LOX — Solanum lycopersicum

Summary

SlLOX, the tomato lipoxygenase gene on chromosome 5, encodes a protein with linoleate 13S-lipoxygenase activity and domains characteristic of plant lipoxygenases. It is associated with the lipoxygenase pathway, oxylipin metabolism, and fatty acid oxidation, and has been linked to salt stress response in tomato. The gene product localises to chloroplast thylakoids, stromules, and stress granules. SlLOX is associated with plant fresh weight, harvest index, seed yield, carotenoid content, photosynthetic rate, jasmonic acid content, and responses to low temperature and wounding. Related genes in other species are linked to jasmonate biosynthesis, resistance to herbivory and necrotrophic pathogens, and stomatal closure.
