LOX — Nicotiana attenuata

Summary

A4A49_16086 (LOX6) in Nicotiana attenuata encodes a lipoxygenase, a non-heme iron-containing enzyme with linoleate 13S-lipoxygenase and oxidoreductase activities, also annotated with phytoene dehydrogenase, peroxidase, salicylic acid binding, and RNA cap binding functions. The protein localises to chloroplast thylakoids, stromules, P bodies, stress granules, and the apoplast. LOX6 is associated with the lipoxygenase pathway, oxylipin, jasmonic acid, nicotine, cytokinin, and aldehyde anabolism, as well as carotenoid and chlorophyll breakdown, response to herbivores, oviposition, and cell redox homeostasis. Observed in this species, LOX2 is linked to green leaf volatile production and stress response. The gene is further associated with traits including seed yield, plant height, photosynthetic rate, leaf necrosis, photoperiod-sensitive flowering, carotenoid content, and responses to low temperature, wounding, and herbivory.
