TTG — Brassica napus

Summary

BnTTG (DARMORV10_A02P40280.1) on chromosome A02 of oilseed rape encodes a WD40 repeat-containing protein belonging to the DCAF7-like family, annotated with DNA-binding transcription factor activity, protein kinase activity, and protein folding chaperone functions. The gene 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. It is linked to seed coat color and mucilage traits, flower color, leaf trichome density, root hair density and length, seed weight, germination rate, brassinosteroid and auxin sensitivity, iron concentration, and responses to biotic stress, high temperature, and other abiotic stresses. Studies of related genes in other species connect the family to epidermal patterning, seed coat pigmentation, and trichome development.
