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...

Sugarcane smut is a fungal disease caused by Sporisorium scitamineum, which can cause severe economic losses in sugarcane industry. The infection depends on the mating of bipolar sporida to form a dikaryon and develops into hyphae to penetrate the meristematic tissue of sugarcane. In this study, we set to isolate bacterial strains capable of blocking the fungal mating and evaluate their potenti...

Extracellular vesicles (EVs) can transfer diverse RNA cargo for intercellular communication. EV-associated RNAs have been found in fungi and were proposed to be relevant pathogenesis animal hosts. In plant-pathogen interactions, small are exchanged a cross-kingdom RNAi warfare EVs considered delivery mechanism. To extend the search molecules involved communication, we characterised repertoire o...

In the phytopathogenic fungus Ustilago hordei, one locus with two alternate alleles, MAT-1 and MAT-2, controls mating and the establishment of the infectious dikaryon (bipolar mating). In contrast, for U. maydis, these functions are associated with two different gene complexes, called a and b (tetrapolar mating); the a complex has two alternate specificities, and the b gene complex is multialle...

The isolation from bud scales and partial characterisation of highly active, low molecular weight, germination inhibitors, in concentrations correlated quantitively with resistance of N52/219, N11, NCo376, and NCo293, holds promise for the development of a rapid, quantitative, chemical assay for evaluating sugarcane for pre-infectional resistance to smut. Histopathological studies on stalk and ...

A case of hypersensitivity pneumonitis caused by a smut fungus Ustilago esculenta is presented.

Variation in the currently recognized species, Barbatula nuda (Bleeker 1865), from North China was studied, and three distinct species are identified: B. nuda, B. toni, and B. gibba sp. nov.. The name B. nuda is presently misapplied; this species is distinct from B. toni, a species widely distributed in Northeast China, and occurs only in the Liao-He basin of Liaoning Province and the Tumen-Jia...

The constitution and regulation of effector repertoires shape host–microbe interactions. Ustilago maydis Sporisorium reilianum are two closely related smut fungi, which both infect maize but cause distinct disease symptoms. Understanding how orthologs regulated in these pathogens can therefore provide insights into the evolution different infection strategies. We tracked progress U. S. leaves u...

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...
