFLV counters host antiviral immunity and contributes valuable insights into the molecular biology of this virus.

2. Was there a piece of data that was particularly challenging to obtain or a part of the project that was particularly difficult?

The most challenging aspect of the project was assessing and validating RNA silencing suppression functions of GFLV proteins 1A, 1B, and 1AB. I executed three distinct RNA silencing suppression assays to evaluate their suppression abilities from multiple perspectives and approaches. Designing, developing, optimizing, and conducting these assays were difficult due to the unique RNA silencing suppression characteristics and host gene modulation abilities specific to each protein. By analyzing results both individually and collectively, I validated RNA silencing suppression functions of GFLV proteins 1A, 1B, and 1AB, identifying them as GFLV VSRs.

3. What research project are you most excited about right now?

I'm currently working on elucidating subcellular localization of GFLV VSRs in planta using live-cell imaging techniques via confocal microscopy. Building on the identification of GFLV VSRs (Choi et al., 2023), I have recently identified specific amino acid residues that are critical for systemic RNA silencing suppression functions of GFLV VSRs (Choi et al., 2024). Drawing on these findings, I will explore whether the specific subcellular localization of GFLV VSRs is required for their suppression functions. This study will facilitate identifying potential host interactants of GFLV VSRs at the level of specific organelles, providing further insights into the RNA silencing suppression mechanisms utilized by GFLV VSRs.

4. What drew you to your current lab?

During my undergraduate studies, I completed a 9-week research internship in Dr. Marc Fuchs' research lab through the Summer Research Scholar Program at Cornell AgriTech. I specifically applied to his plant virology program because I was fascinated by how viruses, primarily composed of proteins and nucleic acids (and sometimes lipids), can overcome the defense mechanisms of complex eukaryotic organisms to cause devastating diseases. I developed a specific interest in studying plant viruses because the impact of plant viral diseases extends beyond the host, affecting both the economy and food security. My summer research focused on elucidating the vein-clearing symptom determinants of GFLV under the mentorship of Dr. Larissa Osterbaan (published in MPMI; Osterbaan et al., 2018). This experience sparked my interest in studying molecular biology of GFLV and deepened my passion for plant molecular virology.

5. What advice would you give to starting graduate students?

When you encounter unexpected data, don't focus on what you might have done "wrong." Instead, shift your mindset to what you can do "next" and how you can leverage that unexpected data to build on your research.

6. Who has inspired you scientifically? Why?

I am inspired by Dr. Barbara McClintock for her transformative contributions to genetics, particularly her discovery of transposable elements in maize, which reshaped our understanding of gene regulation. Her innovative thinking inspires me to think outside the box in my research. I admire her resilience and determination in overcoming adversity in a historically male-dominated field, which continues to inspire women in science today. Dr. McClintock's legacy encourages me to pursue my scientific and career goals with courage and creativity.

7. Have you been involved in other scientific/professional development activities? And how have these contributed to your training?

I served as a secretary for the Bioengineering Applications Committee of The American Phytopathological Society (APS). I co-organized the APS "Exploring Career Paths in Biotechnology" webinar in 2023, which focused on introducing diverse career opportunities in the field of biotechnology to students and postdocs by featuring biotechnologists from academia, government, Extension, and industry. This role allowed me to develop valuable organizational and communication skills, network with diverse experts in the biotechnology and bioengineering fields, and gain insightful perspectives in diverse biotechnology career opportunities.

Additionally, I co-organized a plant pathology workshop, "Somebody Call the Plant Doctor," for Expanding Your Horizons at Cornell in 2022. This workshop focused on providing hands-on learning experiences for seventh- to nineth-grade students in plant pathology, teaching them how to identify symptoms of plant diseases, use identification sheets and microscopes, and understand how to prevent the spread of pathogens. Through this experience, I was able to practice and improve my public speaking and science communication skills.

8. What is the greatest challenge you have encountered in your career? What did you do to overcome this challenge?

The greatest challenge I faced during my graduate career was a lack of confidence in writing. Initially, I often felt lost, unsure of where to begin, pause, or conclude. Drafting manuscripts made me anxious, but the repetitive process of drafting, editing, and redrafting gradually helped me become more comfortable with my writing. Committing to publish my research and reading a wide range of articles enhanced my understanding of scientific communication and contributed to my growing confidence.

9. How can people find you on social media?

People can find me on X (@jesspatho36), LinkedIn (jess-choi-71b4b5225) ,or ResearchGate (Jiyeong-Choi-3).

10. Is there anything else you would like to share? If so, what is it?

I am very grateful for the opportunity to publish my work in MPMI. I would like to thank Drs. Ved Prakash and Anjali Iyer-Pascuzzi for their invitation to complete this interview and their contributions to MPMI.

