Phylogenetic analyses of anciently acquired genes. Numbers above the branch show bootstrap values from maximum likelihood and distance analyses, and posterior probabilities from Bayesian analyses, respectively. Asterisks indicate values lower than 50%. Colors show taxonomic affiliations. (a) MGDG synthase; (b) dihydrodipicolinate reductase (dapB); (c) diaminopimelate decarboxylase (lysA); (d) dihydrodipicolinate synthase (dapA). DapA, dapB and lysA are related to lysine biosynthesis in plants. Please note in (d) that green plant and glaucophyte sequences are of γ-proteobacterial origin whereas the red alga Cyanidioschyzon retains the cyanobacterial (plastidic) copy. The Dehalococcoides sequence in the cyanobacterial cluster in (d) was likely acquired from cyanobacteria. Another gene (aspartate aminotransferase) related to lysine biosynthesis in plants was likely acquired from chlamydiae [19]. Also see the text and Additional data file 1 for more discussion.
