abnormal septum assembly abnormal actomyosin contractile ring contraction actomyosin contractile ring contraction uncoupled from septum assembly midori actomyosin contractile ring contraction uncoupled from septum assembly during vegetative growth 2014-03-13T17:13:00Z A cell phenotype observed in the vegetative growth phase of the life cycle in which actomyosin contractile ring contraction is not spatially and temporally coupled to division septum assembly as in wild type. The edges of the growing septum and the plasma membrane do not remain in contact, and septum assembly may be slower than ring contraction. cytokinetic contractile ring contraction uncoupled from septum assembly FYPO:0003202 actomyosin contractile ring contraction uncoupled from septum assembly during mitotic cell cycle
