| Outline of Final Research Achievements |
Our analysis using genome sequence databases of Escherichia coli and the budding yeast indicated that long-chain inverted repeats are present at several sites. Mutants bearing deletions for these genomic sites were constructed and phenotypes of the resultant mutants were analyzed in detail. As a result, in Escherichia coli, a single site was suggested to have an important function in cell growth under certain conditions. This site was located in an intergenic region, and was indicated to be transcribed, yielding non-coding RNA. In addition, this non-coding RNA was suggested to be synthesized by transcriptional readthrough from a gene located upstream of the site.
