Abstract
A pair of special conservative primers and a pair of complete gene primers were designed based on the released nol A gene(Genbank number: AF322013) of Bradyrhizobium japonicum in the study.PCR amplification results showed that Sinorhizobium fredii strain HH21 contained nol A gene,too.Nodulation repression was also proved in Sinorhizobium fredii strain HH21 by plant nodulation experiments conducted in pot and test tube.This character was triggered by the expression of nol A gene in Bradyrhizobium japonicum and controlled by the pathway of population density-dependent regulation.
