Temporal Dynamics of Viral Load and Genomic Diversity of Plantago Asiatica Mosaic Virus During Long-Term Infection in a Herbaceous Perennial.

Plant positive-strand RNA viruses exhibit high mutation rates that drive genetic diversity and adaptation to different hosts. While herbaceous perennials potentially serve as reservoirs for viral diversification through persistent infections, the mechanisms underlying this process remain largely unexplored. We investig...

Preferential Accumulation of Tomato Chlorosis Virus in Lower‐to‐Middle Leaves in Nicotiana benthamiana and Tomato Plants

Tomato chlorosis virus (ToCV), a member of the genus Crinivirus , is an emerging concern in agriculture worldwide. ToCV‐infected plants exhibit yellowing symptoms mainly in lower and middle leaves, while upper leaves remain asymptomatic. Because these symptoms resemble physiological disorders, recognition of ToCV...

Genome characterization of two novel mitoviruses and a negative-sense single-stranded RNA mycovirus from the phytopathogenic fungus Clarireedia jacksonii

Fusarium oxysporum f. sp. crypti, a novel forma specialis causing Fusarium wilt of mitsuba, Cryptotaenia japonica.

Findings suggest that the host-pathogenic F. oxysporum isolates derived from mitsuba represent a forma specialis distinct from f.
