Biased 16S rDNA PCR amplification caused by interference from DNA flanking the template region

Abstract: PCR amplification of 16S rDNA was found to be highly biased, so that the rDNA from one species out of four was preferentially amplified. We present evidence that the observed PCR bias most likely occurs because the genomic DNA of some species contains segments outside the amplified sequence that inhibit the initial PCR steps. Attempts to overcome this bias by use of a ‘touch down’ PCR procedure or by performing PCR in the presence of denaturants or cosolvents such as acetamide, DMSO, or glycerol were unsuccess… Show more

“…PCR amplification of the V3 region of the 16S rRNA gene The total DNA in replicate samples was pooled together for PCR using the forward primer U341F (5 0 -CCTACGGGRSGCAGCAG-3 0 ) (Hansen et al, 1998) and reverse primer R685 (5 0 -ATCTACGC ATTTCACCGCTAC-3 0 ) for bacteria (Wang et al, 2004), and the forward primer A344F (5 0 -AYGGGGY GCASCAGGSG-3 0 ) and reverse primer A519R (5 0 -GG TDTTACCGCGGCKGCTG-3 0 ) for archaea (Teske and Sorensen, 2007) in separate reactions. A set of sixnucleotide (nt) barcodes was designed and added to the 5 0 end of U341F, R685, A344F and A519R for the multiplexing of samples in the pyrosequencing runs.…”

“…with the Qiagen kit suggests that the bias was not introduced at the DNAextraction phase. Differences in secondary structure affecting either the availability of the priming sites or the polymerization reaction may cause amplification bias [11]. In any case, our results emphasize that either multiple primer pairs or both molecular and culture-based approaches should be used when characterizing microbial communities [11,26].…”

“…Bias in phylogenetic analysis is introduced through differential amplification caused by differences in the efficiency of primer binding, interference by sequences flanking primer regions (Hansen et al, 1998) and differences in the kinetics of the PCR reaction. (e.g., Brunk and Eis, 1998;Reysenbach and Pace, 1995;Suzuki and Giovanni, 1996).…”
