AGR — Solanum lycopersicum

Summary

SlAGR (SOLYC10G078370.2) encodes a protein with auxin efflux carrier activity, belonging to the auxin efflux plant domain family and also annotated with inositol-1,4-bisphosphate 1-phosphatase activity, phosphatidylinositol phosphate binding, and clathrin binding. This tomato gene on chromosome 10 is associated with auxin efflux transport, gravitropism, and phyllotactic patterning. It has been linked to leaf flattening, flower abscission, shoot architecture, and parthenocarpic fruit development in tomato. Associations include gravity response, root and shoot growth traits, leaf angle, seed set, stamen and anther morphology, phototropism, and herbicide sensitivity. The gene is associated with auxin signalling, clathrin-mediated endocytosis of PIN proteins, and regulation of seed size. Studies of related genes in other species link the PIN family to root patterning, embryonic development, flowering time, osmotic stress tolerance, and biomass production.
