EGL1 — Brassica oleracea

Summary

BoEGL1 (BOLC102_C09P019100.1) on cabbage chromosome 9 encodes a protein with a bHLH domain, annotated with DNA-binding, transcription coactivator, protein dimerization, ubiquitin-protein transferase, and protein kinase activities. It is associated with regulation of trichome spacing, morphogenesis, and fate specification, as well as stomatal complex formation, root epidermal cell differentiation, proanthocyanidin and mucilage anabolism during seed coat development, pigmentation, and sucrose-mediated signaling. The gene has been linked to traits including leaf trichome density, seed coat color and morphology, seed weight, flavonoid content, stem dry weight, leaf elongation rate, whole plant size, germination rate, pollen fertility, male sterility, and biotic stress and insect damage responses. Related genes in other species are associated with trichome and root hair differentiation, anthocyanin and proanthocyanidin accumulation, seed coat pigmentation, and stomatal development.
