Phylogenetic tree of the WOX genes. Support values indicate: posterior probability using DNA data/bootstrap support using DNA data, on the top row and: posterior probability using protein data/bootstrap support using protein data, on the lower row. Support values are indicated on the respective branch except when the space is too limited in which case a letter indicates the branch. The tree shown was made using Bayesian inference and DNA data. The tree contains sequences from green algae (Ostreococcus tauri, Ot and O. lucimarinus, Ol), bryophytes (Physcomitrella patens, Pp), lycophytes (Selaginella moellendorffii, Sm), ferns (Ceratopteris richardii, Cr and Cyathea australis, Ca), gymnosperms (Ginkgo biloba, Gb, Gnetum gnemon, Gg, P. abies, Pa, and Pinus sylvestris, Ps), and angiosperms (A. thaliana, At, Nymphaea jamesoniana, Nj, Oryza sativa, Os, Petunia hybrida, Ph, and Vitis vinifera, Vv). The P. abies sequences are in bold.
