Fig. 4From: Comparative analysis of transcriptomic data shows the effects of multiple evolutionary selection processes on codon usage in Marsupenaeus japonicus and Marsupenaeus pulchricaudatusCorrespondence analysis (a), correlation analysis (b) and GC content effect codon preference of M. japonicus (c) and M. pulchricaudatus (d). Different colors represent different GC contents, green represents GC% < 45%, yellow represents GC between 45and 60, and brown represents GC% > 60%Back to article page
