amplicon-16S-C2-1
The primers F341 and R806 targeting 16S rRNA gene V3-V4 region were selected . All DNA samples were sent to Realbio Genomics Institute (Shanghai, China) for library construction and sequencing. Amplicon sequencing was performed on an Illumina Hiseq 2500 platform, for each sample about 100,000 250 bp paired-end (PE) reads were generated.
