OEX1 — Brassica oleracea

Summary

BoOEX1, encoded by gene BOLC102_C08P037630.1 on cabbage chromosome 8, is a 5'-3' exonuclease and flap endonuclease with DNA-directed DNA polymerase activity, DNA-binding transcription factor activity, and protein dimerization activity. It is associated with head development, DNA replication and Okazaki fragment processing, pigmentation, anthocyanin and glucosinolate metabolism, chlorophyll anabolism, sulfur metabolism, response to low humidity and stress, guard cell fate commitment and differentiation, stomatal development, myrosin cell development, cell growth, morphogenesis, and NO storage. The gene is linked to leaf color, chlorophyll content, and heterosis, as well as immunity to Botrytis cinerea. Its product localizes to the nucleus and mitochondria. Related genes in other species are linked to root gravitropism.
