has_part mitotic spindle collapse without elongation during prophase FYPO:0002688 mitotic spindle breakage without elongation during prophase A cell phenotype in which a short mitotic spindle assembles, but does not elongate. The spindle pole bodies fail to separate, and often become spatially closer together, suggesting that the spindle shrinks. midori spindle collapse without elongation during mitotic prophase 2013-09-19T14:15:09Z mitotic spindle collapse without elongation during prophase during vegetative growth broken mitotic spindle without elongation during prophase spindle pole body convergence spindle collapse without elongation during prophase during mitotic cell cycle SPB convergence abolished mitotic spindle elongation during prophase mitotic spindle collapse
