Using a combined pharmacological and genetics approach we demonstrated that regular spacing of organs is controlled by auxin and its transporter PIN1 (Reinhardt 2000, 2003).
     
  Arabidopsis pin1 mutant. The stem grows normally but no lateral organs are formed. Right, application of a small droplet of auxin (in red) to the flank of the pin1 shoot apical meristem restores organ formation
