FIG 1.
Soil bacterial β-diversity/community composition in the field soil between rows and the soil near sorghum roots at three time points during the field season in 2016. Four weeks corresponds to the seventh-leaf stage, 9 weeks to boot stage, and 13 weeks to grain fill stage. All the soil samples separated by time for NMDS ordination by using the Bray-Curtis matrix. The P values and R2 on the top left of each graph show the PERMANOVA results. The stress values at the bottom right corners of the plots reflect how well the ordination summarizes the observed distances among the samples.
