Figure 6. Relative abundance of TMV-Cg-derived 21-nt siRNAs with a distinct 5′-terminal nucleotide.

The TMV-Cg-derived 21-nt sense (green) and antisense (red) siRNAs recovered from infected wild type Arabidopsis (Col-0; 3 dpi) were grouped based on their 5′-terminal nucleotide identity. The relative abundance of the viral siRNAs in each group was calculated as the percentage of the total based either on small RNA reads (A) or on the number of distinct small RNA sequences (B).
