LOX1 — Capsicum annuum

Summary

CaLOX1 (T459_17447) on pepper chromosome 6 encodes a lipoxygenase with linoleate 9S- and 13S-lipoxygenase activity, containing LipOase and PLAT/LH2 domains. This gene is associated with the lipoxygenase pathway, oxylipin and jasmonic acid anabolism, lipid oxidation, membrane breakdown, and hormone metabolism. It is associated with chilling stress response, pungency, lycopene content, chlorophyll content, and photosynthetic and respiration rates. Associations include pathogen resistance, systemic acquired resistance, seed aging and germination, drought and heat tolerance, salt tolerance, oxidative stress tolerance, stomatal closure and immunity, aphid resistance, and responses to Fusarium graminearum, powdery mildew, and Cucumber mosaic virus. The gene is linked to plastid localisation. Studies of related genes in other species connect the family to fruit flavor, carotenoid content, cold tolerance, leaf senescence, and disease resistance.
