Overview of the number of FAP homologs and other GMC oxidoreductases identified in eukaryotic algae and other bikonts. In most groups, there is one FAP and no other GMC oxidoreductase. Remarkable species whose number of FAP or other GMC oxidoreductases depart from this rule are listed individually. Hyphens indicate that no protein could be identified by BLAST searches. A widely accepted phylogeny of the Bikonta is used. The dashed line connects the tree of the Bikonta to the rest of the phylogenetic tree of the Eukaryotes. Photosynthetic groups or species are colored. Rounds correspond to endosymbiosis: blue round with one black circle, primary endosymbiosis; green and red rounds with two black circles, secondary endosymbiosis; red round with three black circles is for tertiary endosymbiosis in some (not all) Dinophyta; red or green rounds indicate red or green plastid origin, respectively; n: nucleomorph; x: secondary plastid loss.
