Study on the Relationship between Embryo Genesis and Isozymes Divergence in Doritis pulcherrima Lindl.

Isozyme divergence was studied during the period of embryo genesis in Doritis pulcherrima Lindl.Some isozyme loci were always expressed in the whole research phrase,such as Est-2,Est-4,AAT-3.As the global embryo formed,Est-1 and Est-3 disappeared,however,Pgi-3 only presented at the zygote stage.This isozyme variety implies that the zygote formed dependant on the expression of the sequence gene.
