AGR — Solanum lycopersicum

Summary

SlAGR, encoded by tomato gene SOLYC03G118740.3 on chromosome 3, is a member of the auxin efflux carrier family and possesses auxin efflux transmembrane transporter activity, along with inositol-1,4-bisphosphate 1-phosphatase activity and phosphatidylinositol phosphate binding. The gene is associated with auxin signalling, clathrin-mediated endocytosis of PIN proteins, and regulation of seed size, reproductive structure development, and growth processes. In tomato, SlAGR has been linked to leaf flattening, flower abscission, shoot architecture, and parthenocarpic fruit development. It is also associated with numerous traits including gravity and phototropism responses, root and shoot growth angles, leaf vein morphology, fruit growth and development, stamen and anther morphology, seed set, stem diameter and senescence, petiole length, lateral root number, and responses to blue light, manganese, and herbicides. The protein localises to the auxin efflux carrier complex, basal and lateral plasma membranes, recycling endosomes, and clathrin-coated vesicles.
