REV1 — Cicer arietinum

Summary

LOC101491192, designated CaREV1 on chickpea chromosome 8, encodes a protein belonging to the Y-family DNA polymerase IV (UmuC) family, with nucleotidyltransferase and DNA-directed DNA polymerase activities, and is annotated for damaged DNA binding. The product localises to the nucleus and is associated with mutagenic post-replication repair, DNA repair, and response to UV-B. In chickpea, CaREV1 is linked to UV-B tolerance and to high sensitivity to UV-B, gamma rays, and DNA cross-linkers. Studies of related genes in other species connect the family to stem growth rate, germination percentage, gamma ray-induced mutagenesis, DNA damage response, and UV-induced mutagenesis, as well as to auxin content, photochemical quenching, and various climate-related traits.
