FIGURE 5 Impacts of abiotic and biotic factors on microbial
compositions in rhizosphere (Rs) and non-rhizosphere (Non-Rs) . Notes:
Mantel results on the impacts of examined variables on bacterial and
fungal compositions (a) . Relative roles of six variables with
low-collinearity on rhizosphere (b) and non-rhizosphere
bacterial compositions (c) . Relative roles of six variables
with low-collinearity on rhizosphere (d) and non-rhizosphere
fungal compositions (e) . SBI, RBI, RTC, RTN, STC, STN, STP,
SAN, SAP, and SM are the same as in Figure 4. OverallR 2 indicates the total explained fraction by
the six variables.
