Coexistence of Multiple Endemic and Pandemic Lineages of the Rice Blast Pathogen

mBio, 2018
The rice blast fungus Magnaporthe oryzae (syn., Pyricularia oryzae) is both a threat to global food security and a model for plant pathology. Molecular pathologists need an accurate understanding of the origins and line of descent of M.

Exploring fungal endophytes as biocontrol agents against rice blast disease

Acta Agrobotanica
The rice blast disease caused by Pyricularia oryzae Cavara is among the most severe plant diseases in the world. The utilization of natural antagonists, such as fungal endophytes, can be a good method to control the spread of this disease.

Green synthesis of silver nanoparticles using fermentation extracts from a mangrove soil bacterium: morphological characterization, and antifungal activities against rice blast fungus

Pest Management Science, Volume 82, Issue 2, Page 2035-2047, February 2026.
This study synthesized silver nanoparticles (RFE‐AgNPs) with multifaceted inhibitory effects on Pyricularia oryzae using mangrove soil bacterial natural products and evaluated their toxicity effects on Artemia salina. Abstract BACKGROUND Rice blast, caused by Pyricularia oryzae, poses a formidable threat to global rice production.

Evaluation of chitinase production ability to antagonize Pyricularia Oryzae of bacteria and actinomycete strains isolated from rice root soil in Kien Giang Province

Tạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Kỹ thuật và Công nghệ
The fungus Pyricularia oryzae is one of the agents causing rice blast disease. The mechanism of the infection is directing penetration through the plasma membrane, secreting cytotoxins, and forming infectious cells specialized for causing disease in rice

Cross‐Species Transfer of the Maize NAM‐ATAF1/2‐CUC2 Transcription Factor ZmNAC2 Confers Disease Resistance in Transgenic Rice Without a Yield Penalty

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The maize ZmNAC2 gene, which encodes an NAM‐ATAF1/2‐CUC2 (NAC2) transcription factor, confers broad‐spectrum disease resistance (BSR) when introduced into rice without compromising yield. BSS, broad‐spectrum susceptibility. ABSTRACT Rice is a staple crop feeding over half of the global population, yet it faces severe yield losses due to devastating ...

A Core Effector MoPce1 Is Required for the Pathogenicity of Magnaporthe oryzae by Modulating Catalase‐Mediated H2O2 Homeostasis in Rice

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
MoPce1, an atypical CAP/PR‐1 family effector, is essential for Magnaporthe oryzae virulence. MoPce1 functions by interacting with the rice catalase OsCATC to disrupt ROS homeostasis, thereby promoting host susceptibility. ABSTRACT Plant pathogens employ a diverse array of effectors to facilitate host colonisation, including evolutionarily conserved ...

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.
