Role of the Arabidopsis PIN6 auxin transporter in auxin homeostasis and auxin-mediated development.

Plant-specific PIN-formed (PIN) efflux transporters for the plant hormone auxin are required for tissue-specific directional auxin transport and cellular auxin homeostasis. The Arabidopsis PIN protein family has been shown to play important roles in developmental processes such as embryogenesis, org...
