CYP71C4 — Zea mays

Summary

ZM00001EB165620, also known as CYP71C4, is a maize gene on chromosome 4 that encodes a cytochrome P450 enzyme with indole-2-monooxygenase, indolin-2-one monooxygenase, and 3-hydroxyindolin-2-one monooxygenase activities, along with heme binding and oxidoreductase functions. This gene is associated with indole alkaloid and sesquiterpene biosynthetic processes, induced systemic resistance, jasmonic acid anabolism, and phloem development. It has been linked to traits including grain yield, drought tolerance, heat tolerance, and rolled leaf. The encoded protein localizes to the endoplasmic reticulum membrane. Related genes in other species suggest connections to additional monooxygenase activities, though these associations are not yet established for maize.
