Abstract

Some strains of Rhizobium japonicum are known to produce a chlorosis-inducing toxin called rhizobitoxine, an amino acid which reacts with ninhydrin to form a yellow product (Owens et al., 1972). A chlorosis-inducing toxin has also been found in the supernatant of broth cultures of some West African “cowpea” rhizobia (Eaglesham, Hassouna, 1982). Rhizobitoxine-producing strains of R. japonicum have been shown to possess a limited ability to nodulate non-nodulating (rj1) soybean (Devine, Weber, 1977). This report summarizes results of a search for strains of rhizobia capable of producing chlorosis-inducing toxins and a comparison of nodulating ability on rj1 soybean.
