AGR — Solanum lycopersicum

Summary

SlAGR (SOLYC06G059730.3) on tomato chromosome 6 encodes a protein with auxin efflux carrier activity, belonging to the auxin efflux carrier family and the membrane transporter superfamily. It also exhibits inositol-1,4-bisphosphate 1-phosphatase activity, 3'(2'),5'-bisphosphate nucleotidase activity, and binds various phosphatidylinositol phosphates and clathrin. The gene is associated with auxin efflux carrier complex localization, recycling endosomes, and basal plasma membrane. It is linked to leaf flattening, flower abscission, shoot architecture, and parthenocarpic fruit development in tomato. Associations include gravity response, phototropism, root growth, lateral root number, seed set, leaf angle, stem diameter, adventitious root formation, and responses to blue light, manganese, and herbicides. Studies of related genes in other species connect the family to root patterning, gravitropism, phototropism, vascular development, and osmotic stress tolerance.
