Figure 4From: Comparative analysis among the small RNA populations of source, sink and conductive tissues in two different plant-virus pathosystems Size distribution of MNSV and PNRSV derived sRNAs (from 16 to 35Â nt) in the eight infected samples. (A) Size distribution of MNSV derived sRNAs and (B) size distribution of PNRSV derived sRNAs. Normalized values for the different tissues are represented in colors: cotyledon (blue), leaf (red), root (green) and phloem (violet).Back to article page
