Succinate-sensitive, nodulation-enhancing Rhizobium mutants for use with legumes

摘要

Nodulation-enhancing mutants of Rhizobium species are prepared by growing a wild-type strain in a medium as the only carbon source at a sub- minimum concentration for normal growth, the mutant cells thus obtained are further selected by comparative nodulation to obtain mutants which produce two to three times as many nodules as the corresponding wild-type strain.
