AGR — Solanum tuberosum

Summary

StAGR (PGSC0003DMG400030495) on potato chromosome 5 encodes a protein with auxin efflux carrier domains and annotated molecular functions including auxin efflux and influx transmembrane transporter activities, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. The gene is associated with auxin signalling, transport, and metabolism, and with processes such as tropism, endocytic recycling, anthocyanin accumulation in response to UV light, and detection of oxidative stress. It has been linked to traits including root length, gravity response, phototropism, seed weight, shoot branching, leaf vein morphology, and brassinosteroid content. Phenotypic associations in potato include potato development, and studies of related genes in other species connect the family to fruit development, root patterning, and shoot architecture.
