LOX2 — Capsicum annuum

Summary

CaLOX2 (T459_01532) on pepper chromosome 1 encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase and oxidoreductase activities, and is also annotated with phytoene dehydrogenase, peroxidase, salicylic acid binding, and mRNA binding functions. The gene is associated with the lipoxygenase pathway, oxylipin and jasmonic acid biosynthesis, green leaf volatile production, and responses to herbivores, insects, high light, and ozone. It has been linked to anther development, filament development, photoperiodic flowering, and traits including seed yield, photosynthetic rate, root thickness, and disease tolerance. The product localizes to chloroplast thylakoids, stromules, the apoplast, stress granules, and P bodies. Studies of related genes in other species connect the family to jasmonate-mediated defense, wound response, and resistance to herbivory and necrotrophic pathogens.
