Phylogenetic analysis of NAC proteins in safflower and Arabidopsis. The neighbor-joining (NJ) phylogenetic tree was constructed using MEGA X with 1000 bootstrap replications. The tree divided the CtNAC proteins into 17 subfamilies represented by different colored clusters within the tree. CtNACs indicates the NAC proteins from safflower. ANACs represents the NAC proteins from A. thaliana.
