text_B: αr35 is a family of bacterial small non-coding RNAs with representatives in a reduced group of α-proteobacteria from the order Rhizobiales .. Rhizobiales. Rhizobiales. The first member of this family -LRB- Smr35B -RRB- was found in a Sinorhizobium meliloti 1021 locus located in the symbiotic plasmid B -LRB- pSymB -RRB- .. Sinorhizobium meliloti. Sinorhizobium meliloti. Further homology and structure conservation analysis have identified full-length SmrB35 homologs in other legume symbionts -LRB- i.e. Rhizobium leguminosarum bv.viciae , R. leguminosarum bv .. Rhizobium leguminosarum. Rhizobium leguminosarum. trifolii and R. etli -RRB- , as well as in the human and plant pathogens Ochrobactrum anthropi and Agrobacterium tumefaciens , respectively .. Agrobacterium tumefaciens. Agrobacterium tumefaciens. αr35 RNA species are 139-142 nt long -LRB- Table 1 -RRB- and share a common secondary structure consisting of two stem loops and a well conserved rho independent terminator -LRB- Figure 1 , 2 , 3 -RRB- .. RNA. RNA. Most of the αr35 transcripts can be catalogued as trans-acting sRNAs expressed from well-defined promoter regions of independent transcription units within intergenic regions of the α-proteobacterial genomes -LRB- Figure 5 -RRB- .
