cytoplasmic microtubule formation from nuclear microtubules cytoplasmic microtubule formation from nuclear microtubules following spindle microtubule fragmentation A cellular process phenotype observed in the vegetative growth phase of the life cycle in which cytoplasmic microtubules are formed by the extension of existing nuclear microtubules arising from fragmentation of the mitotic spindle. Normally, cytoplasmic microtubules are nucleated from microtubule organizing centers in the cytoplasm. cytoplasmic microtubule formation from nuclear microtubules following mitotic spindle microtubule fragmentation midori FYPO:0004729 2015-07-27T13:40:38Z cytoplasmic microtubule formation from nuclear microtubules following spindle microtubule fragmentation during mitotic cell cycle cytoplasmic microtubule formation from nuclear microtubules following spindle microtubule fragmentation during vegetative growth
