F5H — Brassica napus

Summary

BnF5H (DARMORV10_C01P02720.1) on oilseed rape chromosome C01 encodes a cytochrome P450 family 84A protein with ferulate 5-hydroxylase activity, also annotated as a monooxygenase and oxidoreductase that binds iron and heme. The gene is associated with lignin anabolism, phenylpropanoid metabolism, cell wall modification, cutin and very-long-chain fatty acid anabolism, terpenoid and sesquiterpene biosynthesis, chlorophyll anabolism and its downregulation, response to UV-B, fruit ripening, and defense response. It localises to the endoplasmic reticulum and plasma membrane. Associations include stem strength, drought tolerance, root morphology, lateral root development, lignin composition and monomer content, syringyl lignin biosynthesis, sinapine content, cell wall digestibility and saccharification efficiency, sugar release, plant growth, and disease resistance. Studies of related genes in other species link the family to biomass yield, male sterility, and altered phenylpropanoid metabolism.
