denitrification

Denitrification activity and gene abundance in relation to land use and aggregate size.

Here is the Abstract from this paper:
Human activities have increased greenhouse gas concentrations in the atmosphere. Research has demonstrated this increased concentration will affect our climate

Gene transcription, nirK

Here is another Wallensten review, with location of denitrification genes in the cell.

Here is the updated (updated) list of primers for the 4 denitrification genes of interest. This list is very similar to Kurt's updated primer list and also works off of Ranae's primer list. The primer pairs highlighted in yellow are those that seem like the best first shot based on their use on soil samples, their reliability across studies, and if they have been used for SYBR green-based qPCR.
