Comparative genomic analysis of the PP2C members in soybean and grape. A Microcollinearity patterns between the genomic regions from soybean (top) and grape (down). Gray lines connected orthologous gene pairs, and orthologous PP2Cs were marked with red lines. B Comparison of different orthologous gene types in the PP2C subfamily. Yellow: one VvPP2C had one orthologous GmPP2C. Red: one VvPP2C had two orthologous GmPP2Cs. Blue: one VvPP2C had three orthologous GmPP2Cs. Pink: one VvPP2C had four orthologous GmPP2Cs. C Distribution of Ks values for all orthologous gene pairs (red line) and PP2Cs (blue line) in soybean and grape. D-F Comparison of Ks (D), Ka (E) and Ka/Ks (F) distribution between all of the orthologous gene pairs and PP2Cs in soybean and grape. G-I Comparison of Ks (G), Ka (H) and Ka/Ks (I) distribution of the orthologous GmPP2Cs and VvPP2Cs in the different subfamilies. Asterisks represent significant differences (P < 0.05)
