The Arabidopsis Receptor Kinase IRK Is Polarized and Represses Specific Cell Divisions in Roots (Developmental Cell)

Coordination of cell division across tissues and organs is fundamental to development in multicellular eukaryotes. Campos et al. identify IRK, a transmembrane receptor kinase with polar localization that negatively regulates specific cell divisions. Therefore, IRK connects signaling and cell polarity with the control of oriented cell divisions during tissue development.
