Fifty-five Chinese isolates from nodules of Amorpha fruticosa were characterized and
compared with the type strains of the species and genera of bacteria which form nitrogen …

▪ Abstract Gene amplification is a common feature of the genome of prokaryotic organisms.
In this review, we analyze different instances of gene amplification in a variety of …

The rhizobium–legume symbiosis is a major source of fixed nitrogen (ammonia) in the
biosphere. The potential for this process to increase agricultural yield while reducing the …

DNA repeats are causes and consequences of genome plasticity. Repeats are created by
intrachromosomal recombination or horizontal transfer. They are targeted by recombination …

The nitrogen-fixing rhizobial symbionts of Sesbania herbacea growing in the nature reserve
at the Sierra de Huautla, Mexico, were isolated and characterized. All 104 isolates together …

Background Symbiotic bacteria known as rhizobia interact with the roots of legumes and
induce the formation of nitrogen-fixing nodules. In rhizobia, essential genes for symbiosis …

We investigated the genetic diversity of 96 Rhizobium meliloti strains isolated from nodules
of four Medicago sativa varieties from distinct geographic areas and planted in two different …

Fifty rhizobial isolates from root nodules of Mimosa affinis, a small leguminous plant native to
Mexico, were identified as Rhizobium etli on the basis of the results of PCR-RFLP and RFLP …

Rhizobium leguminosarum bv. phaseoli CFN42 contains six plasmids (pa to pf), and pd has
been shown to be the symbiotic plasmid. To determine the participation of the other …

The stability of the genetic structure of rhizobial populations nodulating Phaseolus vulgaris
cultivated in a traditionally managed milpa plot in Mexico was studied over three …
