ABP1/ABL3-TMK1 cell-surface auxin signaling targets PIN2-mediated auxin fluxes for root gravitropism In gravistimulated roots, gravity perception in the columella redirects the flow of the plant hormone auxin toward the lower root side, where it inhibits cell elongation for downward root bending. Thi...

It is out! A tandem of two papers showing TMK regulation of PIN-dependent auxin transport www.cell.com/cell/fulltex... (PIN2, Friml lab) and www.cell.com/developmenta... (PIN1, Xu lab)
