The molecular mechanisms that activate expression of zygote genes after fertilization are obscure. In animals, receptor-ligand interactions during sperm-egg membrane fusion as well as delivery of putative regulatory molecules by the sperm into the egg cytoplasm are proposed to activate zygote development and subsequent transcription of zygote genes. The mechanisms of activation of zygote development in higher plants also are mysterious, in part because of the difficulty of isolating female… CONTINUE READING
