F3H — Brassica napus

Summary

BnF3H (DARMORV10_A09P44250.1) on chromosome A09 of oilseed rape encodes a 2-oxoglutarate-dependent dioxygenase with flavanone 3-dioxygenase, flavonol synthase and chalcone isomerase activities. The gene is associated with flavonoid, anthocyanin, coumarin, lignin and phenylpropanoid biosynthesis, pigment accumulation and metabolism, seed development, and responses to UV-B, auxin and fungal molecules. It has been linked to flower, petal and seed color, anthocyanin and lignin content, respiration rate, stamen morphology, root phototropism, UV-B sensitivity, oxidative stress response, cold acclimation, photosynthetic activity, circadian clock regulation, lateral root development, genome stability, and nematode resistance. The protein localises to the tonoplast, endoplasmic reticulum, cytosol and nucleus. Related genes in other species connect the family to seed coat pigmentation, proanthocyanidin accumulation, UV-B tolerance and flavonoid production.
