title: Plasmodesmata formation: poking holes in walls with ise.
abstract: Secondary plasmodesmata are cytoplasmic channels connecting adjacent plant cells that arise after cell division. How membrane-delimited channels penetrate cell walls is unknown, but now two genes, ISE1 and ISE2, are shown to be required for pathways that limit their formation.
