Awakening of the Invertebrate Egg at Fertilization

  • Bennett M. Shapiro

Abstract

The previous chapter dealt with mechanisms by which the invertebrate sperm responds to the egg, first undergoing the acrosome reaction and then binding to it before gamete membrane fusion. The fusion of sperm and egg is catastrophic for both the organism and the species. A new individual is formed with a reassortment of meiotic products that constitutes a new roll of the evolutionary dice. The mechanism of formation of the zygote has received increasing attention over the past decade with the application of modern techniques in molecular and cellular biology. In this chapter I will focus on some recent insights concerning several phenomena associated with activation of the sea urchin egg after fertilization. Work in this field occurs in the context of an excellent scientific literature that dates back well over a century; I shall try to point out some of the classical antecedents of the modern study of fertilization mechanisms.
