Phylogenetic analysis of DGAT1s. The evolutionary relationships among the 59 DGAT1s from 48 organisms were analyzed by phylogenetic analysis based on the Neighbor-Joining method of Saitou and Nei [35]. The name of each protein sequence consists of the initials of the organism followed by the assigned subfamily of DGATs in the databases and the GenBank accession number. The numbers in the parenthesis following DGAT names are the calculated distance values, which reflect the degree of divergence between all pairs of DGAT sequences analyzed. The abbreviations of the organisms are: Ac, Ajellomyces capsulatus; Ao, Arthroderma otae; At, Arabidopsis thaliana; Bb, Bubalus bubalis; Bj, Brassica juncea; Bn, Brassica napus; Bt, Bos taurus; Cf, Canis familiaris; Cv, Chlorella variabilis; Dd, Dictyostelium discoideum; Dm, Drosophila melanogaster; Dr, Danio rerio; Ea, Euonymus alatus; Ep, Echium pitardii; Gm, Glycine max; Hs, Homo sapiens; Jc, Jatropha curcas; Lj, Lotus japonicas; Ma in MaDGAT1-EFY86774.1, Metarhizium acridum; Ma in MaDGAT1-EFY97444.1, Metarhizium anisopliae; Md, Monodelphis domestica; Mm in MmDGAT1-XP_001090134.1, Macaca mulatta; Mm in MmDGAT1-NP_034176.1, Mus musculus; Mt, Medicago truncatula; Nt, Nicotiana tabacum; Oa, Ovis aries; Oc, Oryctolagus cuniculus; Oe, Olea europaea; Os, Oryza sativa; Pb, Paracoccidioides brasiliensis; Pf, Perilla frutescens; Pp in PpDGAT1-EFA85004.1, Polysphondylium pallidum; Pp in PpDGAT1-XP_001770929.1, Physcomitrella patens; Pt in PtDGAT1-XP_520014.2, Pan troglodytes; Pt in PtDGAT1a-XP_002308278.1, Populus trichocarpa; Rc, Ricinus communis; Rn, Rattus norvegicus; Sb, Sorghum bicolor; Sk, Saccoglossus kowalevskii; Sm, Selaginella moellendorffii; Ss, Sus scrofa; Tc, Tribolium castaneum; Tg, Toxoplasma gondii; Tm, Tropaeolum majus; Vf, Vernicia fordii; Vg, Vernonia galamensis; Vv, Vitis vinifera; Zm, Zea mays.
