LOX2 — Phaseolus vulgaris

Summary

PHAVU_011G056500 (PvLOX2) on chromosome 11 of French bean encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase activity, also annotated for phytoene dehydrogenase, peroxidase, salicylic acid binding, and RNA cap binding functions. The protein localises to chloroplast thylakoids, stromules, stress granules, and P bodies. PvLOX2 is associated with jasmonic acid and green leaf volatile biosynthesis, oxylipin anabolism, lipid oxidation, cell redox homeostasis, and responses to herbivores, viruses, fungi, bacteria, salicylate, and jasmonic acid. It has been linked to photoperiod-sensitive flowering, seed yield, embryo development, low temperature stress, root length and thickness, and traits including insect herbivory resistance, disease resistance, UV-B tolerance, senescence, and aphid resistance. Related genes in other species are associated with wound response, herbivore defense, green leaf volatile production, and resistance to fungal pathogens and potyviruses.
