Sequencing of RNA samples from batch culture bottle (CB) mercury methylation assays. Wild-type cultures of Pseudodesulfovibrio mercurii ND132 were grown with arsenic, methionine or adenosine to test for differential expression in transcriptome compared to control (no treatment). Three biological replicate samples (R1, R2, R3) for each treatments. This dataset includes the raw paired-end sequencing files in fastq format. For the adenosine treatment (Ad) the sample labeled 'BA' is the third biological replicate (equivalent to R3 for other treatments).
