DESCRIPTION:Plants grow from meristems\, collections of stem cells found a
 t the apical tip of each shoot\, and at the base of each root. The shoot a
 pical meristem of flowering plants is the source all of the parts of the p
 lant found above ground\, and therefore is responsible for most of our foo
 d\, fiber\, and even atmospheric oxygen. How this collection of a few hund
 red stem cells makes\, over time\, a highly patterned plant\, with dozens 
 of cell types\, is under study. Recent investigations directed to understa
 nding the origin of the pattern of leaves around each stem in the laborato
 ry plant Arabidopsis thaliana have involved live imaging using laser scann
 ing confocal microscopy\, and computational modelling of cell-cell interac
 tions. These studies have led to a detailed model of pattern formation at 
 the shoot apex\, and to some surprises: a new class of developmental model
 \, and the discovery that leaf pattern results from feedbacks between chem
 ical signals and physical forces in growing tissues.
