GL3 — Brassica napus

Summary

BnGL3 (GL3, DARMORV10_C04P48350.1) on chromosome C04 of oilseed rape encodes a protein with bHLH and MYC/MYB_N domains, possessing DNA binding, transcription coactivator activity, and protein dimerization activity. It is associated with trichome spacing and morphogenesis, root epidermal cell differentiation, stomatal complex formation, proanthocyanidin anabolism, and sucrose-mediated signaling. The gene is linked to numerous agronomic traits including leaf trichome density, seed coat color and morphology, flower color, stem dry weight, shoot fresh weight, flavonoid content, seed set percent, plant male sterility, germination rate, and biotic stress traits. It localizes to the nucleus, cytoplasm, plasmalemma, and mitochondria. Related genes in other species are associated with trichome and root hair cell differentiation, anthocyanin pigmentation, seed coat pigmentation, and insect resistance.
