University of California-Davis distinguished professor and IS-MPMI member Dr. Pam Ronald has been awarded the 2022 International Wolf Prize in Agriculture "for pioneering work on disease resistance and environmental stress tolerance in rice." The Wolf Prize is awarded for achievements in the interest of humankind and friendly relations among people.
 
Pyrenophora tritici-repentis causes tan spot, an important foliar disease of wheat worldwide. This fungal pathogen produces three necrotrophic effectors (Ptr ToxA, Ptr ToxB, and Ptr ToxC) to induce necrosis or chlorosis in wheat. Here, Gongjun Shi and colleagues report the genetic mapping, molecular cloning, and functional analysis of the fungal gene (ToxC1) required for Ptr ToxC production.
 
Senior graduate students and postdoctoral scholars are encouraged to present their MPMI research at the new Early Career Showcase. The showcase will take place online June 8–9 and September 20–21 and is free to all IS-MPMI members. Nominate yourself, a colleague, or a student before March 31.

A Letter from IS-MPMI President Mary Beth Mudgett

I hope this newsletter finds everyone healthy and that their semester is off to a great start.

Our IS-MPMI community has proven to be remarkably resilient during these turbulent times. The launch of several new society initiatives has been instrumental in keeping us connected and enabling us to share our exciting research from afar. Kudos to MPMI Editor-in-Chief Jeanne Harris and her team for hosting the monthly What's New in MPMI Virtual Seminar series highlighting research advances published in the MPMI journal. These free events have been instrumental in engaging colleagues working on plant–microbe interactions, both society members and nonmembers, from 61 countries.

We have also received enthusiastic feedback on the eSymposia series and Translational Science Workshops held in 2021. Many thanks to the organizers, speakers, and moderators for their contributions. Moving forward, we aim to offer additional online events, especially during non-congress years. I encourage you to submit your suggestions for new research themes to cover in the near future. Feel free to write to me.

Unfortunately, we had to cancel the 2022 IS-MPMI Congress planned for JeJu, Korea, due to the uncertainty of COVID-19 impacting the safety of our community. We are so grateful to the entire local organizing committee, led by Professors Doil Choi, Keehoon Sohn, and Ho Won Jung and the Korean Society for Plant Pathology, for their extraordinary efforts to plan a congress during a pandemic. We hope to hold a meeting in Korea in the coming years.

Our inability to gather in-person as a society again this year has greatly impacted our junior colleagues and their professional development. To address this, IS-MPMI will be hosting two half-day virtual symposia to highlight the work of early-career researchers. The dates are June 8 and 9 and September 20 and 21, 2022. More details about the 2022 Early Career Showcase can be found here. Please nominate your colleagues! The deadline is March 31. We will follow up with a speaker program very soon. This event is free to society members.

I am hopeful that 2023 will allow us to meet in-person. Be sure to mark your calendars for July 16–20, 2023, to join us for our 2023 IS-MPMI Congress in Providence, RI, USA. Roger Innes will take the helm of our society in July 2022 as president and is leading efforts to organize a stimulating meeting program.

In closing, I would like to send peaceful wishes and support to our colleagues around the world, especially those who are impacted by the Russian-Ukrainian conflict. Our academic and research missions play important and long-lasting roles in the vitality of our global society.​

Wishing you all the best,

Mary Beth Mudgett

President, IS-MPMI

InterStellar: Dr. Pam Ronald Awarded the International Wolf Prize in Agriculture

University of California-Davis and IS-MPMI member Dr. Pam Ronald has been awarded the 2022 International Wolf Prize in Agriculture "for pioneering work on disease resistance and environmental stress tolerance in rice." The Wolf Prize is awarded annually to scientists and artists for their achievements in the interest of humankind and friendly relations among people. Dr. Ronald is a distinguished professor in the UC Davis Department of Plant Pathology, having joined the faculty in 1992. She is also affiliated with the UC Davis Genome Center, the Innovative Genomics Institute, and the Physical Biosciences Division at Lawrence Berkeley National Laboratory. Dr. Ronald is the first woman among six UC Davis scientists to receive the award, and she joins Dr. Ilan Chet (1998) as IS-MPMI members who have been awarded this prestigious prize. About a year ago, Dr. Ronald was awarded the World Agriculture Prize, and you can read about her accomplishments and insights in an InterStellar interview led by Nick Colaianni published in Interactions in December 2021.

InterConnections: Get to Know Gongjun Shi

​A Conserved Hypothetic​al Gene Is Required but Not Sufficient for Ptr ToxC Production in Pyrenophora tritici-repentis​


Name
Gongjun Shi

Current Position: Research Specialist, Department of Plant Pathology, North Dakota State University, ND, USA

Education: Ph.D. degree in genomics and bioinformatics at North Dakota State University, USA; Ph.D. and M.S. degrees in olericulture at Nanjing Agricultural University, China; and B.S. degree, with honors, in olericulture at Shandong Agricultural University, China

Nonscientific Interests: Hiking, running, photography, cooking, and volunteering

Brief Bio: I was born in a small village in Shandong Province, China, and had a dream to be a medical doctor one day. However, I was not accepted into medical school, which led me to pursue degrees in olericulture and then genomics and bioinformatics. Now, I am proud to be a plant pathologist. During my years working with Brassica, I was fascinated with the sophisticated mechanisms by which plants fertilize at the molecular level. How plants recognize self and non-self pollen particularly drew my attention. Joining the Key Lab of Southern Vegetable Crop Genetic Improvement led by Dr. Xilin Hou allowed me to pursue this project. At the same time, how plants distinguish self and non-self molecules captured my eye for understanding how plants can effectively balance energy for both growth and defense processes.

After enrolling in the Department of Plant Pathology at North Dakota State University, I worked in Dr. Justin Faris' lab and focused on the cloning of wheat sensitivity genes interacting with necrotrophic effectors produced by Parastagnospora nodorum. Collaborating with Dr. Tim Friesen's group, we found that necrotrophic specialists could hijack both PAMP-triggered immunity and the effector-triggered immunity pathway to cause disease. As a postdoc, I entered Dr. Daniel Kliebenstein's lab at the University of California, Davis, to work on a necrotrophic generalist, Botrytis cinerea, to understand its virulence across the plant kingdom. Currently, I am working on wheat tan spot disease and bacteria leaf streak research led by Dr. Zhaohui Liu. I continue to leverage my plant breeding background, together with my expertise in plant pathology, to unveil many more exciting stories of phytopathogens and plant immunity.​
