CDC2D — Cucumis sativus

Summary

CSA_4G664480, designated CDC2D in cucumber (Cucumis sativus, chromosome 4), encodes a cyclin-dependent kinase (CDK) with serine/threonine kinase activity, RNA polymerase II CTD heptapeptide repeat kinase activity, and cyclin binding capability. This gene is associated with cell cycle control, including G1/S and G2/M transitions, mitotic entry regulation, and meiotic cell cycle modulation. It is linked to shoot apical meristem and adventitious root development, organogenesis, fruit development, abscission, auxin transport, stomatal movement, and lipid metabolism. The protein localizes to the nucleus, cytoplasm, spindle, and CDK holoenzyme complex. Trait associations include adventitious root number, root number, shoot apical meristem development, and plant height. Related genes in other species support the family’s involvement in cell cycle progression and developmental processes.
