AOS — Solanum tuberosum

Summary

PGSC0003DMG400001149, the potato allene oxide synthase (AOS) gene on chromosome 11, encodes a cytochrome P450 enzyme with allene oxide synthase, colneleate synthase, and allene-oxide cyclase activities, along with heme and iron binding. This gene is associated with jasmonic acid biosynthesis and anabolism, oxylipin metabolism, and hormone anabolism. It is linked to late blight resistance and bacterial resistance. Associations also include starch yield and content, sugar content, photosynthetic rate, salt tolerance, and virus resistance. The encoded protein localizes to the chloroplast membrane, thylakoid, and plastid. Related genes in other species are linked to fungal resistance, cold tolerance, and herbivore defense.
