Abstract

A survey of the phloem-protein (P-protein) in species of "primitive" angiosperms was undertaken to provide possible evidence for P-protein function from a phylogenetic point of view. The ontogeny and substructure of P-protein in Liriodendron tulipifera and Magnolia soulangeana are similar to that of more advanced dicot species. In the light of this information the time of P-protein evolution seems to coincide with the development of the angiosperms themselves.
