Ribosomal RNA from several blue-green algae was hybridized to DNA from Euglena gracilis chloroplasts by the membrane filter procedure. This hydridization was competitive with chloroplast ribosomal RNA and indicates significant genetic homology between blue-green algae and plastids from Euglena gracilis.
