1 AtSPO11-1–Dependent sRNAs Show Enrichment at Meiotic CO-Associated DNA Motifs.
AtSPO11-1–Dependent sRNAs Show Enrichment at Meiotic CO-Associated DNA Motifs. (A) Density plot of AtSPO11-1–dependent sRNAs and AtSPO11-1 oligos (Choi et al., 2018) on the five Arabidopsis chromosomes (black bars with circles marking centromeres). sRNA density on the sense strand shows a positive value (plotted in black), while sRNA density on the antisense strand shows a negative value (plotted in gray) per 10 kb. Chromosomes are portioned into arm regions and centromeric regions (green dashed lines). The sRNA density is compared to the density of AtSPO11-1 oligos per 10 kb (red curve). (B) Meiotic recombination-associated CTT repeat motif is enriched with meiocyte-specific and AtSPO11-1–dependent sRNAs from gene body regions. (C) Meiotic recombination-associated A-rich motif is enriched with meiocyte/leaf-shared and AtSPO11-1–dependent sRNAs from promoter regions. Jiyue Huang et al.
