DES — Solanum tuberosum

Summary

PGSC0003DMG400025158, designated DES (also known as AOS3, DES1, StHPL, StDES1, HPL, and StAOS3) on potato chromosome 1, encodes a divinyl ether synthase belonging to the cytochrome P450 family. The enzyme exhibits colneleate synthase, allene oxide synthase, allene-oxide cyclase, lyase, monooxygenase, and oxidoreductase activities, binding iron and heme. This gene is associated with the lipoxygenase pathway, oxylipin metabolism and anabolism, jasmonic acid anabolism, fatty acid metabolism, regulation of hormone levels, systemic acquired resistance, innate immunity, fruit ripening, seed germination, cell death, and responses to abiotic stimuli. It has been linked to alpha-ketol formation, net photosynthetic rate, photochemical quenching, starch content, jasmonic acid content, and arbuscular mycorrhizal fungal colonization. The encoded protein localizes to the chloroplast membrane, inner membrane, thylakoid membrane, and envelope, as well as the cytosol.
