IM — Cucumis sativus

Summary

CsIM (CSA_1G699560) on cucumber chromosome 1 encodes an alternative oxidase (AOX) family protein with ubiquinol:oxygen oxidoreductase, alternative oxidase, and superoxide-generating NADPH oxidase activities, and binds metal ions. It localizes to the mitochondrial inner membrane, thylakoid, and respirasome. The gene is associated with alternative respiration, photorespiration, electron transfer, metabolic burst, and responses to high light and thermal stimuli. It is linked to plastid and chloroplast organization, fruit ripening, and homeostasis, as well as metabolism of chlorophyll, carotenoids, flavonoids, proline, ethylene, carbohydrates, and nitric oxide storage. Associations include cytoplasmic male sterility, photosynthetic rate, quantum yield, chlorophyll content, stomatal resistance, stem elongation, and protein content. Related genes in other species are linked to plastoquinol oxidase activity, phytoene desaturation, chloroplast development, leaf variegation, photoprotection, and carotenoid biosynthesis.
