AGR — Solanum tuberosum

Summary

StAGR (PGSC0003DMG400001412) on potato chromosome 2 encodes a member of the auxin efflux carrier family, with 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 potato development and linked to a wide range of biological processes including tropism, detection of oxidative stress, regulation of endocytosis, anthocyanin accumulation in response to UV light, and miRNA catabolic processes. It localizes to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated endocytic vesicles. Associations with traits include gravity response, phototropism, root length and number, seed weight, shoot branching, leaf vein morphology, and responses to blue light, manganese, and osmotic stress. Studies of related genes in other species connect the family to fruit development, shoot architecture, and root patterning.
