Abstract excerpt
Rhizobium fredii strain USDA257 produces nitrogen-fixing nodules on primitive soybean cultivars such as Peking but fails to nodulate agronomically improved cultivars such as McCall. Transposon-mutant 257DH4 has two new phenotypes: it nodulates McCall, and its ability to do so is sensitive to the...
