Spatial positioning of the division plane in plant cells is determined premitotically by the preprophase band of microtubules. Spinner et al. show that its formation in Arabidopsisrequires a PP2A complex containing FASS and TON1 which is recruited to cortical microtubules by the TRM protein family.
