The Viruses of <i>Botrytis cinerea</i> and Beyond: Molecular Characterization of RNA Viruses and Retroplasmids.

ABSTRACT: Over the past five years, research has progressively revealed a rich diversity of RNA viruses in Botrytis cinerea. In this study, we identified nine RNA viruses from the viromes of three B. cinerea strains, including five mitoviruses, one umbra-like virus, and three partitiviruses. Among these, Sclerotinia sclerotiorum partitivirus 1 (SsPV1) was artificially introduced in a previous study. Excluding SsPV1, we cloned the other two partitiviruses and confirmed that both belong to Gammapartitivirus and contain three genomic segments, with dsRNA3 as an RNA satellite. In addition to RNA viruses, we discovered 12 retroplasmids in the three B. cinerea strains. These retroplasmids utilize the mitochondrial genetic codes and only encode a single open reading frame, which
