Profile of vsiRNAs and contigs derived from library of PalMV-infected leaves. a Histogram representation of size distribution of total sRNAs in the library. b Histogram representation of total vsiRNA reads in each size class from genome and anti-genome. c Map of vsiRNAs reads at each nucleotide position of the PalMV genome. Bars above the axis represent sense reads starting at each respective position, and those below represent antisense reads ending at the respective position. d Map of continuous contigs covering most of the virus genomic sequence, except for a few gaps
