RcsR1 (rhizobial cold and salinity stress riboregulator 1) trans-acting sRNA, formerly known as SmelC587, is a stress-related riboregulator, conserved in ''Sinorhizobium'', ''
Rhizobium'' and ''
Agrobacterium
''Agrobacterium'' is a genus of Gram-negative bacteria established by H. J. Conn that uses horizontal gene transfer to cause tumors in plants. ''Agrobacterium tumefaciens'' is the most commonly studied species in this genus. ''Agrobacterium'' is ...

highly conserved
In evolutionary biology, conserved sequences are identical or similar sequences in nucleic acids ( DNA and RNA) or proteins across species ( orthologous sequences), or within a genome ( paralogous sequences), or between donor and receptor taxa ( ...
stem-loops involved in the interaction with several target mRNAs (PhoR, MotE, anti-σE1, GntR, FgA, TrpC). In ''
Sinorhizobium meliloti'' RcsR1 less conserved central region is responsible for the species-specific interaction with the 5’UTR of
autoinducer synthase encoding mRNA ''sinI''. The interaction negatively influences ''sinI'' translation.
