TT2 — Brassica oleracea var. botrytis

Summary

BoTT2 (TT2) on cauliflower chromosome 8 encodes a MYB transcription factor with DNA-binding and protein-dimerization activity. It is associated with the regulation of flavonoid, proanthocyanidin, anthocyanin, and lignin biosynthesis, as well as phenylpropanoid metabolism, jasmonic acid signaling, osmotic response, leaf morphogenesis and senescence, trichome spacing, epidermal cell fate specification, and fatty acid and green leaf volatile biosynthesis. The gene is linked to numerous traits including flavonoid and anthocyanin content, seed weight, seed coat morphology, silique morphology, leaf trichome density and morphology, stem dry weight, root epidermal cell length, iron concentration, nitrate uptake, brassinosteroid content, phototropism, flowering time, and responses to biotic, abiotic, high-temperature, and oxidative stress. It localizes to the nucleus, cytoplasm, and root hair, and is associated with MYC1.
