TE-derived 21-nt and 24-nt sRNAs correlate, a–b Correlation between 21-nt and 24-nt sRNA mapped to each TE subfamily in pollen (a) and in somatic embryonic callus at 22 °C (b). TE families that had a limited number of sRNAs were omitted. c sRNA colored by size at sRNA clustered regions in pollen. d Read density of 21-nt and 24-nt sRNA are shown as histograms at representative loci
