For the rhizosphere soil sampling, the rhizome of G. elata was removed from the soil, shaken off the topsoil, and gently scraped the soil close to the rhizome using cotton swabs (at least 5 g). All soil samples were put in pre-labeled sterile bags and then conveyed to the laboratory at low temperatures. Next, they were sieved through a 2-mm mesh to discard residues. We randomly chose three samples (from the five) of each group for all analyses.
