Fig. 4From: Amazing symmetrical clustering in chloroplast genomesThe distribution of 11 118 fragments of moss Physcomitrella patens chloroplast genome (AC AP005672). (a) and (c) are (PC1,PC2) view, (b) and (d) are (PC2,PC3) view; (a) and (b) shows the distribution of all fragments, (c) and (d) show the distribution with coding fragments erased. Coloring and placing is the same as in Fig. 1Back to article page
