Dot-blot analysis of luxRI gene homologs from Aeromonas strains. A representative dot-blot showing the presence of luxRI homologs in all the strains that showed no PCR amplification for either luxR or luxI homolog. The negative control (genomic DNA of Selenomonas lipolytica) and positive control (genomic DNA of A. culicicola) are also shown.
