title: The central part of the cyanelle rDNA unit of Cyanophora paradoxa: Sequence comparison with chloroplasts and cyanobacteria.
abstract: The 287-bp spacer and the flanking 3'-end of the 16S- and 5'-end of the 23S-rRNA genes of the cyanelles from Cyanophora paradoxa have been sequenced and compared with the corresponding regions of cyanobacteria and chloroplasts. The spacer contains the uninterrupted genes for tRNA(ile) and tRNA(ala). All coding regions show high homology to their prokaryotic counterparts. At the 3'-end of the 16S-rDNA a CCTCCTTT sequence has been identified which is complementary to putative ribosome binding sites observed immediately upstream of the coding region of cyanelle protein genes.
