Studying within-species variation has traditionally been limited to culturable bacterial
isolates and low-resolution microbial community fingerprinting. Metagenomic sequencing …

Biological nitrogen fixation by Rhizobium-legume symbioses represents an environmentally
friendly and inexpensive alternative to the use of chemical nitrogen fertilizers in legume …

Metagenomics (also referred to as environmental and community genomics) is the genomic
analysis of microorganisms by direct extraction and cloning of DNA from an assemblage of …

Bacterial accessory genes are genomic symbionts with an evolutionary history and future
that is different from that of their hosts. Packages of accessory genes move from strain to …

Plant roots support the growth and activities of a wide variety of microorganisms that may
have a profound effect on the growth and/or health of plants. Among these microorganisms …

Colonization of the rhizosphere by micro‐organisms results in modifications in plant growth
and development. This review examines the mechanisms involved in growth promotion by …

Biological nitrogen (N2) fixation is an important aspect of sustainable and environmentally
friendly food production and long-term crop productivity. The amount of N2 fixed is primarily …

The appeal of using microbial inoculants to mediate plant traits and productivity in managed
ecosystems has increased over the past decade, because microbes represent an alternative …

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 …

Rhizobia were isolated from nodules off a stand of Lotus corniculatus established with a
