Call for Papers! Publish in the MPMI Focus Issue on Fine Grain

Despite recent advances in molecular tools and genome sequencing, cereal crop diseases remain a significant challenge to global food security. Yield losses each year from fungi, bacteria, oomycete, viruses, and nematodes need substantial economic investment and impact the world's poorest populations disproportionately. Climate change exacerbates the problem, altering pathogen ranges, allowing the spread of existing plant diseases into new growing areas while facilitating the emergence of new pathogenic strains. Global trade compounds the challenge of pathogen spread. Thus, there is a pressing need for a detailed understanding of the biology of cereal crop diseases, with an expectation that this will identify plant strengths and weaknesses that can be exploited to safeguard grain sources.

In this MPMI Focus Issue, we seek to draw together, through reviews and original research papers, the contemporary developments in understanding staple cereal crops and their pathogens. We encourage papers focused on pathogen, host biology, or both. Investigations should be at the molecular, cellular, and/or genomic level and may include studies of effector function and evolution, plant receptors, and pathogen physiology, as well as signal transduction. Both the topic and pathosystem of study are intended to be broad in order to best capture this important field of study. Our goal is that this issue will highlight potential solutions and significant breakthroughs in cereal crop disease research, as well as identify important knowledge gaps, that will guide future studies and ultimately foster the implementation of meaningful management practices.

Focus Issue Editors Lida Derevnina, Ksenia Krasileva, Benjamin Schwessinger, and Richard Wilson look forward to receiving your manuscripts addressing this globally important research area.

Submission Deadline: September 30, 2024

Read the Latest MPMI Editor's Pick

Phytophthora sojae Effector PsCRN108 Targets CAMTA2 to Suppress HSP40 Expression and ROS Burst

Zitong Yang, Gan Ai, Xinyu Lu, Yuke Li, Jinlu Miao, Wen Song, Heng Xu, Jinding Liu, Danyu Shen, and Daolong Dou 

Yang et al. show how the Phytophthora sojae effector PsCRN108 suppresses plant immunity by inhibiting the expression of Heat Shock Protein (HSP) family genes, including NbHSP40, through interaction with NbCAMTA2, a negative regulator of plant immunity, shedding light on a new mechanism by which CRN effectors manipulate transcription factors to impact immunity.

What Does It Mean to Practice Inclusion in Science?

I realized the world is mine. I can do whatever I want. But I still experience intimidation and fear being in a scientific field because communication is not accessible in that context. And so, I was deciding whether I should pursue my education in biochemistry or in another field, and someone said to me, 'Go forth with your education in whatever field you want.'

—Dr. Amie Fornah Sankoh

In a new episode of Microgreens, the MPMI journal podcast, Dr. Tiff Mak and Dr. Dominique Holtappels interview Dr. Amie Fornah Sankoh, who highlights the importance of mentorship and disability justice in science. Amie shares her journey to becoming the first deaf, black woman to receive a doctorate in a STEM (science, technology, engineering, and math) discipline in the United States.

A full transcript to the audio recording of the interview can be found here. A video version of the recording will be released later for audiences to experience and engage with Amie through sign language.​

Introducing the H. H. Flor Distinguished Review in MPMI

Timothy L. Friesen, Editor-in-Chief Molecular Plant–Microbe Interactions

For each gene that conditions reaction in the host there is a corresponding gene in the parasite that conditions pathogenicity.

In these words, Harold H. Flor summed up his gene-for-gene concept in his 1971 Annual Review of Phytopathology article (Flor 1971). Flor's gene-for-gene concept provided a new framework for how we think about plant–microbe interactions. Harold H. Flor was born May 27, 1900. He obtained a B.S. degree in agriculture in 1922, an M.S. degree working on covered smuts of small grains in 1924 and was granted a Ph.D. degree for his work on root rot complex of sugar cane in 1929—all three degrees from the University of Minnesota. Dr. Flor then took a position with the U.S. Department of Agriculture in Pullman, WA, where he worked on wheat bunt. In 1931, he moved to Fargo, ND, to take a position with the USDA on the North Dakota State University campus, where he was tasked with studying diseases of flax. It was during his time with the USDA in Fargo that he performed his landmark research on the flax–flax rust interaction, which ultimately was used to define the gene-for-gene hypothesis that became so prevalent in describing many host–pathogen interactions. The gene-for-gene concept still stands as one of the most significant contributions to plant pathology and was established long before modern molecular biology or even a complete understanding of genetic material or protein–protein interactions.

Based on the landmark research performed by Dr. Flor, it was an obvious choice to use his name to help define what this distinguished review category is all about. An H.H. Flor Distinguished Review is a review written by visionary scientists who have also changed the way we think about an area of molecular plant–microbe interactions. These distinguished reviews will ultimately include all categories of plant–microbe interactions from pathogenic to symbiotic interactions. It is our intent to invite leaders in the MPMI field to write authoritative reviews that provide not only a historical perspective but also to provide a vision for where their respective fields are moving, ultimately providing a valuable resource to the MPMI community.

In the August issue of Molecular Plant–Microbe Interactions, the first of the H.H. Flor Distinguished Reviews will be published, including "From Gene-for-Gene to Resistosomes: Flor's Enduring Legacy," written by Peter N. Dodds and "New Biochemical Principles for NLR Immunity in Plants," written by Jijie Chai, Wen Song, and Jane E. Parker.
