Phytoserologie Als Methode Der Vergleichenden Verwandtschaftsforschung–einst Und Jetzt

Abstract

Summary Phytoserology uses the specific properties of immunosera produced by animals against plant protein characters to assess plant relationships. Unlike animal serum proteins, plant protein extracts have peculiar properties which make phytoserological work difficult. Careful experiments by early workers gave phytoserology a hopeful start but this was spoiled by the inadequate methods of the Königsberg school and the extravagant claims for their evolutionary tree. Thanks to the critical new start made by Otto Moritz in the 1950s, phytoserology is now established as a valid method in systematics just as it is in immunology and protein chemistry.
