From: Large-scale analysis of the ARF and Aux/IAA gene families in 406 horticultural and other plants
The ancient evolutionary trajectory of ARF and Aux/IAA family genes in plants. a The evolutionary trajectory of ARF genes in plants. b The evolutionary trajectory of Aux/IAA genes in plants. The eight major plant lineages are represented by different colors’ solid round rectangles indicate the presence of ARF and Aux/IAA family genes in the corresponding plant lineages, and dashed rectangles suggest the absence of genes due to gene losses. Inferred ancient gene duplications are depicted as red pentacles
