Although no accurate information is available, it seems clear that world-wide production of
legume inoculant is static or in decline. This is a paradoxical situation in a world where …

Most of the legumes have the ability to establish a dinitrogen-fixing association with bacteria
defined as rhizobia. The legume crops will benefit from this symbiosis only when the plant …

Inputs of biologically fixed nitrogen derived from the symbiotic relationship between legumes
and their root-nodule bacteria into terrestrial ecosystems amount to at least 70 million metric …

Forty-eight strains representing the eight recognized Rhizobium species, two new
Phaseolus bean Rhizobium genomic species, Bradyrhizobium spp., Agrobacterium spp …

Characterization of 43 strains of Rhizobium leguminosarum biovars viciae, trifolii, and
phaseoli was performed by two methodologies based on PCR amplification, ie, PCR DNA …

This study was conducted in an area of Brazil cultivated with soybean since the early 1960's
but which for the last 17 yr was under different tillage (no-tillage, NT; conventional tillage …

Seventeen Bradyrhizobium sp. strains and one Azorhizobium strain were compared on the
basis of five genetic and phenetic features:(i) partial sequence analyses of the 16S rRNA …

Twenty-seven new Rhizobium isolates were obtained from root nodules of wild and crop
legumes belonging to the genera Vicia, Lathyrus and Pisum from different agroecological …

Abstract Primers (10-mers) of random sequence were used to amplify RAPD bands from
genomic DNA of an F1 strain of flax rust (Melampsora lini) and its two parent strains. One …

Total genomic DNA isolated from Rhizobium spp was analysed by the polymerase chain
reaction (PCR) in conjunction with either arbitrary oligonucleotide primers or a 20-base …
