Extended phylogenetic analysis of a new Israeli isolate of Brevicoryne brassicae virus (BrBV-IL) suggests taxonomic revision of the genus Iflavirus

摘要

BackgroundBrevicoryne brassicae virus (BrBV) is a positive-strand genomic RNA virus which is unassigned tentative member of the genus Iflavirus. BrBv was first identified and characterized in the late 90’s in the cabbage aphid in the United Kingdom (UK) (J Gen Virol 88:2590–2595, 2007) and was fully sequenced, using random amplification of encapsidated RNA. No other reports have been published demonstrating detection of this virus outside the UK.
