HPL — Cucumis sativus

Summary

CsHPL (CSA_7G041960) on cucumber chromosome 7 encodes a 13-hydroperoxide lyase, a cytochrome P450 family IV enzyme with colneleate synthase, allene oxide synthase, allene-oxide cyclase, lyase, monooxygenase, and oxidoreductase activities, and binds iron and heme. The gene is associated with the lipoxygenase pathway, oxylipin and jasmonic acid biosynthesis, fatty acid metabolism, immune response, fruit development and ripening, and defense and wound responses. It is linked to chloroplast membranes and the cytosol. Associations include linoleic acid content, susceptibility to Pseudomonas syringae, C6 volatile production, arabidopside accumulation, volatile synthesis, and hexenal signaling. Studies of related genes in other species connect the family to fruit aroma, green leaf volatile biosynthesis, and resistance to aphids and herbivores.
