Studies of microbial diversity after inoculation strain B6
The rhizosphere soil and roots samples for microbial measurements were taken on the 28th day after inoculation strain B6, when microbial populations were at their peak. PCR amplicon libraries for bacterial 16 S rDNA genes was assembled with primer pairs 799F /1193R by an ABI GeneAmp 9700 PCR thermocycler (ABI, CA, USA).
