Cultural, Molecular and Genetic Variability of Ustilaginoidea virens Causing Rice False Smut Disease
Rice false smut disease is caused by Ustilaginoidea virens, an ascomycetous fungi. Thirty isolates of U. virens showed well defined colonies on potato sucrose medium (PSA). The maximum colony diameter was found to be 85.68 mm with a growth rate 2.85 in the UV23 isolate and minimum 10.14 0.33 mm, which observed UV15 isolate. However, thirty exhibit various cultural morphological characteristics ...
brassica napus is an important oilseed crop and the yield loss due to fungal disease stem rot caused by sclerotinia sclerotiorum is a serious problem in cultivation of this crop. the pathogenesis-related (pr) protein, glucanase, hydrolyzes a major cell wall component, glucan, of the pathogenic fungi and acts as a plant defense barrier. in this study, a β-1,3-glucanase (bgn13.1) gene was isolate...
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...
