Legumes form symbiotic relationship with root-nodule, rhizobia. The nitrogen (N 2) fixed by
legumes is a renewable source and of great importance to agriculture. Symbiotic nitrogen …

Rhizobia–legume symbiosis is an important type of plant–microbe mutualism; however, the
establishment of this association is complicated and can be affected by many factors. The …

Summary Soybean [Glycine max [L.] Merr.] is the most important legume cropped worldwide,
with important roles in human and animal nutrition, besides broad industrial applications …

Glycine max (soybean) plants can be nodulated by fast-growing rhizobial strains of the
genus Sinorhizobium as well as by slow-growing strains clustered in the genus …

Nitrogen (N2) fixation is one of the most important biological processes on earth, with a
commonly accepted estimate for global N2 fixation of 175 million metric tons (Tg) annually …

Progressive chemical and physical degradation of soil is a major factor affecting crop yield
worldwide (Cassman, 1999). The situation is most serious in tropical regions, where soils …

Microbial nitrogen transformation processes such as denitrification represent major sources
of the potent greenhouse gas nitrous oxide (N2O). Soil biochar amendment has been shown …

Growth and survival of Rhizobium leguminosarum bv. phaseoli, R. tropici, Bradyrhizobium
japonicum and Bacillus megaterium in peat and perlite-based inoculants were evaluated. In …

The family Rhizobiaceae is comprised of six genera of plant-associating bacteria,
Rhizobium, Bradyrhizobium, Sinorhizobium, Azorhizobium, Agrobacterium, and …

We mutagenized Sinorhizobium fredii HH103-1 with Tn 5-B20 and screened about 2,000
colonies for increased β-galactosidase activity in the presence of the flavonoid naringenin …
