Genome‐wide prediction of cloned disease resistance homologues across the Oryza genus

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract The wild relatives of rice (Oryza sativa L.) represent reservoirs of genetic diversity and potential sources of novel pest and disease resistance. The recent availability of high‐quality Oryza genome assemblies has enabled greater exploration of this diversity across the genus.

The Biological Roles of Class II Hydrophobins at the Cell Wall of Filamentous Ascomycetes

Journal of Basic Microbiology, Volume 66, Issue 10, October 2026.
ABSTRACT One of the most elusive aspects of fungal cell wall biology has been dilucidating the specific functions of most cell wall proteins. Class II hydrophobins are small amphipathic proteins produced exclusively by filamentous ascomycetes. A comparative synthesis of their biological functions across species has been lacking for this specific group ...

Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

Journal of Integrative Plant Biology, Volume 68, Issue 10, Page 3776-3789, October 2026.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.

The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

Journal of Integrative Plant Biology, Volume 68, Issue 10, Page 3830-3845, October 2026.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...

Disabling a conserved module confers broad‐spectrum resistance

Journal of Integrative Plant Biology, Volume 68, Issue 10, Page 3537-3539, October 2026.
This commentary reviews the discovery by Yuan et al. of a conserved susceptibility module where fungal Gas2 stabilizes host SnRK1β1A to suppress nuclear immunity in rice. It discusses the mechanism for broad‐spectrum resistance via genome editing and considers the essential balance between enhanced defense and associated agronomic trade‐offs.

Hot spots for diversity of Magnaporthe oryzae physiological races in irrigated rice fields in Brazil Alta diversidade de raças fisiológicas de Magnaporthe oryzae em áreas de arroz irrigado em Tocantins, Brasil

Pesquisa Agropecuária Brasileira, 2010
The objective of this work was to evaluate the Magnaporthe oryzae pathotype diversity in new commercial irrigated rice fields in the Araguaia River Valley, state of Tocantins, Brazil. The causal agent of rice blast has heavily affected rice production in

Polyphenism Through RNA Chemical Modifications

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Polyphenism, the capacity of a single genotype to produce discrete phenotypes in response to environmental cues, has long served as a model for understanding developmental plasticity. While classical studies have highlighted hormonal signalling and transcription‐factor‐driven gene regulatory networks that mediate these environmentally induced ...

Gene Flow between Divergent Cereal- and Grass-Specific Lineages of the Rice Blast Fungus Magnaporthe oryzae

mBio, 2018
Delineating species and epidemic lineages in fungal plant pathogens is critical to our understanding of disease emergence and the structure of fungal biodiversity and also informs international regulatory decisions. Pyricularia oryzae (syn.

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity

Plant, Cell &Environment, Volume 49, Issue 10, Page 7604-7618, October 2026.
ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.
