Latest Patents
Eric Johansen holds a patent titled "Method for selecting mutants of legume-nodulating bacteria enhanced in - Methods for the isolation of mutant rhizobial strains with improved competition of nodulation (Comp.sup.+)." This patent presents a method for selecting mutants that exhibit constitutive expression of inducible nod genes in the absence of an inducer. The process involves screening for hyperinduction of nod genes when an inducer is present. Mutants that are defective in nodulation or symbiotic nitrogen fixation are eliminated from further testing. The methods described are particularly useful for isolating and identifying Comp.sup.+ mutants of Bradyrhizobium japonicum.
