TTG — Brassica oleracea var. botrytis

Summary

BoTTG (BOLND125_C07P045480.1_BOLND125_V1) on cauliflower chromosome 7 encodes a WD40-repeat domain-containing protein with DNA-binding transcription factor activity, protein kinase activity, and protein dimerization activity. It is associated with the regulation of epidermal cell fate specification, trichome morphogenesis and spacing, root hair differentiation, flavonoid and anthocyanin metabolism, proanthocyanidin biosynthesis, pigmentation, and brassinosteroid signalling inhibition. The gene is linked to seed color and coat morphology, leaf trichome density, root hair density and length, seed weight, anthocyanin content, iron concentration, ethylene and auxin sensitivity, and responses to biotic stress, insect damage, and high and low temperature stress. It localises to the nucleus, cytosol, plasmalemma, vacuole, and plasmodesmata. Related genes in other species are linked to seed coat pigmentation, trichome development, and root epidermal patterning.
