Abstract

Previous research completed in this laboratory indicated the presence of homo serine lactones (HSL) in Bradyrhizobium japonicum. This research showed that only some strains make HSLs. PCR techniques were used to detect the presence of the HSL synthase gene in all B. japonicum strains to determine if HSL production correlated with the HSL synthase gene. It was found that strains that do not make HSLs, contain the HSL synthase gene. The strains that do make HSL, do not contain the HSL synthase gene. Our hypothesis is that the strains that contain the HSL synthase gene are making HSL that is not detectable using the current method.
