Polarity is a fundamental property of all cells. The molecular mechanisms that underlies the establishment and maintenance of cellular polarity have been intensively studied in animal cells and yeast-like fungi. These studies reveal an emerging general principle whereby positional information is relayed to the cytoskeleton and other morphogenetic functions by conserved signaling pathways. Comparatively less attention has been directed toward the molecular basis of polarized growth in plant cells and tissues. This volume, Polarity in Plants, provides a comprehensive review of the topic that should satisfy both hardcore aficionados of plant cell and developmental biology as well as curious investigators interested in drawing comparisons to animal and fungal systems.
