Figure 2From: Genome-wide analysis of Aux/IAA and ARF gene families in Populus trichocarpaPhylogenetic analysis of predicted full-length Aux/IAA protein sequences using Neighbor-Joining method. Amino acid sequences of full-length predicted proteins were aligned using MUSCLE program. Tree was produced as described in methods. Bootstrap support is indicated at each node. Green boxes represent sustained expansion of subgroups in Populus.Back to article page
