TTG — Brassica napus

Summary

BnTTG (DARMORV10_C02P60240.1) on chromosome C02 of oilseed rape encodes a DCAF7-like protein with DNA-binding transcription factor activity, protein kinase activity, and protein dimerization activity. It is associated with the regulation of epidermal cell fate specification, trichome morphogenesis and spacing, root hair differentiation, and pigment accumulation including anthocyanin, proanthocyanidin, and flavonoid biosynthesis. The gene is linked to seed coat color and mucilage defects, flower color, leaf trichome density, root hair length and density, seed weight, germination rate, and responses to auxin, brassinosteroids, ethylene, jasmonic acid, and high temperature stress. Studies of related genes in other species connect the family to trichome and seed coat development, anthocyanin pigmentation, and root epidermal patterning.
