Abstract Rice false smut, caused by Ustilaginoidea virens , is one of the most destructive diseases in major world rice-producing regions. Basic leucine zipper (bZIP) proteins, which belong to an evolutionarily conserved transcription factor family and play critical roles various biological processes eukaryotes, have been previously identified U. ; however, their functions still need be further...

Abstract Rice false smut caused by Ustilaginoidea virens is one of the widespread rice diseases across globe in recent years, however, we know little about its molecular mechanism infection. The cAMP signaling pathway functions directly development and formation infectious structures to regulate infection process many pathogenic fungi. In order investigate role U. , UvCap1, a cyclase-associated...

Ustiloxins were cyclopeptide mycotoxins from rice false smut balls (FSBs) that formed in rice spikelets infected by the fungal pathogen Ustilaginoidea virens. To investigate the chemical diversity of these metabolites and their bioactivities, one new cyclopeptide, ustiloxin G (1), together with four known congeners-ustiloxins A (2), B (3), D (4), and F (5)-were isolated from water extract of ri...

False smut disease (FSD) of rice incited by Ustilaginoidea virens is an emerging threat to paddy cultivation worldwide. We investigated the spatial distribution FSD in different ecosystems South Indian states, viz., Andhra Pradesh, Karnataka, Tamil Nadu, and Telangana, considering exploratory data from 111 sampling sites. Point pattern surface interpolation analyses were carried out identify pa...
