AGR — Cucumis sativus

Summary

CsAGR (CSA_4G430820) on cucumber chromosome 4 encodes a protein with auxin efflux carrier domains and exhibits both auxin influx and efflux transmembrane transporter activity, along with inositol-1,4-bisphosphate 1-phosphatase activity and phosphatidylinositol phosphate binding. The gene is associated with auxin signalling and transport pathways, including clathrin-mediated endocytosis of PIN proteins, and is linked to tropism, gravitropism, phototropism, and responses to oxidative stress and cation stress. CsAGR has been connected to numerous agronomically relevant traits, including fruit diameter, fruit length, fruit weight, leaf angle, shoot growth angle, seed set percent, heterosis, adventitious rootless, lateral root number, root phototropism, and stem senescence. It is also associated with phenotypes such as primary root growth, pollen tube growth, vein formation, and fruit seedlessness.