11. Bonus question: What's your favorite pathogen or disease?

Tulip breaking virus! It is the first plant virus I learned about, and it is also my mom's favorite plant pathogen!

Meet Graduate Student Suchismita "Suchi" Ghosh

KEK on 9/18/2024 5:56 PM

Meenu Singla-Rastogi, Innes Lab, Indiana University Bloomington, Bloomington, IN, USA

Meet graduate student Suchismita "Suchi" Ghosh from the Innes lab at Indiana University Bloomington, Bloomington, IN, USA. Suchi's very first first-author paper on the secretion of plant extracellular vesicles in response to compatible and incompatible fungal infections on alfalfa species was recently published in MPMI. In this Interactions spotlight, she provides insights into her deep-rooted passion for studying plant pathogens and how she navigated through the lows and highs during her graduate studies. Now that she has graduated, we congratulate her and wish her the best in her future endeavors.

1. What do you think is the most important or exciting finding from your paper?

Our paper is the first study that demonstrates a plant-fungal interaction interface in the three-dimensional space. Perhaps the most fascinating discovery is the presence of paramural bodies (PMBs) that are observed with a nonhost fungal pathogen infection in the plant cell and the corresponding increase in extracellular vesicles (EVs) isolated from nonhost infected plants. We could see the shape, and size, and evaluate the number of PMBs throughout the volume of the plant cell and reconstruct the images as 3D models. The images developed in this study provide us with a map to explore the insides of a plant cell during infection with its fungal pathogen, and thus, it is a first-of-its-kind study.

2. Was there a piece of data that was particularly challenging to obtain or a part of the project that was particularly difficult?

The most challenging data to obtain was a high enough resolution to visualize the contents inside the PMBs. These PMBs are extremely small, roughly 1 µm or less in diameter, and the vesicles inside them are even smaller. Using volume scope SEM was challenging in itself, but visualizing the vesicles inside PMBs seemed impossible. We then used focused ion beam scanning electron microscopy (FIB-SEM) for that purpose, and what seemed particularly challenging was to optimize the preparation of sample blocks and image them using FIB-SEM.

3. What research project are you most excited about right now?

Currently, I am working on characterizing different populations of plant EVs. Our paper revealed that plant cells secreted more vesicles when infected with their host and nonhost fungal pathogens. This raises the question of whether plants secrete a special class of defense-related vesicles in response to pathogen attack? In my current project, I intend to answer this question and identify distinct vesicle protein markers that mark different vesicle populations. This research will allow us to identify new mechanisms deployed by plants to fight their pathogens and open novel and exciting research areas in the field of plant-pathogen interaction.

4. What drew you to your current lab?

I have always been fascinated by plant-pathogen interactions. My family members in India were farmers for several generations, and we mostly grow our own vegetables in our garden and land. As a child, I was fascinated with plant diseases and made observations on our farmland, like black or red spots on leaves, vegetables, and fruits. When I got my undergraduate degree in biotechnology, I researched more about plant immunity and how disease management of crop plants helps millions of people across the world. This made me want to join Dr. Roger Innes' lab at Indiana University Bloomington, as he is one of the leading plant immunity researchers. Roger had a website that shared a story about his passion for studying plant diseases to better manage them. I realized we have similar passions, and I decided to try my luck and travel halfway across the world to pursue my graduate studies.

5. (For graduate students) How did you choose to join your current graduate program?

The most important criteria for me were the work of the professor and the diversity within the university. Grad school is a marathon that is impossible without a community. I knew Indiana University has great plant scientists and an amazing Indian and international student community. I also emailed the professors I was interested in working with before applying to grad school, and how they responded (if they did) factored into my choice for grad school. I strongly believe that finding the right fit is one of the most important determinants of success in grad school.

6. What advice would you give to starting graduate students?

Always talk to your advisor and lay out your expectations before starting grad school. Do not be scared to ask questions. I asked my professor about his mentoring philosophy and how he dealt with low morale in grad students. It is important to also build a community outside grad school. I had hiking and fishing buddies in grad school, and they were an integral part of my life during those years.

7. Who has inspired you scientifically? Why?

As a child, I was profoundly influenced by Sir Jagadish Chandra Bose. He is a Bengali, just like me, and an exceptional botanist and physicist. I was always interested in mathematics and plants, the two fields with minimum overlap. I graduated from the same undergraduate college in India as Dr. Bose and went on to his institute to do my master's research in plant immunity. I knew I wanted to study plants, and reading about his journey inspired me to follow my passion.

8. Have you been involved in other scientific/professional development activities? And, how have these contributed to your training?

