has_part inheres_in abnormal cytokinesis during vegetative growth premature actomyosin contractile ring disassembly premature mitotic contractile ring disassembly midori abnormal contractile ring contraction with contractile ring collapse actomyosin contractile ring collapse A cytokinesis phenotype observed in the vegetative growth phase of the life cycle in which the contractile ring collapses or disassembles upon initiation of contraction during anaphase B. Septum formation typically does not occur in cells in which the contractile ring has collapsed. premature cytokinetic contractile ring disassembly premature actomyosin contractile ring disassembly during mitotic cell cycle advanced actomyosin contractile ring disassembly FYPO:0001904 actomyosin contractile ring disassembly before septation unstable actomyosin contractile ring actomyosin contractile ring collapse upon contraction premature actomyosin contractile ring disassembly during vegetative growth unstable actomyosin ring 2013-01-30T17:33:34Z cytokinesis defects, collapse of the actinomyosin ring abnormal actomyosin contractile ring organization
