Dans les cellules eucaryotes, la division cellulaire nécessite l'assemblage d'une structure bipolaire complexe appelée fuseau mitotique. L'assemblage de ce fuseau est initié par la nucléation de microtubules. Dans les cellules méiotiques de vertébrés, lesHigher plant cells are characterized by dispersed microtubule organizing centers. During interphase, they were identified at the nuclear surface, close to the cortex and along pre-existing microtubules. However, the mechanisms of spindle microtubule asse
