Aspects of the relation between Cyanophora paradoxa (Korschikoff) and its endosymbiotic cyanelles Cyanocyta korschikoffiana (Hall & Claus) - III. Characterization of ribosomal ribonucleic acids

Abstract

Analysis of ribosomal RNA from Cyanophora paradoxa (Korschikoff) demonstrated the existence of four species. Two species, 25 S and 18 S r-RNA, are characteristic of the host, while two other species, 23 S and 16 S , are characteristic of the endosymbiotic cyanelles, Cyanocyta korschikoffiana (Hall & Claus). The 23 S r-RNA from C. korschikoffiana was found to be labile and yielded degradation patterns resembling those seen in some chloroplast r-RNA preparations.
