Comparison of CBSV- and UCBSV-derived small RNA populations recovered from infected and uninfected plants of TME 204, 60444 and NASE 3 (n = 3). The histograms represent (A) sRNA mapped to CBSV and UCBSV genomes in sense and antisense orientations, (B) Total sRNA sorted by percent nucleotide sequence lengths, (C) sRNA mapped to CBSV and UCBSV genomes, sorted by sequence lengths and orientations, and (D) unique (non-redundant) sRNA mapped to CBSV and UCBSV genomes, sorted by sequence lengths and orientations. Error bars indicate standard error of the mean (SEM).
