CYP71E1 — Sorghum bicolor

Summary

SORBI_3001G018300 (CYP71E1) on sorghum chromosome 1 encodes a 4-hydroxyphenylacetaldehyde oxime monooxygenase, a cytochrome P450 family member with multiple meta-hydroxylase activities on hydroxycinnamoyl-spermidine conjugates and linoleic acid epoxygenase activity. The gene is associated with dhurrin biosynthesis, spermidine hydroxycinnamate conjugate biosynthesis, medium-chain fatty acid metabolism, detoxification, and responses to water and heat. It has been linked to pollen wall assembly, fruit ripening, and leaf dry weight. Localization evidence places the product at the endoplasmic reticulum membrane and plasmodesmata. Related genes in other species are associated with lignin content, root-knot nematode resistance, drought and cold tolerance, plant height, seed germination, and fertility traits.
