Study on the response of soil DNA and RNA viruses and their hosts under warming in Qinling forest.

Here, we investigate the soil viral communities and the virus host interactions after 3 years warming based on soil translocation experiment (from 2200 to 1300 m asl) in Qinling forest soil. Eight soil cores were reinstalled in situ (hereafter referred to as Control) and the other eight were relocated to the low elevation (hereafter referred to as Warm), a warming process by soil translocation. Raw data from metagenome was used to generalize the characteristic of DNA viruses and functions of hosts. Raw data from metatranscriptome was used to generalize the characteristic of RNA viruses. We used the 16S rRNA gene to amplify the V3 V4 region sequences to generalize the abundance of bacterial hosts. The abundance of fungal hosts was detected using high-throughput sequencing of the internal transcribed spacer (ITS1) region. This study suggested that DNA and RNA viruses showed opposite response to soil warming and different changes of viral hosts.
