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 document the presence of eight novel NifH types, which appear to
be a variety of significant components of the diazotrophic community,
dominated mainly by proteobacteria.
