title: Fast-Growing Rhizobium japonicum That Effectively Nodulates Several Commercial Glycine max L. Merrill Cultivars.
abstract: Several isolates of fast-growing Rhizobium japonicum that nodulate the wild soybean Glycine soja have been recently described (Keyser et al., Science 215:1631-1632, 1982). We demonstrate that one of these isolates, designated PRC 440 or USDA 191, has a wider host range than that previously reported and is able to nodulate several commercial Glycine max cultivars as effectively as does slow-growing R. japonicum 61A76. Electron microscopic examination revealed no obvious differences between strain 61A76- and strain USDA 191-induced nodules.
