LOX2 — Triticum aestivum

Summary

TRAESCS5A02G007900 (symbol LOX2, also known as LOX11 or TaLOX11-5A) in bread wheat chromosome 5A encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase activity (EC 1.13.11.12), containing Lipoxygenase and PLAT/LH2 domains. The gene is associated with drought tolerance, green leaf volatile biosynthetic process, and responses to wounding, jasmonic acid, salicylate, and other organisms. It is linked to lipid oxidation, hormone metabolism, isoprenoid anabolism, fatty acid anabolism, lignin anabolism, sucrose metabolism, protein synthesis, and embryogenesis. The product localizes to chloroplast thylakoid and stroma. Associations with leaf chlorophyll content, anthesis time, and grain yield have been noted. Studies of related genes in other species link the family to crown root number, root length, aphid resistance, and jasmonic acid-mediated defense responses.
