Figure 6. Distribution of plastid small RNAs in the Deschampsia antarctica chloroplast genome.

Figure 6

The reads from small RNA-seq were divided into two groups according to the length (20–24 nt and >30 nt) and aligned to the D. antarctica chloroplast genome with 100% identity. The distributions of reads were compared between the two groups. In total, 12,753,636 reads were distributed unevenly in the chloroplast genome with high density in the coding regions of psbA and rbcL, intergenic regions, and inverted repeat regions in which most of the rRNA genes exist. The 27 loci enriched with 20–24 nt RNAs are indicated in red, along with the number of reads. The y-axis shows the number of reads (from 0 to 1000).
