AI Article Synopsis
Article Abstract
In this study, we identified a novel mycovirus, Fusarium graminearum ormycovirus 1 (FgOV1), from the pathogenic fungus Fusarium graminearum. The virus has two RNA segments, RNA1 and RNA2, with lengths of 2,591 and 1,801 nucleotides, respectively, excluding the polyA tail. Each segment contains a single open reading frame (ORF). The ORF in RNA1 encodes an RNA-dependent RNA polymerase, while the ORF in RNA2 encodes a hypothetical protein. Phylogenetic analysis showed that FgOV1 belongs to the gammaormycovirus clade, whose members are related to betaormycoviruses. To our knowledge, this is the first report of an ormycovirus in Fusarium graminearum.

Most plant pathogens secrete effector proteins to circumvent host immune responses, thereby promoting pathogen virulence. One such pathogen is the fungus , which causes Fusarium Head Blight (FHB) disease on wheat and barley. Transcriptomic analyses revealed that expresses many candidate effector proteins during early phases of the infection process, some of which are annotated as proteases.

Fusarium head blight, caused by , continues to be one of the most important and devastating fungal diseases on cereal grains including wheat, barley, and oat crops. produces toxic secondary metabolites that include trichothecene type A and type B mycotoxins. There are many variants of these toxins that are produced, and in the early 2010s, a novel type A trichothecene mycotoxin known as 3ANX (7-α hydroxy,15-deacetylcalonectrin) and its deacetylated product NX (7-α hydroxy, 3,15-dideacetylcalonectrin) were identified in Minnesota, USA.

fungi are widespread pathogens of food crops, primarily associated with the formation of mycotoxins. Therefore, effective mitigation strategies for these toxicogenic microorganisms are required. In this study, the potential of pulsed electric field (PEF) as an advanced technology of increasing use in the food processing industry was investigated to minimize the viability of pathogens and to characterize the PEF-induced changes at the metabolomic level.
