Аннотация: An attempt has been undertaken to evaluate interrelations of gymnospermous and dicotyledonous plants on the basis of immunochemical studies of seed proteins. For this purpose, 12 antisera were raised to proteins of taxa representing four gymnosperm classes: Ginkgoopsida, Cycadopsida, Coniferopsida, and Gnetopsida. Seed proteins of eight dicotyledonous subclasses (after Takhtadzhyan, 1987) were used. The representatives of all dicotyledonous subclasses gave immunochemical reactions with those of all gymnospermous classes. The data obtained suggest the presence of sufficiently close immunochemical relations between gymnosperms and dicotyledons. Samples were found among the representatives of subclasses Dilleniidae, Hamamelididae, and Rosidae, which gave satisfactory reactions with eight to ten antisera to proteins of dicotyledonous seeds. Analysis of the data we obtained suggests that gymnospermous and dicotyledonous plants took their origin from a common pragymnospermous ancestor and later evolved independently or that dicotyledons separated from gymnosperms at an early stage of their evolution before divergence of the latter into several phyletic lineages.
