Tomato plants were infected by either agroinoculation (Agrob-TYLCV) or by B. tabaci (Bemisia-TYLCV) and data from different time points during the systemic infection are shown (7, 14 and 21 dpi). The values represent the number of vsRNA (20–25 nt) per nucleotide at distinct genomic regions according to the position of the viral 5′nucleotide. The regions are identified by the viral genes they encompass, their size (nt) and their coordinates according to the TYLCV genome map are indicated at the top. The three genomic regions that showed the maximum number of vsRNA per nucleotide (OL1, OL2 and OL3) are marked in bold. Data comes from the same biological replicates showed in Fig. 4A,B.
