Katanin severs microtubules to facilitate array reorientation and amplification. Here the authors show that a conserved centrosomal complex of Msd1 and Wdr8 recruits katanin to cortical nucleation sites in acentrosomal plant cells and stabilizes daughter microtubules until they are severed by katanin.
