AGR — Solanum tuberosum

Summary

PGSC0003DMG400018745 (AGR, also known as pin2) on potato chromosome 7 encodes an auxin efflux carrier, a member of the PIN family of transmembrane transporters. The product exhibits auxin efflux and influx transporter activities, binds multiple phosphoinositides and clathrin, and acts as a protein phosphatase regulator. In potato, the gene is associated with development. It is associated with gravitropism, phototropism, root and shoot growth, branching, vein formation, pollen tube growth, seed set, and responses to oxidative stress, boron, and blue light. Associations also include adventitious root length, root number, seed weight, stem senescence, herbicide sensitivity, and leaf and stamen morphology. The protein localizes to the plasma membrane, endosomes, and auxin efflux carrier complexes, and participates in auxin transport, gravity sensing, and hormone signaling pathways.
