Relative abundance of the underestimated rhizosphere bacterial OTUs. These plant-associated OTUs were significantly enriched by plant in sand but turned to be general taxa with comparable abundance among groups in soil. The “*” means significantly enriched biomarkers by plant in sand compared to the unplanted control, as indicated by the STAMP software (corrected P value < 0.05, calculated using the Bonferroni correction). The error bars show calculated standard error of triplicate samples. PN, bahiagrass; SG, stylo; CK, the unplanted control.
