Deep sequencing of mycovirus-derived small RNAs from Botrytis species.

ABSTRACT: RNA silencing is an ancient regulatory mechanism operating in all eukaryotic cells. In fungi, it was first discovered in Neurospora crassa, although its potential as a defence mechanism against mycoviruses was first reported in Cryphonectria parasitica and, later, in several fungal species. There is little evidence of the antiviral potential of RNA silencing in the phytopathogenic species of the fungal genus Botrytis. Moreover, little is known about the RNA silencing components in these fungi, although the analysis of public genome databases identified two Dicer-like genes in B. cinerea, as in most of the ascomycetes sequenced to date. In this work, we used deep sequencing to study the virus-derived small RNA (vsiRNA) populations from different mycoviruses infecting field isolates of Botry
