N2 - The rpl35, rpl20, rpl5, rps8, and a portion of the rpl6 genes of the cyanelle genome of Cyanophora paradoxa have been cloned, mapped and sequenced. Homologs of the rpl35, rpl5, and rpl6 genes are not found in the chloroplasts of higher plants. The rpl35 and rpl20 genes most likely form a dicistronic operon which is located upstream from the apcE-apcA-apcB locus of the cyanelle and which is divergently transcribed from this locus. The rpl5, rpl8, and rpl6 genes probably form a part of a larger cluster of genes encoding components of the cyanellar ribosomes. These genes are organized in a fashion similar to that observed in all procaryotes examined to date, with the exception that the rpsl4 gene is not found between the rpl5 and rps8 coding sequences. Hypotheses concerning the origins of cyanelles and chloroplasts are discussed.
