Size distribution of sequenced siRNAs obtained from the VARX plant.

<p>The histograms represent the numbers of siRNA reads in each size class. (A) The size distributions of total reads, (B) The size distributions of reads mapping to the <i>rep</i> gene C-sense intronic region of SWSV, (C) The size distributions of reads mapping to the V1–V2 ORFs region of SWSV and (D) The size distributions of reads mapping to the C1 ORF region of SWSV.</p

Maximum-likelihood phylogenetic tree of 63 virus isolates representing each known mastrevirus species (including major strains) and the 6 SWSV isolates determined in this study.

<p>Tree branches are coloured according to the geographical origins of the viruses. Branches marked with filled and open circles respectively have >95% and 80–94% approximate likelihood ratio test support; branches having <80% support were collapsed. The phylogenetic tree is rooted using the full genome sequence of Dicot-infecting mastreviruses.</p
