LOX1 — Zea mays

Summary

ZM00001EB206040 (ZmLOX1, also known as LOX8 or ZmLOX2) on maize chromosome 4 encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase and oxidoreductase activities. This gene is associated with lipid oxidation, jasmonic acid metabolism, phytoalexin biosynthesis, and response to herbivore. It has been linked to regulation of photosynthesis, cell redox homeostasis, nitrogen compound transport, and sex determination. ZmLOX1 is associated with agronomic traits including grain yield, seed yield, shoot fresh weight, shoot dry weight, root length, root thickness, plant height, leaf size, cold tolerance, drought tolerance, and photoperiod-sensitive flowering time trait. The encoded protein localizes to chloroplast thylakoid, stromule, stress granule, and apoplast. Studies of related genes in other species link the family to insect resistance, disease resistance, jasmonate signaling, wound response, and green leaf volatile production.
