Figure 3. Phylogenetic relationships of SOG-like proteins. The phylogenetic tree was constructed by the neighbor-joining method in MEGA5.2.2 based on the cDNA sequence of NAC domains. The NAC proteins in A. thaliana are labeled “ANAC.” The bracketed names are AGI_codes from TAIR (http://www.arabidopsis.org). ANAC005 and ANAC006 were used as outgroups. Bootstrap probabilities are given at each branching point. Values < 50 are not significant. The parenthetical numbers are DDBJ, NCBI, GenBank accession numbers (http://www.ddbj.nig.ac.jp, https://www.ncbi.nlm.nih.gov). The amino acid sequence of the starred (*) genes were used for alignment analysis in Figure 4.
