LOX1 — Zea mays

Summary

ZmLOX1 (LOX1) on maize chromosome 5 encodes a lipoxygenase with linoleate 9S- and 13S-lipoxygenase activity, containing lipoxygenase and PLAT/LH2 domains. It is associated with the lipoxygenase pathway, lipid oxidation, jasmonic acid anabolism, and responses to insects and pathogens. It is also linked to sex determination, pigment accumulation, nitrogen compound transport, gluconeogenesis, sucrose metabolism, and detoxification. The protein localizes to the plastid and cytoplasm. Associations include plant height, photosynthetic rate, sugar content, seed germination and aging tolerance, drought and heat tolerance, stomatal closure, and resistance to Fusarium head blight, aphids, and Cucumber mosaic virus. Studies of related genes in other species connect the family to leaf senescence, seed longevity, root development, and stress tolerance.
