αr7 is a family of bacterial small non-coding RNAs with representatives in a broad group of Alphaproteobacterial species from the order Hyphomicrobiales. The first member of this family (Smr7C 150nt) was found in a Sinorhizobium meliloti 1021 locus located in the chromosome (C). Further homology and structure conservation analysis identified full-length homologs in several nitrogen-fixing symbiotic rhizobia (i.e. R. leguminosarum bv.viciae, R. leguminosarum bv. trifolii, R. etli, and several Mesorhizobium species), in the plant pathogens belonging to Agrobacterium species (i.e. A. tumefaciens, A. vitis, A. radiobacter, and Agrobacterium H13) as well as in a broad spectrum of Brucella species (B. ovis, B. canis, B. abortus and B. microtis, and several biobars of B. melitensis). αr7 RNA spec

- Consensus secondary structure of Smr7C and the ar7 family predicted by RNA and RNAalifold. The color scheme of Smr7C represents the base pairs probabilities. The coloring scheme for the ar7 family structure is based on the base pairs conservation: Red: base pair occurring in all sequences used to generate the consensus; yellow: two types of base pairing occur; Green: three types of base pairing occur. The shading of base pairs represents: Saturated, no inconsistent sequences; Pale, one inconsistent sequence; Very pale, two inconsistent sequences. (en)
