GL3 — Daucus carota subsp. sativus

Summary

DCAR_004632 (DcGL3) on carrot chromosome 1 encodes a protein with a MYC/MYB_N domain, a bHLH domain, and HLH DNA-binding superfamily domain, annotated with DNA binding, transcription coactivator activity, and protein dimerization activity. It is associated with regulation of trichome spacing and morphogenesis, proanthocyanidin and anthocyanin anabolism, root hair development, and epidermal cell fate specification. The gene is linked to traits including leaf trichome density, root epidermal cell length, stem dry weight, seed set percent, cadmium concentration, UV light sensitivity, and plant male sterility. It localizes to the nucleus, cytoplasm, plasmalemma, and root hair. Related genes in other species are associated with trichome and root hair patterning, anthocyanin production, seed oil accumulation, and UV-B stress response.
