Dissecting the effect of continuous cropping of potato on soil bacterial communities as revealed by high-throughput sequencing
Fig 1
A Venn diagram of the OTUs for bacterial communities in each soil sample.
Shared and unique OTUs in each sample were estimated at 97% similarity. The numbers of OTUs are indicated inside the diagrams. R-F: rotation soil; S-F-5: soil of potato continuous cropping for 5 years; S-F-10: soil of potato continuous cropping for 10 years; S-F-30: soil of potato continuous cropping for 30 years.
