Characterization and expression patterns of Sinorhizobium meliloti tmRNA (ssrA).

Résumé

tmRNA (ssrA) in Sinorhizobium meliloti is a small RNA annotated by homology with the Bradyrhizobium japonicum sra molecule. Here, this molecule is described in Sinorhizobium meliloti as a model for such molecules in Alphaproteobacteria subgroup-2. Northern blot analysis and mapping of both 5' and 3' ends of this tmRNA allow the identification of two pieces: a 214 nt mRNA-like domain and an 82 nt tRNA-like domain, both highly stable, whereas the premature form is unstable. Transcriptional studies reveal that Sinorhizobium meliloti tmRNA is mainly expressed during growth resumption, replication initiation and various stress responses.
