Neighbour-joining tree of subgroup III-1, 2 and 3 NAC family transcription factors in Norway spruce and Arabidopsis. Neighbour-joining tree based on the predicted amino acid sequence of the identified clade III-1, 2 and 3 NAC family transcription factors in Norway spruce gene models in P.abies 1.0 and the III-1, 2 and 3 NAC family transcription factors reported by Jensen and co-workers [1] namely AT1G77450.1 (ANAC032), AT1G01720.1 (ATAF1), AT5G63790 (ANAC102), AT5G08790 (ATAF2), AT4G27410.2 (RD26), AT1G52890 (ANAC019), AT3G15500 (ANAC055), AT1G61110 (ANAC025), AT3G15510 (ANAC056), AT1G52880 (ANAC018), AT2G33480 (ANAC041) and AT5G13180 (ANAC083). Poplar and rice sequences producing significant hits to Norway spruce clade III-3 NAC proteins: XP_002306280.1 (PNAC005), XP_002309945.1 (PNAC007), XP_002307447.1 (PNAC004), XP_002300972.1 (PaNAC006), XP_002305109.1 (PNAC043), XP_002305677.1 (PNAC048), XP_002316635.1 (PNAC047), XP_002319143.2 (PNAC090), XP_002325400.1 (PNAC091), XP_006387160.1 (PNAC120), XP_002316917.1 (PNAC118), XP_015645677.1 (ONAC010), XP_015630558.1 (OsNAC19/SNAC1), XP_015615093.1 (OsNAC29), XP_015620920.1 (OsNAC48), XP_015645028.1 (OsNAC67), XP_015623706.1 (OsNAC68) and XP_015617286.1 (OsNAC71). The Norway spruce sequences are represented by their gene model number. Black filled circles indicate subgroup III-3 Norway spruce genes for which there are both a gene model and a stress induced PUT available as indicated in the tree, grey filled circles indicate genes for which there exist only a partial PUT. Open squares indicate subgroup III-3 Norway spruce gene models for which there is no stress induced PUT available. Bootstrap values (1000 replications) are presented on the relevant nodes
