Nitrogen is abundant in the atmosphere but is generally the most limiting nutrient for plants.
The inability of many crop plants, such as cereals, to directly utilize freely available …

The availability of fixed nitrogen is a limiting factor in the net primary production of all
ecosystems. Diazotrophs overcome this limit through the conversion of atmospheric …

Nitrogen requirements for modern agriculture far exceed the levels of bioavailable nitrogen
in most arable soils. As a result, the addition of nitrogen fertilizer is necessary to sustain …

The ubiquitous diazotrophic soil bacterium Azotobacter vinelandii has been extensively
studied as a model organism for biological nitrogen fixation (BNF). In A. vinelandii, BNF is …

Plant-associated diazotrophs strongly relate to plant nitrogen (N) supply and growth.
However, our knowledge of diazotrophic community assembly and microbial N metabolism …

Non-symbiotic N2-fixation would greatly increase the versatility of N-biofertilizers for
sustainable agriculture. Genetic modification of diazotrophic bacteria has successfully …

Plant growth-promoting (PGP) bacteria are important to the development of sustainable
agricultural systems. PGP microbes that fix atmospheric nitrogen (diazotrophs) could …

Abstract Aim Rhizobium sp. IRBG74 (IRBG74), is a symbiont of Sesbania cannabina and a
growth promoting endophyte of rice. Here, we compare the transcriptomic and physiological …

The plant growth-promoting bacterium Gluconacetobacter diazotrophicus was originally
discovered in association with sugarcane plants as an endophyte. As a member of the small …

Uncontrolled usage of chemical fertilizers, climate change due to global warming, and the
ever-increasing demand for food have necessitated sustainable agricultural practices …
