LOX — Nicotiana attenuata

Summary

A4A49_37784 (LOX2) in coyote tobacco (Nicotiana attenuata) encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase and phytoene dehydrogenase activities. It is associated with the lipoxygenase pathway, oxylipin and jasmonic acid anabolism, and green leaf volatile production. The gene is linked to response to herbivore, stress response, carotenoid and chlorophyll breakdown, and nicotine and cytokinin anabolism. It localizes to chloroplast thylakoids, stromules, and P bodies. Associations include leaf necrosis, seed yield, plant height, photosynthetic rate, jasmonic acid content, and responses to wounding, drought, low temperature, and cadmium stress. Related genes in other species connect the family to jasmonate signaling, defense against herbivory and necrotrophic pathogens, leaf senescence, and resistance to fungal pathogens.
