Main Ustilaginoidins and Their Distribution in Rice False Smut Balls [PDF]

Toxins, 2015
Rice false smut has become an increasingly serious fungal disease in rice (Oryza sativa L.) production worldwide. Ustilaginoidins are bis-naphtho-γ-pyrone mycotoxins previously isolated from the rice false smut balls (FSBs) infected by the pathogen ...

Development of a Monoclonal Antibody-Based icELISA for the Detection of Ustiloxin B in Rice False Smut Balls and Rice Grains [PDF]

Toxins, 2015
Rice false smut is an emerging and economically-important rice disease caused by infection by the fungal pathogen Villosiclava virens. Ustiloxin B is an antimitotic cyclopeptide mycotoxin isolated from the rice false smut balls that formed in the ...

An Ustilaginoidea virens Nuclear Effector SCRE7 Inhibits Rice Immunity via Suppressing OsLBD11/12-Promoted Transcription of OsCPS2. [PDF]

Plant Biotechnol J
ABSTRACT Phytopathogenic fungi secrete a great number of effector proteins into various organelles of host plants and suppress plant immunity through different mechanisms. In this study, we identify SCRE7 as a unique nuclear effector that is essential for U. virens infection.

Characterization of mating-type loci in rice false smut fungus Villosiclava virens [PDF]

FEMS Microbiology Letters, 2015
Ascospores of Villosiclava virens are a primary infection source of rice false smut. This phytopathogenic fungus exists in heterothallic form, and mating compatibility is regulated by mating-type locus 1 (MAT1). However, the MAT1 locus structure remains unknown. The MAT1-1 and MAT1-2 idiomorphs of V. virens were characterized and annotated on the basis

An Ustilaginoidea virens glycoside hydrolase 42 protein is an essential virulence factor and elicits plant immunity as a PAMP

Molecular Plant Pathology, Volume 24, Issue 11, Page 1414-1429, November 2023., 2023
UvGHF1, as a GH42‐type glycosyl hydrolase secreted by Ustilaginoidea virens, contributes to U. virens virulence, whereas it is recognized by the rice surveillance system to trigger plant immunity. Abstract Rice false smut, caused by the ascomycete fungus Ustilaginoidea virens, which infects rice florets before heading, severely threatens rice grain ...

Higher relative humidity and more moderate temperatures increase the severity of rice false smut disease in the rice–crayfish coculture system

Food and Energy Security, Volume 11, Issue 1, February 2022., 2022
Rice false smut in rice–crayfish coculture (RC) was much more serious than the disease in rice monoculture (RM) among most rice varieties. Some varieties displayed resistance to rice false smut in RM, but were susceptible in RC, suggesting that the RC system is a better model than RM for evaluation of the resistance of rice varieties to false smut.
