thick actin cables thick actin cables in medial region midori thick actin cables in medial region during vegetative growth Cells with this phenotype usually have thick actin cables instead of a well-formed contractile ring near the midpoint of the cell, when the ring would normally form and contract during cytokinesis. thick actin cables in medial region of cell thick actin cables in medial region during mitotic cell cycle thick formin-nucleated actin cables in medial region FYPO:0006308 2017-12-12T14:49:31Z increased actin cable thickness in medial region A physical cellular phenotype observed in the vegetative growth phase of the life cycle in which cells form actin cables that are thicker than normal in the medial region of the cell.
