LOX — Cucumis melo

Summary

MELO3C031048.2, the melon gene CmLOX (also known as LOX2.1, LOX3.1, LOX4, LOX6, and CmLOX2.1 through CmLOX6) on chromosome 6, encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase and phytoene dehydrogenase activities, containing lipoxygenase and an iron-binding site. This gene is associated with the lipoxygenase pathway, lipid oxidation, oxylipin and isoprenoid anabolism, green leaf volatile biosynthesis, and fatty acid anabolism. It has been connected to abscission, stomatal closure, and responses to wounding, jasmonic acid, salicylic acid, abscisic acid, salt, and other organisms. The encoded protein localizes to the chloroplast thylakoid and stroma. Additionally, CmLOX is linked to drought tolerance. Studies of related genes in other species further connect the family to these processes.
