Virus-derived small interfering RNAs (vsiRNAs) of cucumber green mottle mosaic virus (CGMMV), a member of the genus Tobamovirus, were characterised in cucumber plants by deep sequencing. CGMMV vsiRNAs of 21-22 nt in length predominated, suggesting that there might be a conserved mechanism of DCL2 and DCL4 involvement in the biogenesis of vsiRNAs, as well as a common RNA silencing pathway in CGMMV-infected cucumber plants. The 5'-terminal base of vsiRNAs was biased towards C/A/U, suggesting that CGMMV vsiRNAs might be loaded into diverse AGO-containing RISCs to disturb the gene expression of host plants. Possible targets for some of the vsiRNAs were also predicted.

D034741 RNA, Small Interfering Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
