Quality characteristics of the assembled Unigenes from Chinese fir. (a) Distribution of the high-quality reads used in the assembly on the assembled Unigenes. (b) Distribution of the Illumina sequencing reads in all the assembled Unigenes. The x-axis indicates the relative position of sequencing reads in the assembled Unigenes. The orientation of Unigene is from the 5’ to 3’ end.
