*dN/dS values were shown for maize JAZ clades. dN and dS values were shown separately at lower and upper corner, respectively for between data. To be considered under purify selection, a dN/dS ratio less than 1 (dS>dN) and a p-value for the Z-test below 0.05 were required (*, P < 0.05). According to these criteria, almost all JAZ genes were determined to be under purify selection, except for JAZ group 4 which was under neutral selection. 16 ZmJAZ sequences in total were included in this analysis
