Figure 2

The WOX13 Orthology Group. The different elements of the figure are described from the left to the right. 1) The neighbor-joining tree of the WOX proteins from the WOX13 Orthology Group (see material and methods). The tree topology, the significance of the nodes, and the bootstrap values displayed are the same as in Figure 1. The scale at the top left corner indicates 0.05 substitutions per site. 2) The motif composition of each protein is denoted by colored boxes on a bar representing the length of the protein and aligned on the WOX homeodomain (displayed in orange). Species names, in alphabetic order, are: Afo: Aquilegia formosa; AT: Arabidopsis thaliana; Bna: Brassica napus; Bra: Brassica rapa; Ccl: Citrus clementina; Csi: Citrus sinensis; Cte: Citrus temple; Ees: Euphorbia esula; Ghi: Gossypium hirsutum; Gma: Glycine max; Gra: Gossypium raimondii; Han: Helianthus annuus; Hvu: Hordeum vulgare; Les: Lycopersicon esculentum; Lja: Lotus japonicus; Lsa: Lactuca sativa; Lvi: Lactuca virosa; Mdo: Malus domestica; Mtr: Medicago truncatula; OS: Oryza sativa; OT: Ostreococcus tauri; Ppa: Physcomitrella patens; Psi: Picea sitchensis; Pta: Pinus taeda; Ptr: Populus tremula × Populus tremuloides; Pvu: Phaseolus vulgaris; Stu: Solanum tuberosum; Vvi: Vitis vinifera; Zma: Zea mays. The color code of the different motifs is described at the bottom of the figure.
