Abstract excerpt

The plant hormone auxin is directionally transported in plant tissues by the actions of the auxin transport proteins. PIN-FORMED (PIN) family proteins asymmetrically localize at the plasma membrane, and facilitate auxin efflux, thereby promoting cell-to-cell polar auxin transport. In previous studies, we have identified the trans-Golgi network-localized ARF GEF BEN1 (BIG5) and the Sec1/Munc18 protein BEN2 (VPS45)...
