aAbbreviations: Phatr, Phaeodactylum tricornutum; Arath, Arabidopsis thaliana; Ostta, Ostreococcus tauri; Sacce, Saccharomyces cerevisiae; Homsa, Homo sapiens. bData taken from [67]. cData taken from [30].dOne of these genes shows some CDKB characteristics. eClassification uncertain because of weak phylogeny. NA, not available due to other classification nomenclature.
