title: DEK1; missing piece in puzzle of plant development.
abstract: Patterning of land plant bodies is determined by positioning of cell walls. A crucial event in land plant evolution was the ability to utilize spatial information to direct cell wall deposition. Recent studies of DEK1 in Physcomitrella patens support a role for DEK1 in position dependent cell wall orientation.
