CYP89 — Brachypodium distachyon

Summary

BRADI_3G17090V3 (CYP89, BdCYP89) on chromosome 3 of Brachypodium distachyon encodes a cytochrome P450, a member of the plant metabolite P450 family. The encoded protein is associated with multiple monooxygenase activities, including flavonoid 3',5'-hydroxylase, flavonoid 3'-monooxygenase, indolin-2-one monooxygenase, and fluorescent chlorophyll catabolite deformylase activity, and binds heme and iron. It is associated with chlorophyll a breakdown, flavonoid anabolism, response to herbivore, and regulation of timing of plant organ formation. The protein localizes to the endoplasmic reticulum membrane, mitochondria, and cytosol. Studies of related genes in other species connect the CYP89 family to drought tolerance, plant height, root morphology, days to flowering, and cytokinin content.
