| 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.

 Effectors are central to determining the complex and dynamic interaction between plants and microbes. Whether those interactions result in the establishment of a beneficial or negative interaction, effectors are at the interface of any plant–microbe interaction. Despite their role as mediators of plant–microbe interactions, gaining a full understanding of the biology and evolution of these intriguing molecules has been a challenging task. This
MPMI Focus Issue will present the latest developments in the study of microbial effector biology and evolution in the context of plant immunity across diverse systems. As the scientific community seeks to respond to global challenges in agriculture and food production, we wish to highlight potential solutions and technologies emerging from research in microbial effectors. We invite research and review articles that explore the complex role of effectors in molecular plant–microbe interactions. Articles highlighting translational research, as well as fundamental understanding, are welcome. We look forward to assembling an issue that features the excellent research in this area! Benefits to AuthorsA Focus Issue offers authors several benefits. A single-topic issue gives scientists an opportunity to publish alongside the related work of their peers to highlight progress in a focal area. The Effectors at the Interface of Plant–Microbe Interactions
MPMI Focus Issue will be widely promoted and is expected to be highly cited, giving authors maximum exposure. Articles will be submitted to Crossref, allowing citation tracking and connectivity as this research area moves forward in
MPMI and other scientific journals. If you are working on research described herein, submit your manuscript to
MPMI and select "Focus Issue" as the article type. Please also indicate in your cover letter that you would like your manuscript to be considered for the 2024 Focus Issue. For more information about the scope of this issue, please contact

MPMI proudly presents a
special focus issue addressing the
#2 top unanswered research question identified by the
MPMI scientific community: How do aspects of the abiotic environment affect plant–microbe interactions, and conversely, how do plant–microbe interactions affect host response to abiotic stress? The science presented is crucial to understanding how climate change affects plants on a microbial level and to protecting plant health.

As our climate changes, the rapidity of the changes in temperature and carbon dioxide levels and the many planetary processes that they affect, altering weather patterns and soil salinity among others, make it imperative for us to investigate their effect on plant–microbe interactions. In addition to investigating the effects of each of these stresses singly, these changes prompt us to ask questions of increasing complexity. What happens to plant–microbe interactions in the presence of more than one environmental stress? In the natural world, plants associate with more than one microbe at a time—how does abiotic stress affect interactions within the microbial community to affect plant health? And most importantly, how can we translate this increased understanding of the interactions between plants, microbes, and the environment to the field?
