Microbial structural and expression profiles of the rhizospheres of three legumes, faba beans, peas and white lupin, were compared by RNA-arbitrarily primed PCR technique. Two different primers, M13 reverse and 10-mer primers, were used in the amplification and products resolved on non-denaturing polyacrylamide gel. With both DNA and RNA profiles Lupinus and Pisum rhizospheres were more similar to each other than to Vicia rhizosphere. The RAP-PCR products were also dot blotted and probed for bacterial peptidase transcripts. Plant-dependent rhizosphere effect was evident by the marked absence of transcripts for bacterial neutral metallopeptidase in Lupinus rhizosphere. The results of dot blot were further confirmed by RT-PCR for the expression of bacterial neutral metallopeptidase in the three rhizospheres. © 2004 Federation of European Microbiological Societies.
