Polarization of PIN3-dependent auxin transport for hypocotyl gravitropic response in Arabidopsis thaliana

[EN] 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...
