GL3 — Brassica oleracea

Summary

BoGL3 (GL3, MYC6.2) on cabbage chromosome 4 encodes a protein with MYC/MYB_N, bHLH, and HLH domains, and is annotated with DNA binding, transcription coactivator activity, protein dimerization activity, small GTPase binding, promoter-specific chromatin binding, ubiquitin-protein transferase activity, and sequence-specific DNA binding. It is associated with trichome spacing, morphogenesis, and inhibition, root epidermal cell differentiation, stomatal complex formation, proanthocyanidin anabolism, pigmentation, and sucrose-mediated signaling. The gene is linked to leaf trichome density, seed coat color and morphology, flavonoid content, stem dry weight, shoot fresh weight, leaf elongation rate, whole plant size, plant male sterility, anther and stamen morphology, germination rate, vegetative growth time, root mass density, and biotic plant stress and insect damage response traits. Related genes in other species are linked to trichome and root hair cell differentiation, epidermal patterning, anthocyanin accumulation, seed coat pigmentation, and insect resistance.
