  text: Summary Gravitropism aligns plant growth with gravity. It involves gravity
    perception and the asymmetric distribution of the phytohormone auxin. Here we
    provide insights into the mechanism for hypocotyl gravitropic growth. We show
    that the Arabidopsis thaliana PIN3 auxin transporter is required for the asymmetric
    auxin distribution for the gravitropic response. Gravistimulation polarizes PIN3
    to the bottom side of hypocotyl endodermal cells, which correlates with an increased
    auxin response at the lower hypocotyl side. Both PIN3 polarization and hypocotyl
    bending require the activity of the trafficking regulator GNOM and the protein
    kinase PINOID. Our data suggest that gravity-induced PIN3 polarization diverts
    the auxin flow to mediate the asymmetric distribution of auxin for gravitropic
    shoot bending.
