AGR — Cucumis sativus

Summary

CsAGR (CSA_1G042820) on cucumber chromosome 1 encodes an auxin efflux carrier, possessing auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with auxin signalling, tropism, cell cycle transitions, and responses to oxidative stress, cation stress, and boron levels. It localises to the auxin efflux carrier complex, basal plasma membrane, and recycling endosome. CsAGR is linked to numerous agronomic traits including fruit length and shape, seed set, leaf vein morphology, shoot branching, lateral root number, phototropism, gravitropism, and floral organ development. Studies of related genes in other species connect the family to root patterning, vascular development, parthenocarpic fruit development, and osmotic stress tolerance.
