Evolutionary events of the AHL gene family in land plants. Numbers of gene duplication (shown in blue after "+") and loss (shown in red after "-") events were inferred for each internal node as well as for current extant species. The numbers of the AHL genes were also listed accordingly. The red star denotes when the AHL genes emerged. Al, Arabidopsis lyrata. At, Arabidopsis thaliana. Bd, Brachypodium distachyon. Bra, Brassica rapa. Cpa, Carica papaya. Cs, Cucumis sativus. Gm, Glycine max. Mdp, Malus domestica. Mes, Manihot esculenta. Mt, Medicago truncatula. Os, Oryza sativa. Pp, Physcomitrella patens. Ppa, Prunus persica. Pt, Populus trichocarpa. Rc, Ricinus communis. Sb, Sorghum bicolor. Sm, Selaginella moellendorffii. Vv, Vitis vinifera. Zm, Zea mays. A, Angiosperms. B, Brassicaceae. Em, Embryophyta. Eu, Eudicots. F, Fabidae (Eurosids I). G, Grasses. Mp, Malpighiales. Mv, Malvidae (Eurosids II). NF, Nitrogen fixing. T, Tracheophyta (vascular plants).
