Abundance of 21-nt siRNAs and phasing scores of antisense strand. Data of phase 11 of antisense strand siRNAs, in which total number of contiguous siRNA units was highest in J-type (see Figure 9), are shown. Cycle 1 corresponds to the phased siRNA mapped at the upstream end of contiguous units in J-type (Figure 9). For other details, see legend to Figure 10.
