Abstract

We characterised the virus-derived small interfering RNAs (vsiRNA) of bamboo mosaic virus (Ba-vsiRNAs) and its associated satellite RNA (satRNA)-derived siRNAs (satsiRNAs) in a bamboo plant (Dendrocalamus latiflorus) by deep sequencing. Ba-vsiRNAs and satsiRNAs of 21–22 nt in length, with both (+) and (-) polarity, predominated. The 5′-terminal base of Ba-vsiRNA was biased towards A, whereas a bias towards C/U was observed in sense satsiRNAs, and towards A in antisense satsiRNAs. A large set of bamboo genes were identified as potential targets of Ba-vsiRNAs and satsiRNAs, revealing RNA silencing-based virus-host interactions in plants. Moreover, we isolated and characterised new isolates of bamboo mosaic virus (BaMV; 6,350 nt) and BaMV-associated satRNA (satBaMV; 834 nt), designated BaMV-MAZSL1 and satBaMV-MAZSL1, respectively.
