Materials and methods for the enhancement of effective root nodulation in legumes

摘要

The subject invention relates to compounds and compositions which induce transcription of the nolA gene in nitrogen-fixing bacteria, such as Bradyrhizobium japonicum. Novel bacterial strains which are insensitive to NolA, soil inoculants comprising NolA insensitive bacteria and/or nolA inducers, and methods of increasing nitrogen fixation in legumes are also disclosed.
