TTG — Brassica napus

Summary

BnTTG (DARMORV10_A02P40240.1) on chromosome A02 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. This gene is associated with the regulation of epidermal cell fate specification, trichome morphogenesis and spacing, root hair differentiation, 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 length and density, seed weight, germination rate, and responses to biotic stress, insect damage, high temperature, and nutrient status. Related genes in other species are associated with epidermal patterning, seed coat pigmentation, trichome development, and anthocyanin accumulation.
