Fig. 2

Abundance and distribution of mapped reads along gene structure. a the mapped reads are calculated to RPKM to reveal gene abundance, and the accumulative expression of gene levels in each sample is plotted. b the distribution of mapped reads 1 kb up and downstream of stop codon is plotted. C. the distribution of mapped reads 1 kb up and downstream of transcription terminal site is plotted. The arrows indicate the peaks of reads accumulation, and the associated numbers indicate the location according to the stop codon (b) and transcription terminal site (c). The vertical lines indicate the location of stop codon (b) and transcription terminal site (c)
