A Novel Effector Gene SCRE2 Contributes to Full Virulence of Ustilaginoidea virens to Rice

Frontiers in Microbiology, 2019
Ustilaginoidea virens, the causal agent of rice false smut (RFS), has become one of the most devastating rice pathogens worldwide. As a group of essential virulence factors, the effectors in the filamentous fungus might play central roles in the ...

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.

Multi‐Decadal Analysis on the Impact of Climate Change, Genetic Gain, Cultivar Type, and Harvest Timing on Main and Ratoon Rice Yield and Quality

Global Change Biology, Volume 32, Issue 1, January 2026.
An analysis of 33 years of data estimated the impact of climate change, genetic gain, cultivar type, and harvest timing on rice yield and quality. Degree‐days (˚D) and atmospheric [CO2] have increased 11.6% and 18.4%, respectively. Several climatic variables have impacted grain yield, some positively and some negatively, and many have reduced grain ...

Secreted Glycoside Hydrolase BcGH61 From Botrytis cinerea Induces Cell Death by the Apoplastic Location and Triggers Intracellular Immune Perception

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
We present a dual‐action virulence paradigm for BcGH61: Extracellularly, BcGH61 glycoside hydrolase degrades cell walls, releasing DAMPs that activate PRR‐mediated cell death. Intracellularly, it targets chloroplasts via NbHrBP1 interaction at plastoglobule‐thylakoid interfaces, paradoxically activating defence signalling while priming immunity‐related

Rapid detection of the rice false smut fungus Ustilaginoidea virens by lateral flow strip-based recombinase polymerase amplification assay

Journal of Integrative Agriculture
Rice false smut, caused by Ustilaginoidea virens, is a devastating disease that greatly reduces rice yield and quality. However, controlling rice false smut disease is challenging due to the unique infection mode of U. virens.

Calcineurin-dependent transcription factor CRZ1, an important pathogenicity factor in Ustilaginoidea virens, directly regulates ustilaginoidin biosynthesis

Phytopathology Research
Ustilaginoidea virens, the causal agent of rice false smut, produces a variety of mycotoxins, including ustilaginoidins, which are highly toxic and harmful to humans and animals.

Uvpks1, Involved in Ustilaginoidin Biosynthesis, Contributes to the Metabolic Profile, Development, Stress Responses, and Pathogenicity in Villosiclava virens

Journal of Fungi
Villosiclava virens (anamorph: Ustilaginoidea virens) is a fungal pathogen that causes rice false smut, one of the most devastating diseases of rice. The Uvpks1 gene encoding polyketide synthase is responsible for the biosynthesis of ustilaginoidins, a ...

S-palmitoylation of MAP kinase is essential for fungal virulence

mBio
S-palmitoylation is an important reversible protein post-translational modification in organisms. However, its role in fungi is uncertain. Here, we found the treatment of the rice false fungus Ustilaginoidea virens with S-palmitoylation inhibitor 2 BP ...
