Cover: Stylized confocal images showing expression domains of WOX:GFP (left), FEZ:FEZ-GFP (centre) and SMB:SMB-GFP (right) in the Arabidopsis columella root cap. Roots were counterstained with propidium iodide (red) to indicate the position of cell walls; images were stylized by application of a ‘glowing edges’ filter. See Research article by Bennett et al. on p. 4055.
