Rice false smut (RFS), caused by Ustilaginoidea virens, is a significant grain disease in rice that can lead to reduced yield and quality. In order obtain spatiotemporal change information, multitemporal hyperspectral UAV data were used this study determine the sensitive wavebands for RFS identification, 665–685 705–880 nm. Then, two methods extraction of smut-infected areas, one based on spect...

Mixed infection by three dsRNA viruses, a novel betapartitivirus, a gammapartitivirus, and a novel fusarivirus, has been identified in four isolates of the obligate alkalophilic fungus Sodiomyces alkalinus. The first, Sodiomyces alkalinus partitivirus 1 (SaPV1), is placed within the genus Betapartitivirus and is related to Ustilaginoidea virens partitivirus 2. The taxonomic position of the seco...

Abstract Ustilaginoidea virens , the causal agent of rice false smut, is an economically important filamentous fungal pathogen. A high-quality reference genome U. promotes understanding molecular mechanisms underlying its virulence and pathogenicity. Here, we report first chromosome-level assembly consisting seven chromosomes ranging from 2.4 to 7.5 Mb. The has dramatic improvements over previo...
