CCT — Zea mays

Summary

ZM00001EB373730 (ZmCCT) on maize chromosome 9 encodes an uncharacterized protein annotated as a transcriptional co-regulator that is a component of the Mediator complex and localises to the nucleus. The gene is associated with photoperiodism and flowering time, as well as temporal regulation of development, SAM development, and the juvenile-to-adult vegetative phase transition. ZmCCT has been linked to agronomically important traits including grain yield, grain weight, ear diameter, ear length, plant height, leaf number, anthesis time, root length, heat tolerance, drought tolerance, and zinc concentration. Additional associations include carbohydrate and glucose homeostasis, cell cycle control, and systemic acquired resistance. Studies of related genes in other species link the family to flowering time, root architecture, cold response, and embryo patterning.
