AGR — Cucumis sativus

Summary

CsAGR (CSA_2G074260) on cucumber chromosome 2 encodes a member of the auxin efflux carrier family, with annotated molecular functions including auxin efflux and influx transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with diverse biological processes such as tropism, detection of oxidative stress, phosphoinositide-mediated signaling, anthocyanin accumulation in response to UV light, and regulation of endocytosis and cell wall organization. It localizes to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated vesicles. The gene is linked to numerous agronomically relevant traits including fruit length, seed set percent, leaf vein morphology, shoot growth angle, lateral root number, root hair length, phototropism, gravitropism, and responses to blue light, manganese, and osmotic stress. Studies of related genes in other species connect this family to fruit development, root patterning, and shoot architecture.
