PLANT BIOLOGY PINning Down Auxin Flow

The plant hormone auxin regulates a variety of growth and developmental responses and must be transported within the plant in an organized fashion. Petrá $s$ ek et al. (see Brevia by Wi $s$ niewska and Perspective by Siberer and Leyser) now show, using inducible overexpression in plant cells and expression in human and yeast cells, that the protein PIN is responsible for the direction in which auxin flows out of the cell.
