Heat map and PCA analysis of RSCU of synonymous codons from Chinese bayberry and 26 other plants. The magenta, reddish-brown, purple, orange and cyan spots represent the Chlorophytes, Bryophytes, Pteridophytes, Monocotyledons and Eudicotyledons, respectively. A) Heat map of RSCU of 59 codons from 27 species using Euclidean distance and complete linkage clustering module. B) The PCA analysis of RSCU of 59 codons from 27 species on the primary and secondary axes (accounting for 84.38% and 7.38% of the total variation, respectively). C) Variance contribution ratio and accumulated variance contribution ratio of the first ten principal components of Part B. D) Quality of representation of the first two principal components of Part B, the red and green spots represent the quality of representation of PC1 and PC2, respectively.
