Abstract

Summary: The 2–oxoglutarate‐dependent dioxygenase (2 OGD) superfamily is the second largest enzyme family in the plant genome, and its members are involved in various oxygenation/hydroxylation reactions. Despite their biochemical significance in metabolism, a systematic analysis of plant 2 OGD s remains to be accomplished. We present a phylogenetic classification of 479 2 OGD s in six plant models, ranging from green algae to angiosperms. These were classified into three classes –DOXA,DOXB and DOXC– based on amino acid sequence similarity. The DOXA class includes plant homologs ofE scherichia coli A lk B, which is a prototype of 2 OGD involved in the oxidative demethylation of alkylated nucleic acids and histones. The DOXB class is conserved across all plant taxa and is involved in proline 4–hydroxylation in cell wall protein synthesis. The DOXC class is involved in specialized metabolism of various phytochemicals, including phytohormones and flavonoids. The vast majority of 2 OGD s from land plants were classified into the DOXC class, but only seven fromC hlamydomonas, suggesting that this class has diversified during land plant evolution. Phylogenetic analysis assigned DOXC‐class 2 OGD s to 57 phylogenetic clades. 2 OGD genes involved in gibberellin biosynthesis were conserved among vascular plants, and those involved in flavonoid and ethylene biosynthesis were shared among seed plants. Several angiosperm‐specific clades were found to be involved in various lineage‐specific specialized metabolisms, but 31 of the 57 DOXC‐class clades were only found in a single species. Therefore, the evolution and diversification of DOXC‐class 2 OGD s is partly responsible for the diversity and complexity of specialized metabolites in land plants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
