Phylogenetic tree of land plant shaggy-type kinases. Bayesian inference topology based on a curated full length amino acid sequence alignment. The tree is outgroup rooted, numbers at the nodes are posterior probabilities (in addition, bootstrap and quartet puzzling support values are shown for the four colored subfamily clades); line width also reflects support by Bayesian inference. A. thaliana SHAGGY kinases and the six T. aestivum kinases reported here are shown in red, sequences from the three eudicotyledons that have not been subjected to genome duplications beyond the γ event (C. papaya, V. vinifera and A. coerulea) are shown in cyan. For two truncated gene models excluded from the analysis the approximate position (to which clade they belong) is shown in brown.
