Examples of loci generating phased 21-nt small RNAs (FH494072 and FH698163) and phased 24-nt small RNAs (ET713388, ET712651 and ET977252). The middle and the top graph in each locus represent the distribution of small RNA reads across the whole locus and the phase signals generated from the small RNA reads, respectively. Each arrow underneath the plot graph represents a 21-nt or 24-nt phase with the arrow direction indicating the forward or the reverse strand. The red arrows represent the phase with the highest number of small RNA reads. Target(s) of the phased small RNA corresponding to the red arrow, identified by degradome sequencing, are shown at the bottom of each graph.
