, 2013), modified to include the addition of forward primer dsrB F1i (Table S1), which was generated using AZD6244 information from the successful DNA sequencing of full-length dsrAB. Two successive hot-start PCRs were performed as described above, with the exception that primers DSRB F1mix (equimolar mixture of 10 ��M each DSRB F variant) and DSRB 4RSImix (equimolar mixture of 10 ��M each DSRB 4RSI variant) (Table S1) were used in the second PCR reaction. Negative control PCR reactions yielded no visible product on an agarose gel. Amplified fragments of anticipated length were excised from a 1% agarose gel and subsequently purified using the QIAquick gel extraction kit (Qiagen). Replicate dsrAB and dsrB PCR products were pooled together and cloned using the BigEasy v2.0 Long PCR Cloning Kit (Lucigen, Middleton, WI, USA). Clones were sequenced bidirectionally (dsrAB) or unidirectionally (dsrB) on an ABI 3730XL DNA Analyzer (Applied Biosystems, Carlsbad, CA, USA). Internal sequencing of dsrAB was performed using previously developed internal primers dsr619F (5��-GYCCGGCVTTCCCSTACAA-3��) and dsr1905BR (5��-ATGTGCGGCGCSGTDCAY-3��) Telomerase (Giloteaux et al., 2010). dsrAB and dsrB gene analysis DNA sequences were trimmed of vector sequence and manually curated using Sequencher version 5.1 software (GeneCodes, Ann Arbor, MI, USA). Full length dsrAB sequences were assembled using Sequencher default parameters. Clone sequences were aligned using the ARB software package (Ludwig et al., 2004) ��integrated aligners�� tool with a previously published database of aligned dsrAB sequences (Loy et al., 2009). Additional sequences that were most similar to clone sequences obtained in this study, as revealed by BLAST search against the non-redundant nucleotide database (Altschul et al., 1990), were aligned as described above and included in relevant phylogenetic analyses. A statistical selection of best-fit models of nucleotide substitution was performed on the DNA sequence alignment using jModelTest (Darriba et al., 2012) version 2.1.1. Phylogenetic analyses were performed with the RAxML maximum likelihood method using the GTR model MDV3100 in vitro of nucleotide substitution under the gamma- and invariable-models of rate heterogeneity (Stamatakis, 2006). Trees with the highest log likelihood score were selected from performing 100 iterations of the RAxML method. Phylogenies for the guide tree (Figure 5) and Archaea tree (Figure S1) were constructed initially using near full-length dsrB; sequence fragments of short length (
