Rhizobiales-2 RNA Motif
The Rhizobiales-2 RNA motif is a set of RNAs found in certain bacteria that are presumed to be homologous because they conserve a common primary and secondary structure (see diagram). The motif was discovered using bioinformatics, and is found only within bacteria that belong to the order Hyphomicrobiales (formerly Rhizobiales), in turn a kind of alphaproteobacteria. Because Rhizobiales-2 RNAs are not consistently located in proximity to genes of a consistent class or function, these RNAs are presumed to function as non-coding RNAs. See also *Flg-Rhizobiales RNA motif The ''flg''-Rhizobiales RNA motif is an RNA structure that is conserved in certain bacteria. All known ''flg''-Rhizobiales RNAs are located in the presumptive 5' untranslated regions of operons that contain genes whose functions relate to the c ...

Hyphomicrobiales
The ''Hyphomicrobiales'' are an order of Gram-negative Alphaproteobacteria. The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families. The four families ''Nitrobacteraceae'', ''Hyphomicrobiaceae'', '' Phyllobacteriaceae'', and ''Rhizobiaceae'' contain at least several genera of nitrogen-fixing, legume-nodulating, microsymbiotic bacteria. Examples are the genera ''Bradyrhizobium'' and ''Rhizobium''. Species of the ''Methylocystaceae'' are methanotrophs; they use methanol (CH3OH) or methane (CH4) as their sole energy and carbon sources. Other important genera are the human pathogens ''Bartonella'' and ''Brucella'', as well as ''Agrobacterium'' (useful in genetic engineering).
