LOX — Solanum lycopersicum

Summary

SlLOX, a tomato lipoxygenase gene on chromosome 12, encodes a protein with linoleate 13S-lipoxygenase and oxidoreductase activities, containing the conserved lipoxygenase domain and iron-binding site. The gene is associated with the lipoxygenase pathway, oxylipin metabolism, and fatty acid oxidation, and has been linked to salt stress response in tomato. It is also associated with traits including jasmonic acid content, carotenoid content, photosynthetic rate, harvest index, seed yield, germination rate, and responses to low temperature and wounding. The encoded protein localizes to chloroplast thylakoids, stromules, and stress granules. Studies of related genes in other species link the lipoxygenase family to jasmonate biosynthesis, defense against herbivory, resistance to fungal pathogens, and stomatal closure.
