Syntenic and evolutionary analysis of GmPP2Cs. A Syntenic analysis of the duplicated GmPP2Cs. GmPP2Cs from the same subfamily were linked by the same colored line. The syntenic blocks, which contained more than three GmPP2Cs, were shown by the color. B Distribution of Ks values for all duplicated genes in soybean (red line) and the duplicated GmPP2Cs (blue line). C-E Comparison of Ka (C), Ks (D) and Ka/Ks (E) distribution between the duplicated genes and duplicated GmPP2Cs in the soybean. F-H Comparison of Ka (F), Ks (G) and Ka/Ks (H) distribution of the duplicated GmPP2Cs in the different subfamilies. Asterisks represent significant differences (P < 0.05)
