GL3 — Cucumis sativus

Summary

CsGL3 (CSA_6G409990) encodes a MYC/MYB_N domain-containing protein with DNA binding, transcription coactivator activity, and protein dimerization activity. In cucumber, this gene is associated with the regulation of trichome spacing and morphogenesis, flavonoid and anthocyanin anabolism, proanthocyanidin anabolism, and epidermal cell fate specification. It has been linked to traits including leaf trichome density, stem dry weight, root epidermal cell length, seed coat morphology, oleic acid content, cadmium concentration, UV light sensitivity, and plant male sterility. The gene is also associated with root hair development, trichome patterning, and endoreduplication. Studies of related genes in other species link the family to trichome and root hair development, anthocyanin production, seed oil accumulation, and UV-B stress tolerance.
