Fig. 4From: Identification and characterization of a maize-associated mastrevirus in China by deep sequencing small RNA populationsCharacterization of MSRV-YN derived siRNAs. a Size distribution of total vsiRNAs for MSRV-YN. b Relative frequency of the four different 5’-terminal nucleotides in 20–25-nt vsiRNAs and total vsiRNAs. c Polarity distribution of the 20–25-nt vsiRNAs and total vsiRNAs that perfectly matched the virion sense strand (+) and complementary sense strand (−) genomic sequence. Histograms represent the ratios of total vsiRNAs within each categoryBack to article page
