AGR — Solanum lycopersicum

Summary

SlAGR (SOLYC10G080880.2) on tomato chromosome 10 encodes a protein with auxin efflux carrier domains and multiple annotated molecular functions, including auxin influx and efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with auxin signalling, transport, and metabolism pathways, as well as clathrin-mediated endocytosis of PIN proteins and gravitropism. In tomato, it has been linked to leaf flattening, flower abscission, shoot architecture, and parthenocarpic fruit development. Broader associations include gravity response, phototropism, root and shoot growth traits, seed set, leaf angle, stem diameter, and responses to blue light, osmotic stress, and herbicides. The gene product localises to the auxin efflux carrier complex, plasma membrane, and recycling endosome, and is associated with regulation of secretion and cellular responses to pH and oxidative stress.
