Conversion from natural wetlands to paddy field alters the composition of soil bacterial communities in Sanjiang Plain, Northeast China

Table 5 UniFrac P-test values as calculated by 16S rRNA gene clone libraries at total clones and individual phylum level from a paddy field soil and two natural wetland soils in the Sanjiang Plain, NE China

Sample	Total clones		Proteobacteria		Actinobacteria		Firmicutes		Acidobacteria		Verrucomicobia		Chloroflexi

^aPad, C. la, and D. an represent soil samples of paddy field, wetland with plant of Carex lasiocarpa and Deyeuxia angustifolia, respectively
^bThe values were in <0.001, 0.001–0.01, 0.01–0.05, and >0.05 indicated that two samples were highly significant, significant, marginally significant, and not significant, respectively
^cOnly a clone belong to Chloroflexi was observed in paddy field, the UniFrac P-test was not performed between the paddy field and the two natural wetlands
