CO — Daucus carota subsp. sativus

Summary

DCAR_007535, designated DcCO on carrot chromosome 2, encodes a CONSTANS-like protein containing B-box and CCT domains. The gene is associated with regulation of phytochrome signaling pathway, upregulation of chlorophyll breakdown, upregulation of short-day photoperiodism, flowering, response to long-day, response to short-day, flower formation, photoentrainment of circadian clock, and other biological processes. DcCO is linked to numerous traits including photoperiod sensitivity, vegetative vigor, leaf angle, seed protein content, iron content, water stress response, and nitrogen sensitivity. Studies of related genes in other species link the family to photoperiod-dependent flowering time, tuberization, stress tolerance, and root architecture.
