Transmissible Resistance to Penicillin G, Neomycin, and Chloramphenicol in Rhizobium japonicum1
The genetic basis for resistance to a number of antibiotics was examined in Rhizobium japonicum. Resistance to penicillin G, neomycin, and chloramphenicol appears to be mediated by an… Expand
DNA : DNA hybridization studies of Rhizobium japonicum and related Rhizobiaceae
The symbiotic nitrogen-fixing bacteria associated with soybeans (Glycine max) have been classified routinely as Rhizobium japonicum. DNA:DNA hybridization studies were conducted to estimate the… Expand
Genetic diversity among bradyrhizobium isolates that effectively nodulate peanut (Arachis hypogaea).
Symbiotic gene diversity and other measures of genetic diversity were examined in Bradyrhizobium isolates that form an effective symbiosis with peanut (Arachis hypogaea). Initially, restriction… Expand
Variation for Nitrogen Fixation Among Progenies of a Virginia ✕ Spanish Peanut Cross 1
One method of increasing symbiotic N₂ fixation is to improve the N₂-fixing potential of the host plant. Peanut (Arachis hypogaea L.) cultivars of the Virginia (ssp. hypogaea var. hypogaea) and… Expand
Taxonomy of the rhizobia
- G. Elkan
- 1 June 1992
Extensive cross testing on a relatively few legume hosts led initially to a taxonomic characterization of rhizobia based on bacteria–plant cross–inoculation groups. This has gradually become less… Expand
Glucose catabolism in Rhizobium japonicum.
Glucose catabolism in Rhizobium japonicum ATCC 10324 was investigated by the radiorespirometric method and by assaying for key enzymes of the major energy-yielding pathways. Specifically labeled… Expand
Rhizobium fredii sp. nov., a fast-growing species that effectively nodulates soybeans
A new species, Rhizobium fredii, is proposed for fast-growing root nodule bacteria isolated from soybeans. The type strain was isolated from a root nodule of Glycine max growing in Honan Province,… Expand
Multiple antibiotic resistance in Rhizobium japonicum.
A total of 48 strains of the soil bacterium Rhizobium japonicum were screened for their response to several widely used antibiotics. Over 60% of the strains were resistant to chloramphenicol,… Expand
