dc.description.abstract | The rRNA genes are arranged in three sequential operons preceded by a fourth partial operon. Part or all of a 1462 nucleotide sequence extending from within the 3′-end of the 23S rRNA gene, across the 5S rRNA gene and a presumptive transcription terminator, to within the first structural gene (for 16S rRNA) of the rrn operon was determined for each region between operons. Homologies of the 3′-end of the 23S rRNA gene with the 4.5S rRNA genes of higher plant chloroplasts, and of the 5S rRNA gene with other 5S rRNA genes were examined. The region preceding the 16S rRNA gene, which is expected to contain sites for initiation and regulation of rrn transcription, includes a 305 base-pair sequence with substantial homology with structural genes elsewhere in the chloroplast genome. The homologies suggest that this portion of the leader evolved from copies of parts of the structural genes which had been inserted before the 16S rRNA genes. Thus the chloroplast rrn leader may provide a unique opportunity to study how a regulatory sequence evolved from well-defined structural genes. | en_US |
