Polar transport of the plant hormone auxin is blocked by substances such as N-1-naphthylphthalamic acid (NPA), which inhibit auxin efflux and block polar auxin transport. To understand how auxin transport is regulated in vivo, it is necessary to discern whether auxin transport inhibitors act at the intra- or extracellular side of the plasma membrane. Populations of predominantly in-side-in plasma membrane vesicles were subjected to treatments that reverse the orientation. These treatments… CONTINUE READING
