Phylogenetic tree of CsaGRAS genes in Cucumber, Arabidopsis and Tomato. The phylogenetic tree was constructed by the Neighbor-joining method, with 1000 bootstrap repeats. 10 classifies are represented by different colors, and the name of each subfamily is also marked in the corresponding position. The GRAS genes of the three species are represented by different colors stars: green for cucumber, yellow for Arabidopsis and red for tomato.
