Phylogenetic analysis of APO-like proteins in seven species. These proteins are mainly clustered into six groups annotated clockwise in red (group 1), maroon (group 2), fuchsia (group 3), blue (group 4), aqua (group 5), and green (group 6). Cluster analysis was conducted using MEGA4. APO, apolipoprotein; ath, Arabidopsis thaliana; cel, Caenorhabditis elegans; cre, Chlamydomonas reinhardtii; ddi, Dictyostelium discoideum; dme, Drosophila melanogaster; hsa, Homo sapiens; OLEO, oleosin; rha, Rhodococcus sp. RHA1. The sequences and names of proteins are downloaded from KEGG database (106).
