LOX — Solanum lycopersicum

Summary

SOLYC03G122340.3 (LOX/LOXD) on tomato chromosome 3 encodes a lipoxygenase enzyme with linoleate 9S- and 13S-lipoxygenase activity, as well as peroxidase and salicylic acid binding functions. The protein localizes to chloroplast thylakoids, the apoplast, and stress granules. This gene is associated with the lipoxygenase pathway, oxylipin metabolism, and jasmonic acid biosynthesis and signaling. It has been linked to salt stress response, wound response, and defense against herbivory. Associations extend to agronomically important traits including fruit shape, carotenoid and flavonoid content, harvest index, seed yield, net photosynthetic rate, water use efficiency, and disease tolerance. Studies of related genes in other species link the family to resistance to fungal pathogens, herbivory, and jasmonate-induced defense responses.
