Fig. 2From: Over-expression of poplar NAC15 gene enhances wood formation in transgenic tobaccoConserved domain alignment and phylogenetic analysis of NACs from 12 different plant species. The conserved NAC domain can be divided to 5 sub-domains (A-E). The colorful horizontal bars represent the start and end positions of each sub-domain. a Domain alignment of NACs by Clustal W; b Phylogenetic tree of NACs constructed by Neighbor-Joining method with MEGA 6 programBack to article page
