LOX — Solanum tuberosum

Summary

PGSC0003DMG400032155, designated StLOX on potato chromosome 1, encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase and phytoene dehydrogenase activities, containing the characteristic LipOase_plant and PLAT/LH2 domains. StLOX is associated with the lipoxygenase pathway, oxylipin and terpene biosynthesis, lipid oxidation, wound healing, and the induction of programmed cell death. It is linked to responses to herbivores and hormones, and localises to chloroplast thylakoids, stromules, stress granules, and the apoplast. The gene is associated with agronomically important traits including seed yield, photosynthetic rate, chlorophyll content, salt and low-temperature stress responses, and photoperiod-sensitive flowering time. Studies of related genes in other species link the family to jasmonate biosynthesis, resistance to herbivory and necrotrophic pathogens, and green leaf volatile production.
