DES — Nicotiana attenuata

Summary

A4A49_28468 (DES, also known as AOS3) in Nicotiana attenuata on chromosome 1 encodes a cytochrome P450 enzyme with allene oxide synthase, colneleate synthase, allene-oxide cyclase, lyase, monooxygenase, and oxidoreductase activities, and binds iron and heme. The protein localizes to the chloroplast inner membrane, thylakoid membrane, and envelope, as well as the cytosol. It is associated with oxylipin and jasmonic acid biosynthesis, fatty acid metabolism, jasmonic acid signaling, sterol metabolism, defense response, and response to wounding. The gene is linked to photosynthetic rate and arbuscular mycorrhizal fungal colonization. Studies of related genes in other species connect the family to traits including relative yield, fruit flavor, linoleic acid content, root volume, seed coat color, starch content, sugar content, jasmonic acid content, and net photosynthetic rate.
