The eu-KAI2 and DDK super-clades diverged early in land plant evolution. Codon-level phylogenetic analysis implemented in the Genetic Algorithm for Rapid Likelihood Inference (GARLI) on the whole D14/KAI2 family (339 sequences from 143 species). This analysis was performed using an optimized character set (see Methods). Trees were rooted with charophyte sequences, consistent with contemporary notions of plant organismal phylogeny. Dotted lines indicate alternative positions for the indicated clades that would increase the parsimony of the tree. a Phylogram showing the ‘most likely’ tree from GARLI analysis, labelled to show the high-order relationships between the major clades (as described in Table 1). b Cladogram depicting the phylogenetic tree from (a) in simplified form. Major clades and sub-clades (as listed in Table 1) are collapsed. Numbers associated with internal branches denote maximum likelihood bootstrap support (percent support).
