EGL1 — Brassica oleracea var. botrytis

Summary

BoEGL1 (EGL1) on cauliflower chromosome 9 encodes a protein with a bHLH domain, classified as a MYC/MYB_N family protein, and exhibits DNA binding, transcription coactivator activity, protein dimerization activity, and ubiquitin-protein transferase activity. It is associated with regulation of trichome spacing, morphogenesis, and fate specification, as well as proanthocyanidin anabolism, stomatal complex formation, root epidermal cell differentiation, and pigmentation. The gene is linked to traits including leaf trichome density, seed coat color, flavonoid content, stem dry weight, seed weight, germination rate, plant male sterility, and biotic plant stress trait. It localizes to the nucleus, cytoplasm, plasmalemma, and vesicles. Related genes in other species are associated with trichome and root hair cell differentiation, anthocyanin accumulation, and seed coat pigmentation.
