Ensifer (syn. Sinorhizobium) meliloti U143 is an effective nitrogen-fixing strain isolated from
Uruguayan soils. For decades, this strain has been used as an inoculant for different alfalfa …

The growth and persistence of alfalfa (Medicago sativa), a perennial legume capable of
producing high yields of high-quality forage, is reduced in moderately acidic soils. The low …

Alfalfa (Medicago sativa) is the most cultivated forage legume for cattle and animal feeding,
occupying about 32 million hectares over the world. Management of the N2-fixing symbiosis …

Here, we report an improved and complete genome sequence of Sinorhizobium (Ensifer)
meliloti strain WSM1022, a microsymbiont of Medicago species, revealing its tripartite …

Improving symbiotic nitrogen fixation would reduce reliance on synthetic fertilizers, but
establishment of effective bacterial strains is hampered due to competition by indigenous …

Background Sinorhizobium meliloti is a model system for the studies of symbiotic nitrogen
fixation. An extensive polymorphism at the genetic and phenotypic level is present in natural …

Abstract Sinorhizobium meliloti (Syn. Ensifer meliloti) is a model species for the study of
nitrogen fixation and genomic diversity. This species is distributed worldwide in many …

Background Nitrogen fixing bacteria isolated from hot arid areas in Asia, Africa and America
but from diverse leguminous plants have been recently identified as belonging to a possible …

The symbiotic, nitrogen-fixing bacterium Sinorhizobium meliloti has been widely studied due
to its ability to improve crop yields through direct interactions with leguminous plants. S …

Despite the vast screening for natural nitrogen-fixing isolates by public and private consortia,
no significant progresses in the production of improved nitrogen-fixing inoculants for alfalfa …
