AGR — Solanum lycopersicum

Summary

SlAGR (SOLYC07G006900.2) on tomato chromosome 7 encodes a protein with auxin efflux carrier and transmembrane transporter activity, also annotated with inositol-1,4-bisphosphate 1-phosphatase activity and phosphatidylinositol phosphate binding. The gene is associated with auxin efflux transport, gravitropism, and hormone signaling pathways. 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, fruit development, seed set, leaf vein morphology, and responses to radiation, manganese, and blue light. The gene is also connected to auxin homeostasis, lateral root organogenesis, pollen tube growth, vascular development, and wound response. Related genes in other species are linked to embryonic patterning, root meristem growth, flowering time, osmotic stress tolerance, and biomass production.
