ITS Amplicon Seq of TDUOF4
Microbial community DNA was extracted from soil samples using the Quick-DNA Fecal/Soil Microbe Miniprep Kit  according to manufactureres' instructions (Zymo Research, Freiburg, Germany). 16s Amplicons of BrdU-marked "active" DNA samples (Immunocapture technique) and total DNA samples were generated with the primer set BAC341f (5-CCTACGGGNGGCWGCAG-3) and BAC758R (3-GACTACHVGGGTATCTAAKCC-5) as suggested by Klindworth et al. (2013).
