Summary:In embryos from af mutant females of Xenopus laevis , the cleavage furrows stayed on the surface and cytoplasmic divisions did not take place at all, while nuclear divisions continued. To gain insights into the roles of the normal product of af on early development, contractile events which have been observed in the period from fertilization until first cleavage in wild-type eggs were examined in af mutant eggs. The results indicate that the normal product of af regulates furrow-related contractile events which involve formation of the contractile ring, but exerts no effects on furrow-unrelated contractions in early Xenopus eggs.
