Ustiloxins, antimitotic cyclic peptides from false smut balls on rice panicles caused by Ustilaginoidea virens.
Ustiloxins A (1a), B (1b), C (1c), D (1d) and E (1e), antimitotic peptides, have been isolated from the water extract of false smut balls caused on the panicles of rice plant by a fungus Ustilaginoidea virens. The structure of 1b was assigned from its spectral property and its amino acid analysis in relation to 1a whose structure was determined previously by a combination of X-ray crystallograp...
متن کاملRice 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 کاملQuantitative detection of the rice false smut pathogen Ustilaginoidea virens by real-time PCR.
Rice false smut (RFS) is an important rice disease that is caused by the pathogen Ustilaginoidea virens. In this study, we developed a real-time polymerase chain reaction (PCR) assay to detect U. virens and to estimate the level of disease. The genomic DNAs of U. virens and rice were extracted together from the rice samples. Real-time PCR assays were performed and compared to conventional neste...
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 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...