I have been part of ASPB and IS-MPMI from the very beginning of grad school. It has helped me broaden my scientific network and attend conferences. I have gained tremendous insights on new technologies and works and formed collaborations from attending these conferences. I have also been able to make some industry connections by applying for industry-based conference travel awards. It was a great opportunity to explore outside of academia.

Besides academia, I love doing outreach with young kids. I taught an after-school math club for elementary students grades 3 to 6. I also volunteered for Science Olympiad training for middle school kids. These activities helped me keep my mind off grad school stress and give back to the community.

In grad school, I was part of the international student committee and my department's student committee. These programs have helped me form communities and friendships and develop leadership skills.

9. What is the greatest challenge you have encountered in your career? What did you do to overcome this challenge?

I had the misfortune of being a grad student in my early years when the global COVID-19 pandemic hit. It was a really hard time for me mentally. I was an international student, living alone, and socially distanced, with no family support here in the United States. I also lost a few family members back home due to COVID-19. All these conditions led to a lot of mental health problems, like depression and anxiety. It was hampering my productivity in the lab and my social life. Luckily, I had a lot of support from my PI, Dr. Roger Innes, and my lab members. I also underwent therapy and slowly worked through my issues. I took it one day at a time in the lab and found my ground back again.

10. How can people find you on social media?

11. Is there anything else you would like to share? If so, what is it?

Check out another paper from the Innes lab, "Three-Dimensional Ultrastructure of Arabidopsis Cotyledons Infected with Colletotrichum higginsianum," by former postdoc Dr. Kamesh Regmi. I am honored to be a part of this paper. This paper has some beautiful SEM images that delineate the cytological changes in Arabidopsis cotyledon upon fungal infection and represent them three-dimensionally.

Research Highlight: Evolution of the ToxB gene in Pyrenophora tritici-repentis and related species

KEK on 12/18/2023 12:34 PM

Reem Aboukhaddour, Cereal Pathology Lab, Agriculture and Agri-Food Canada, Lethbridge, AB, Canada

Overall Background

Across the expansive Canadian prairies, wheat can stretch as far as the eye can see, and during the growing season, its green leaves are a food source to several foliar-infecting pathogens. Among these pathogens is the fungus Pyrenophora tritici-repentis, which causes tan spot of wheat, a destructive foliar disease that emerged as a specialized necrotroph about 50 years ago. Since its emergence as a wheat pathogen, it has caused significant losses in North America, Australia, and other parts of the world. Today, tan spot is still one of the most destructive foliar diseases of wheat, and it is mainly managed by fungicides applications.

Why This Work and How It Came to Be

The question of how this fungus became a pathogen has been a pivotal inquiry among the research community, including my team, and aligns well with the ongoing exploration of the emergence of necrotrophic diseases. Since 2016, my lab has concentrated on wheat diseases, resulting in this paper as part of our overall studies. I have actively engaged with inquiries from students and scientists globally, providing guidance on accurately identifying the tan spot fungus and troubleshooting various aspects of working with the system. Some interactions were driven by my interest in tracing the pathogen's identification as a wheat pathogen in Japan in 1928, seeking old isolates, well characterized at the University of Manitoba and collected by my late Ph.D. supervisor, Dr. Lamari, who dedicated his research to establishing the tan spot-wheat interaction as a model system. These isolates, collected along the silk road, hold significant value for comparative genomic studies to trace the pathogen's evolution. Chance encounters with collaborators at conferences and meetings have further contributed to the establishment of a collaborative network spanning North and South America, North Africa, Europe, Japan, and Australia.

What began as a simple quest to single-spore the pathogen and conduct its proper characterization, though laborious and time-consuming, resulted in a substantial collection of isolates from diverse global locations and hosts and covering an interesting time scale. The increasing affordability of full genome sequencing, coupled with COVID-19 restrictions, prompted a shift in focus. Collaborating with experts, including Dr. Megan McDonald from the University of Birmingham in the United Kingdom, we released the pathogen's pangenome, chromosomal structural organization, and the reorganization of its effector-encoding genes and surrounding regions (Gourlie et al., 2022). Simultaneously, we explored the allelic diversity of effector-encoding genes in a broader collection of wheat leaf-spotting pathogens, with a specific emphasis on the ToxA gene, a key virulence determinant in North America and Australia (Aboukhaddour et al., 2023). Our research extended beyond the tan spot pathogen to encompass related species.

