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

Biosynthesis, chemical structure, and structure-activity relationship of orfamide lipopeptides produced by Pseudomonas protegens and related species [PDF]

, 2016
Orfamide type cyclic lipopeptides (CLPs) are biosurfactants produced by Pseudomonas and involved in lysis of oomycete zoospores, biocontrol of Rhizoctonia and insecticidal activity against aphids.

A Non‐Host Pathogen Elicitor Induces Blast Resistance Mediated by OsNAC78‐Pir7b Module in Rice

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants exhibit broad‐spectrum and persistent resistance induced by non‐host pathogens. Previous studies have found that syringolin A secreted by Pseudomonas syringae pv. syringae can activate the expression of defense‐related gene Pir7b in non‐host rice, but the underlying mechanism remains ambiguous.

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.

CRISPR-Cas9 ribonucleoprotein-mediated co-editing and counterselection in the rice blast fungus [PDF]

, 2001
The rice blast fungus Magnaporthe oryzae is the most serious pathogen of cultivated rice and a significant threat to global food security. To accelerate targeted mutation and specific genome editing in this species, we have developed a rapid plasmid-free

A Meta‐Analysis Reveals That the Protective Role of Silicon in Grasses Against Fungal Pathogens Depends on Infection Mechanism

Plant, Cell &Environment, EarlyView.
ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

In silico reversal of repeat-induced point mutation (RIP) identifies the origins of repeat families and uncovers obscured duplicated genes [PDF]

, 2010
Background: Repeat-induced point mutation (RIP) is a fungal genome defence mechanism guarding against transposon invasion. RIP mutates the sequence of repeated DNA and over time renders the affected regions unrecognisable by similarity search tools such ...

Effects of applying Trichoderma asperellum to rice (Oryza sativa) on phytobiome and plant responses

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
We investigated the effect of dipping at transplanting or post‐transplanting spray application on the root‐associated microbiome or leaf epiphytes via amplicon sequencing, and on plant responses via RNA‐seq. Both root dipping and foliar application with Trichoderma asperellum spore suspension only had a limited impact on the leaf epiphytes and root ...

Integrated Single‐Cell and Spatial Transcriptomics Reveal Cell‐Type‐Specific Immune Regulatory Networks in Maize Responding to Southern Corn Rust

Advanced Science, Volume 13, Issue 27, 13 May 2026.
By integrating single‐nuclei and spatial transcriptomics, this study presents a stereoscopic landscape of maize leaf to Puccinia polysora infection. Epidermal and mesophyll cells initiate primary defenses via RLPs/RLKs and jasmonic acid signaling. Cell‐cell communication analyses further reveal the underlying the dynamics of the underlying immune ...
