CO — Daucus carota subsp. sativus

Summary

DCAR_001835 (DcCO, also known as DcFG) on carrot chromosome 1 encodes a CONSTANS-like protein containing a CCT domain and is annotated with diverse molecular functions including OGTase, peptide-O-fucosyltransferase, and histone methylase activities. The gene is associated with regulation of the phytochrome signaling pathway, photomorphogenesis, circadian clock photoentrainment and temperature compensation, flower formation, chlorophyll breakdown, and ascorbate biosynthesis. It has been linked to numerous agronomic traits including photoperiod sensitivity, vegetative vigor, leaf angle and morphology, seed protein content, iron content, tuber size, fruit set, and responses to water stress, nitrogen, nitrate, glyphosate, UV light, nematodes, and spot blotch. Related genes in other species are associated with photoperiod-dependent flowering time, heat and cadmium stress tolerance, root architecture, trichome development, disease resistance, tuberization, and seed longevity.
