has_part inheres_in abnormal cytokinesis during vegetative growth decreased rate of medial membrane band assembly decreased rate of medial membrane band formation A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the rate, or speed, of medial membrane band assembly is decreased. Medial membrane band assembly is the assembly of a sterol-rich region of the plasma membrane at the cell surface overlying the contractile ring. decreased rate of medial membrane band assembly during vegetative growth midori reduced rate of medial membrane band assembly FYPO:0005874 2016-12-16T14:05:27Z decreased rate of medial membrane band assembly during mitotic cell cycle
