F3H — Brassica oleracea var. botrytis

Summary

BoF3H (BOLND125_C08P037730.1) on cauliflower chromosome 8 encodes a 2-oxoglutarate-dependent dioxygenase with flavanone 3-dioxygenase, flavonol synthase and chalcone isomerase activities. The gene is associated with anthocyanin, flavonoid and coumarin biosynthesis, pigmentation, UV-B and UV light responses, and responses to auxin and fungal molecules. Its product localises to the cytosol, endoplasmic reticulum, tonoplast and nucleus. BoF3H is linked to anthocyanin content, proanthocyanidin accumulation, seed coat colour and pigmentation, flavonol and kaempferol content, cold acclimation, oxidative stress tolerance, root phototropism, stamen morphology, respiration rate, photosynthetic activity, circadian clock regulation, genome stability, and resistance to cyst and root-knot nematodes. Studies of related genes in other species connect the family to UV-B tolerance, seed coat pigmentation, flavonoid production and glucosinolate biosynthesis.