Simultaneously, our investigation of P. tritici-repentis virulence in North Africa (Kamel et al., 2019) revealed a prevalent ToxB effector in the pathogen populations. The ToxB gene, relatively understudied due to limited access in North American and Australian labs, presented an intriguing aspect for exploring virulence evolution in the fungal genome given its multicopy nature. Tan spot, increasingly concerning in North Africa and neighboring regions where ToxB is widespread, contrasts with North America, where ToxB is nearly absent; instead, a nonfunctional homolog prevails in certain pathogen races infecting durum wheat or recovered from grasses. A few years ago, we accidentally discovered that ToxB-producing isolates induce mild chlorosis in specific barley genotypes. Identifying a dominant single locus responsible for conferring sensitivity to ToxB-producing isolates in barley, a secondary host for the pathogen, added an interest to explore further the ToxB evolution (Aboukhaddour and Strelkov, 2016; Wei et al, 2020).

Considering these findings, the research highlighted here by Hafez et al. delves into the diversity and evolution of ToxB in tan spot pathogens and related species. This work complements our broader investigation into the evolutionary puzzle of tan spot virulence, shedding light on the sudden emergence of this wheat pathogen. The paper provides the research community with a more comprehensive understanding of the diversity of the ToxB gene and its homologs and access to valuable information from a large global collection that would otherwise be challenging to obtain. Ongoing research, in collaboration with Dr. McDonald, aims to decipher the mechanism of virulence gene duplications in the fungal genome. Armed with a wealth of well-studied isolates and continually expanding resources, this endeavor feels like a generational effort booming into an international collaboration to decode the emergence of this wheat pathogen.

Review Highlight: Molecular Mechanisms of Pseudomonas Assisted Plant Nitrogen Uptake—Opportunities for Modern Agriculture

KEK on 6/28/2023 3:23 PM

Borjana Arsova, Root Dynamics group, IBG 2- Plant sciences, Research center Julich, Julich, Germany

Full disclosure: when as plant scientists our group started using microbes as a means to improve plant performance, I thought of them as a "means to an end." Now I know this is naïve.

The Root Dynamics group in the Plant Sciences Institute in the Research Center in Jülich (IBG-2), Germany, mostly focuses on the plant response to beneficial microbes, and how plants adjust their metabolic pathways under suboptimal (nutrient) conditions, with and without these beneficial organisms. We observe that the nature of the interaction changes depending on the complex environment in which plants and microbes interact. We showed this, for example, in Kuang et al. (2022, Journal of Experimental Botany) and brought it into focus during the work presented here.

Conceptual figure of shared nitrogen biochemistry and transport across root and bacterial cells in the rhizosphere (Sanow et al., 2023; Fig. 3). Bacterial processes that impact plant N content. The left side represents plants growing with limited N, resulting in a decreased aerial biomass and increased root growth, whereas the right side represents potential plant growth-promoting mechanisms by Pseudomonas species that increase the aerial biomass under the same limited N conditions. Ammonium (NH₄⁺) and nitrate (NO₃^–) are taken up by the plant via dedicated transporters of the AMT and NRT families, respectively (left side, Bock and Wagner, 2001; Daims et al., 2015). PGPB increase availability of inorganic N to plants through the following mechanisms: (i) ammonification of organic N by P. psychrotolerans (Kang et al., 2020); (ii) P. stutzeri upregulating nif genes in A. brasilense via DAPG, resulting in the conversion of N₂ into NH₄⁺ (BNF) (Day et al., 2001; Combes-Meynet et al., 2011); and (iii) production and release of NH₄⁺ by P. fluorescens (Zhang et al., 2012). Dashed lines indicate reactions from or to the bacterium that occur based on the concentration of each reaction product in the respective space and the pH of the environment.

The use of a particular Pseudomonas strain in our lab happened by chance. A colleague sent us a sample, which was supposed to be a Sinorhizobium sp. Their lab had indications of growth promotion, but the project had stopped for various reasons. We also found plant growth-promotion ability, but the phenotype of our plants differed from the preliminary results of our colleagues. The sequencing results showed this to be a Pseudomonas strain. However, the phenotype was interesting, and our Ph.D. student Stefan Sanow was getting promising results in plants grown under low-nitrogen conditions, so he kept working with the new bacterium. This led to the initial question: Are the known molecular mechanisms in plant–bacteria interactions general for all bacteria, or can they be subdivided for specific phylogenetic groups?

Thus, Sanow started compiling evidence about known processes relevant to the Pseudomonadaceae. We found that there are many indications of horizontal gene transfer, which can clearly be linked between different bacterial groups. At the same time there are some differences that seem to be genera specific. The review by Sanow et al. (2023) published in MPMI is the result of this work. We think that this is a novel perspective on this complex genus that could set an example for understanding other genera as well.

The team behind this review comes from three continents—Europe, Australia, and Asia—and, in addition to the research center in Jülich, includes the University of Bonn (Germany), the University of Melbourne (Australia), Australian National University (Australia), and Hunan University of Arts and Science (China).
