TTG — Brassica napus

Summary

BnTTG (DARMORV10_A06P35320.1) on chromosome A06 of oilseed rape encodes a WD40-repeat protein belonging to the DCAF7-like family, with annotated molecular functions including DNA-binding transcription factor activity, protein kinase activity, and protein dimerization activity. The gene is associated with the regulation of epidermal cell fate specification, trichome morphogenesis and spacing, lateral inhibition, and pigment accumulation, particularly anthocyanin, proanthocyanidin, and flavonoid biosynthesis. It has been linked to seed coat color and mucilage defects, flower color, leaf trichome density, root hair density and length, seed weight, germination rate, and responses to biotic stress, high temperature, and auxin, brassinosteroid, and ethylene sensitivity. Localization evidence connects the product to the nucleus, cytosol, vacuole, plasmodesma, and root hair. Related genes in other species link the family to trichome and seed coat development, anthocyanin pigmentation, and root epidermal patterning.
