TTG — Brassica napus

Summary

BnTTG (DARMORV10_C07P43200.1) on chromosome C07 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, pigment accumulation, and proanthocyanidin and anthocyanin biosynthesis. It is linked to traits such as seed coat color and morphology, flower color, leaf trichome density, root hair density and length, seed weight, germination rate, flavonoid content, brassinosteroid and auxin content and sensitivity, iron concentration, lignin content, and responses to biotic stress, high temperature, and other abiotic stresses. Related genes in other species link the family to trichome and seed coat development, anthocyanin pigmentation, and root epidermal patterning.
