Figure 2: In silico evaluation of primer sets for the detection of archaeal metabolic genes. Archaeal (a) and bacterial (b) reference sequences containing the targeted metabolic gene were screened for binding sites for the gene-specific primers. Dark grey: sequences with binding sites for both primers; hatched: sequences with binding sites for one primer; light grey: sequences without binding site.
