title: Traffic control in the root: keeping root branching in check.
abstract: While the importance of intercellular communication in plants is well documented, the role of symplastic transport during the formation of new meristems in roots has remained unexplored. In this issue of Developmental Cell, Benitez-Alfonso et al. (2013) show that callose-dependent cell-to-cell connectivity determines root branching in Arabidopsis thaliana.
