Diversity of the TOM complex in plants. A) Schematic diagrams of the TOM complex from a selection of plant species using the TOM complex from yeast as a reference. B) A table depicting components of the TOM complex in a variety of organisms. The pink color refers to proteins that are conserved across all organisms and likely have a common ancestor. The lime green colored proteins are specific to the plant lineage. The pale green proteins are proteins that have an unknown origin. Yeast - Saccharomyces cerevisiae, Ectocarpus - Ectocarpus siliculosus (Es), Cyanidioschyzon - Cyanidioschyzon merolae (Cm), Chlorella - Chlorella variabilis (Cv), Picea - Picea glauca (Pg), Selaginella - Selaginella moellendorffii (Sm), Chlamydomonas - Chlamydomonas reinhardtii (Cr), Physcomitrella - Physcomitrella patens (Pp), Rice - Oryza sativa (Os), Arabidopsis - Arabidopsis thaliana (At), Human - Homo sapiens, Poplar -Populus tricocarpa (Pt), Glycine - Glycine max (Gm) Zea - Zea mays (Zm).
