Determination of the absolute configurations of the stereogenic centers of ustilaginoidins by studying the biosynthetic monomers from a gene knockout mutant of Villosiclava virens. [PDF]
Sci Rep, 2019 AbstractUstilaginoidins are a kind of mycotoxins with 9,9′-linked bis-naphtho-γ-pyrones structures produced by the rice false smut pathogen Villosiclava virens. These metabolites displayed a wide range of bioactivities, such as teratogenic, cytotoxic, phytotoxic, and antibacterial activities. So far 26 ustilaginoidins have been isolated from V. virens,

Ustilaginoidin M1, a new bis-naphtho-γ-pyrone from the fungus Villosiclava virens [PDF]
Natural Product Research, 2019 Ustilaginoidin M1 (1), a novel bis-naphtho-γ-pyrone, was isolated from the cultures of the fungus Villosiclava virens which was the pathogen of rice false smut disease. Its structure was elucidated by spectroscopic analysis and by comparison of its physical and spectroscopic data with the literature.

Genetic diversity analysis reveals that geographical environment plays a more important role than rice cultivar in Villosiclava virens population selection. [PDF]
Appl Environ Microbiol, 2014 ABSTRACT Rice false smut caused by Villosiclava virens is an economically important disease of grains worldwide. The genetic diversity of 153 isolates from six fields located in Wuhan (WH), Yichang Wangjia (YCW), Yichang Yaohe (YCY), Huanggang (HG), Yangxin (YX), and Jingzhou (JZ) in Hubei province of ...

Simple transformation of the rice false smut fungus Villosiclava virens by electroporation of intact conidia [PDF]
Mycoscience, 2011 A simple procedure is reported for transformation of the rice false smut fungus Villosiclava virens (anamorph: Ustilaginoidea virens) using electroporation of intact conidial cells. The transformation vector pCB1004eGFP was constructed with a green fluorescent protein (eGFP) gene under a constitutive promoter of the glyceraldehyde-3-phosphate ...
