A maximum-likelihood phylogenetic analysis of the NAM and CUC3 clades of the NAC family. Gene name prefixes indicate the source organisms: Ama, Antirrhinum majus; ANAC or Ath, Arabidopsis thaliana; Atr, Amborella trichopoda; Bna, Brassica napus; Bol, Brassica oleracea; Bra, Brassica rapa; Chi, Cardamine hirsuta; Ggn, Gnetum gnemon; Phy, Petunia hybrida; PNAC or Ptr, Populus trichocarpa; Psa, Pisum sativum; Rsa, Raphanus sativus; Vvi, Vitis vinifera. Full sequence accession details are given in Table S1, and the nucleotide sites used to generate the phylogeny are shown in Fig. S1. Bootstrap support values ≥50 % are indicated at corresponding nodes, while sites of regulation by miR164, and a partially conserved C-terminal protein motif of unknown function, are shown to the right of the corresponding sequences.
