Phylogenetics, gene duplication and divergence of AnTLP genes. (a) The phylogenetic tree of AnTLP family. Different colors represented different cluster. (b) The distribution of segmental duplication genes of AnTLP on the chromosome of A. nanus. (c) Homologous gene pairs between A. nanus and V. vinifera, A. thaliana, M. truncatula, T. pratense, and L. albus, respectively, and the red lines indicate AnTLPs. (d) Evolution of TLP gene family in A. nanus and five relative species. Black numbers represent the time of species differentiation, red numbers represent the number of orthologous genes of AnTLP lost or increased during evolution, and blue numbers represent the number of orthologous genes in AnTLP genes. The gene names represented by red and blue numbers are listed in Table S2. The pictures of A. nanus, V. vinifera, A. thaliana, M. truncatula, T. pratense, and L. albus were obtained from the Plant Photo Bank of China (PPBC).
