Small RNAs originating from specific CRP coding regions. Individual abundances for small RNA signatures between 21–24 nt in length are displayed in different colors (24-mers are orange). A unique small RNA signature is displayed as a filled diamond and a duplicated small RNA signature is displayed as a hollow diamond. The exons of CRP4, CRP5a and CRP5b genes are annotated as blue or red boxes. Purple lines indicate a k-mer frequency for repeats; yellow shading indicates DNA transposon-like sequences found by RepeatMasker. Note that the majority of small RNAs originate within the CRP coding regions and not in the adjacent transposon-like sequences. The small RNA abundances were normalized to 5 transcripts per million (TPM). The sum of hits-normalized-abundance (HNA) for all small RNAs mapping to the entire gene is displayed below each gene image with the total abundance of 24 nt siRNAs in parentheses in black, followed by the count of unique 24 nt siRNAs in red text.
