Phylogeny of TM3-like genes. Colours of the branches, gene names, triangle and numbers at nodes are as described in Fig. 2. Three putative subclades of TM3-like genes in Pinaceae, DAL19, DAL3 and PrMADS4, are marked by labelled lines on the right. The fully resolved phylogeny is available as Supplementary Data Fig. S13b.
