GL3 — Daucus carota subsp. sativus

Summary

DcGL3 (DCAR_000616) on carrot chromosome 1 encodes a protein with MYC/MYB_N and bHLH domains, and is annotated with DNA binding, transcription coactivator activity, and protein dimerization activity. It is associated with regulation of trichome spacing, regulation of trichome morphogenesis, trichome density, positive regulation of anthocyanin anabolism, proanthocyanidin anabolism, plant epidermal cell fate specification, root hair development, root hair formation, root epidermal cell patterning, stomatal complex formation, and other biological processes. The gene has been linked to traits including leaf trichome density, root epidermal cell length, stem dry weight, leaf elongation rate, seed coat morphology trait, oleic acid content, cadmium concentration, UV light sensitivity, plant male sterility, and lignin biosynthesis trait. Studies of related genes in other species connect the family to trichome development, root hair patterning, anthocyanin production, seed coat development, and UV-B stress response.
