Fig 1. Phylogenic relationships among 8 putative TaWAK6 (TraesCS5B02G063600; KR815340) homologs.

WAK6 is present uniquely in commelinids, with the exception of Aegilops tauschii and Hordeum vulgare (based on currently available genomic, transcriptomic and protein sequences). The phylogeny was reconstructed based on the amino acid sequence of kinase domains using the maximum likelihood method. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches. The tree was rooted with the sequences of two outgroup species: Oryza sativa and Brachypodium distachyon.
