Figure 1

Phylogenetic relationships between DGAT1 and DGAT2 gene families reconstructed by the Bayesian method. A total of 151 protein sequences from eukaryotic species and 344 sites were included in the analyses. The posteriori probabilities are labeled above the branches. Only values higher than 0.5 are presented. Numbers within brackets correspond to the number of species within each group. The enzymes are represented by different colors in the phylogenetic tree: DGAT1 (red), DGAT2 (green), ACATs (purple), MGAT (dark blue) and AWAT (light blue). Taxa terminologies are abbreviated using the first letter of the genus and two letters of the species name: Alternaria brassicicola (Abr), Arabidopsis thaliana (Ath), Dictyostelium discoideum (Ddi), Euonymus alatus (Eal), Homo sapiens (Hsa), Mortierella ramanniana (Mra), Thalassiosira pseudonana (Tps), Xenopus tropicalis (Xtr).
