From: Characterization of the chloroplast genome of Gleditsia species and comparative analysis
Codon bias analysis and selective pressures in the evolution. (a): Codon content of 20 amino acids and stop codons in all protein-coding genes of Gleditsia chloroplast genome; (b): Distribution of codon preference in Gleditsia; (c): Ka/Ks values of protein-coding genes of the seven comparative combinations. Note In the a, the top panel shows the RSCU for the corresponding amino acids, the colored block which are shown in the below represent different codons; In (c), Ka: nonsynonymous; Ks: synonymous.
