CKX3 — Brassica oleracea var. botrytis

Summary

BoCKX3 (CKX3) on chromosome 9 of cauliflower encodes a protein with a cytokinin dehydrogenase domain and FAD binding, and is associated with cytokinin dehydrogenase activity, FAD binding, and redox activity. The gene is associated with cytokinin metabolism, signaling, and breakdown, as well as phosphoglycerate transmembrane transport and antiporter activity. It is linked to inflorescence development, flowering time, leaf morphology, chloroplast development, and disease tolerance. Associations with phenotypes include shoot meristem activity, inflorescence meristem size, leaf and root growth, biomass production, seed yield, flower organ size, ovule formation, leaf senescence, and cadmium stress resistance. The protein is localized to plastids, chloroplast envelope, vacuole, ER, cytosol, and nucleus. Related genes in other species link the family to cytokinin level regulation and phenotypic plasticity.
