LOX2 — Capsicum annuum

Summary

T459_08160 (LOX2/LOX3) on pepper chromosome 3 encodes a lipoxygenase enzyme with linoleate 9S- and 13S-lipoxygenase activity, peroxidase activity, and salicylic acid binding. It belongs to the lipoxygenase family and contains PLAT/LH2 and iron-binding domains. The gene is associated with the lipoxygenase pathway, jasmonic acid and oxylipin biosynthesis, green leaf volatile production, and responses to herbivores, insects, high light, and ozone. It is linked to anther development and dehiscence, filament development, photoperiodic flowering, and lignin biosynthesis. Localization evidence connects the product to chloroplast thylakoids, stromules, P bodies, stress granules, and the apoplast. Associations with pungency, seed yield, photosynthetic rate, root thickness, and low temperature stress response have been noted, as have links to wound response, cadmium and heat stress tolerance, drought resistance, herbivore resistance, and nitrogen use efficiency.
