Phylogenetic relationships of AUX/IAA genes in Arabidopsis thaliana, Brassica rapa ssp. pekinensis, and B. rapa ssp. rapa. The neighbor-joining phylogenetic tree was generated using MEGA 7.0 based on the alignment of full-length amino acid sequences of 29 (A) thaliana, 55 (B) rapa ssp. pekinensis, and 89 B. rapa ssp. rapa AUX/IAA proteins. Seven subgroups were displayed by colored arcs. Subgroups A1, A2, A3, A4, B1, B2, and B6 were indicted by light green, blue, purple, green, brown, red, and rose red, respectively. The 29 orthologous sets and two Brassica specific sets are indicated by colored signs. AUX/IAA genes from (A) thaliana, (B) rapa ssp. pekinensis, and B. rapa ssp. rapa were indicated by red circles, blue squares, and green stars, respectively
