Abstract excerpt
To demonstrate the extent of phylogenetic diversity of diazotrophic bacteria associated with rice roots, we characterized phylogenetically 23 nifH gene sequences obtained by PCR amplification of mixed organism DNA extracted directly from rice roots without culturing the organisms. The analyses do...
