Distance–decay relationships between the bacterial (a) and fungal (b) community similarity (Bray–Curtis distances) and the geographical distances in rhizosphere soil and root endosphere habitats across the 58 sampling sites. The shaded region represents the 95% confidence limits of the regression estimates. The solid and dashed lines denote statistically significant (P < 0.05) and nonsignificant relationships, respectively. Soil, rhizosphere soil; Root, root endosphere
