Rice False Smut Fungus, Ustilaginoidea virens, Inhibits Pollen Germination and Degrades the Integuments of Rice Ovule
Ustilaginoidea virens is a flower-infecting fungus that forms false smut balls in rice panicle. Rice false smut has long been considered a minor disease, but recently it occurred frequently and emerged as a major disease in rice production. In vitro co-cultivation of U. virens strain with young rice panicles showed that U. virens enters inside of spikelets from the apex and then grows downward ...
متن کاملGenome Sequence of Ustilaginoidea virens IPU010, a Rice Pathogenic Fungus Causing False Smut
Ustilaginoidea virens is a rice pathogenic fungus that causes false smut disease, a disease that seriously damages the yield and quality of the grain. Analysis of the U. virens IPU010 33.6-Mb genome sequence will aid in the understanding of the pathogenicity of the strain, particularly in regard to effector proteins and secondary metabolic genes.
متن کاملUvHOG1 is important for hyphal growth and stress responses in the rice false smut fungus Ustilaginoidea virens
Rice false smut caused by Ustilaginoidea virens is one of the most important diseases of rice worldwide. Although its genome has been sequenced, to date there is no report on targeted gene deletion in U. virens and no molecular studies on genetic mechanisms regulating the infection processes of this destructive pathogen. In this study, we attempted to generate knockout mutants of the ortholog o...
متن کاملPEST MANAGEMENT: DISEASES Infection of Plants of Selected Rice Cultivars by the False Smut Fungus, Ustilaginoidea virens, in Arkansas
False smut, caused by Ustilaginoidea virens, has recently been found in Arkansas. Plants infected by the fungus remain symptom-free until heading and it is difficult to see spores on contaminated seeds. Field tests were conducted in 2006 to determine the effect of false-smut inoculation of rice seeds on the yields of selected rice cultivars. Seeds were inoculated by vacuum infiltration in suspe...
متن کاملDetermination and Analysis of Ustiloxins A and B by LC-ESI-MS and HPLC in False Smut Balls of Rice
Ustiloxins are cyclopeptide mycotoxins produced by the pathogenic fungus Villosiclava virens of rice false smut. Ustiloxins A and B as two main mycotoxins were determined conveniently by LC-ESI-MS in the water extract from rice false smut balls which were mostly composed of the chlamydospores and mycelia of the pathogen. Both ustiloxins A and B in the water extract were also quantitatively anal...
