text: Contractile actomyosin rings drive various fundamental morphogenetic processes
ranging from cytokinesis to wound healing. Actomyosin rings are generally thought
to function by circumferential contraction. Here, we show that the spreading of
the enveloping cell layer (EVL) over the yolk cell during zebrafish gastrulation
is driven by a contractile actomyosin ring. In contrast to previous suggestions,
we find that this ring functions not only by circumferential contraction but also
by a flow-friction mechanism. This generates a pulling force through resistance
against retrograde actomyosin flow. EVL spreading proceeds normally in situations
where circumferential contraction is unproductive, indicating that the flow-friction
mechanism is sufficient. Thus, actomyosin rings can function in epithelial morphogenesis
through a combination of cable-constriction and flow-friction mechanisms.
