TTG — Brassica oleracea

Summary

BoTTG (BOLC102_C07P047940.1_BOLC102_V1) on cabbage chromosome 7 encodes a WD40-repeat domain-containing protein with DNA-binding transcription factor activity, protein kinase activity, and protein folding chaperone functions. It is associated with regulation of flavonoid, proanthocyanidin, anthocyanin, and melatonin anabolism, as well as trichome morphogenesis and spacing, root hair cell differentiation, epidermal cell fate specification, and inhibition of brassinosteroid-mediated signalling. The gene is linked to seed color and coat morphology, leaf trichome density, root hair density and length, seed weight, anthocyanin content, iron concentration, brassinosteroid content, ethylene and auxin sensitivity, and responses to biotic and abiotic stress including high temperature. Related genes in other species connect the family to seed mucilage production, tannin accumulation, and epidermal patterning.
