Phylogenetic trees of the protein sequences of the DHPS domain constructed using maximum likelihood method Phyml (see text). The selected model using Bayesian information criterion was LG + G + I with gamma shape parameter estimate = 1.058 and the proportion of invariable site estimate = 0.047. Nodes values represents the Bayesian posterior probabilities branch support. The species colour code corresponds to the type of plastid pigments, as follows: purple, chlorophyll a; green, chlorophyll a and b; and red, chlorophyll a and c.
