    Abstract: The subject invention relates to compounds and compositions which induce transcripts of the nolA gene in nitrogen-fixing bacteria, such as Bradyrhizobium japonicum. Novel bacterial strains which are insensitive too NolA, soil inoculants comprising NolA insensitive bacteria and/or nolA inducers, and methods of increasing nitrogen fixation in legumes are also disclosed.
    Type: Grant
    Filed: July 20, 2001
    Date of Patent: February 15, 2005

  • DNA encoding carbohydrate binding protein and biological materials derived therefrom
    Patent number: 5863728
    Abstract: A DNA fragment encoding a carbohydrate binding lectin BJ38 in chromosomal DNA of Bradyrhizobium japonicum is described. The DNA is used as a source of the lectin, as a probe and as DNA for recombinant strains of rhizobium with enhanced nodulation and production in legumes.
