LOX1 — Zea mays

Summary

ZmLOX1 (ZM00001EB144930) on maize chromosome 3 encodes a lipoxygenase with linoleate 9S- and 13S-lipoxygenase activity (EC 1.13.11.58). The protein contains Lipoxygenase and PLAT/LH2 domains and localises to the plastid and cytoplasm. This gene is associated with the lipoxygenase pathway, lipid oxidation, membrane breakdown, and regulation of signalling. It is linked to downregulation of defence response to insects, chewing, insect herbivory resistance, aphid resistance, pathogen resistance, Fusarium head blight resistance, systemic acquired resistance, and jasmonic acid-mediated defence. Associations with agronomic traits include grain number, grain yield, plant height, shoot dry weight, water use efficiency, photosynthetic rate, chlorophyll content, and salt tolerance. Additional connections include seed germination, seed aging tolerance, drought tolerance, heat tolerance, and cadmium stress response.
