  1. Clusters A, B, C, D, and E refer to ZTL in dicots cluster, LKP2 in dicots cluster, ZTL in monocots cluster, FKF1 in monocots cluster, and FKF1 in dicots, respectively. Type-I functional divergence estimate (θI ± standard error; upper right diagonal of Type-I matrix), and LRT values for significance (lower left diagonal of Type-I matrix) were estimated using DIVERGE 3.0. Type-II functional divergence estimate (θII ± standard error) is shown in the upper right diagonal of Type-II matrix. The fold score (lower left diagonal of Type-II matrix) for functional divergence estimate was obtained as θII/θSE by using the Z-score test (normal distribution test). Numbers in the parentheses are amino acid sites with a posterior probability of > 0.90
