β¦ Synopsis
We have determined the nucleotide sequence of an unlinked 5 S rRNA gene region from a thermophilic archaebacterium, Thermococcus celer. This 5 S rRNA gene is flanked by a single tRNA(Asp) sequence and appears to be transcribed as part of a very short operon consisting of only two gene sequences. Comparative studies indicate features in the 5' and 3' flanking sequences, which bear similarity with promoter and termination signals in eubacteria, but also reflect unusual features found in at least some archaebacteria. The evolution of this unlinked operon and the unusual features are discussed.

The mitochondrial 18S and 5S ribosomal RNA (rRNA) genes of rye, plus a total of about 90 kilobase pairs of flanking DNA, have been cloned and maps of restriction enzyme cleavage sites have been constructed. Like their homologs from hexaploid wheat, the rye genes are closely linked and are part of a
