title: Mitochondrial ultrastructural transformations in P. lividus eggs stimulated by ammonia.
abstract: In mitochondria of P. lividus eggs the transition from the condensed to the orthodox form is accomplished in about 45 min after fertilization. Similar ultrastructural transformations are induced by exposure to ammonia that is known to cause a partial egg activation.
