AGR — Solanum tuberosum

Summary

StAGR (PGSC0003DMG400030755) on potato chromosome 6 encodes a protein with auxin efflux carrier and auxin influx transmembrane transporter activities, as well as inositol-1,4-bisphosphate 1-phosphatase activity, 3'(2'),5'-bisphosphate nucleotidase activity, and binding affinities for various phosphatidylinositol phosphates and clathrin. The gene is associated with potato development, tropism, anthocyanin accumulation in response to UV light, detection of oxidative stress, regulation of endocytosis, and miRNA catabolic processes. It localizes to the auxin efflux carrier complex, recycling endosome, and basal plasma membrane. Associations include traits such as adventitious root length, gravity response, phototropism, seed weight, shoot growth angle, leaf vein morphology, and responses to blue light, manganese, and osmotic stress. Related genes in other species are linked to root patterning, fruit development, flowering time, and stress tolerance.
