Nitrogen-fixing bacteria associated with leguminous and non-leguminous plants
TLDR
A wide diversity of nitrogen-fixing bacterial species belonging to most phyla of the Bacteria domain have the capacity to colonize the rhizosphere and to interact with plants.Abstract:
Nitrogen is generally considered one of the major limiting nutrients in plant growth. The biological process responsible for reduction of molecular nitrogen into ammonia is referred to as nitrogen fixation. A wide diversity of nitrogen-fixing bacterial species belonging to most phyla of the Bacteria domain have the capacity to colonize the rhizosphere and to interact with plants. Leguminous and actinorhizal plants can obtain their nitrogen by association with rhizobia or Frankia via differentiation on their respective host plants of a specialized organ, the root nodule. Other symbiotic associations involve heterocystous cyanobacteria, while increasing numbers of nitrogen-fixing species have been identified as colonizing the root surface and, in some cases, the root interior of a variety of cereal crops and pasture grasses. Basic and advanced aspects of these associations are covered in this review.read more

TL;DR: The inoculation of nitrogen-fixing bacteria native to the northeast region in micropropagated seedlings of sugarcane variety RB867515 grown in pots promoted plant development and presented similar performance to the nitrogen treatment at 150 DAI.

Adaptive and progressive evolution of plant-microbial symbiosis
TL;DR: Analysis of the subscellular compartments of nodules in N2-fixing symbionts of legumes allows us to study the correlation of the mechanisms of the adaptive and progressive evolution of symbiosis, which is still unclear for free-living organisms.

Effect of single or dual inoculation of the arbuscular mycorrhizal fungus Glomus mosseae and root-nodulating rhizobacteria on reproduction of the burrowing nematode Radopholus similis on non-leguminous and leguminous banana intercrops

TL;DR: The bio-protective effect of either single or dual mycorrhizal (AMF) and rhizobial colonisation of the roots of non-leguminous and leguminous banana intercrops differing in host response to Radopholus similis on the reproduction of this important migratory endoparasitic nematode was examined.

Temporal Variations in Diazotrophic Communities and nifH Transcripts Level Across the Agricultural and Fallow Land at Jaipur, Rajasthan, India
Sushma Sharma,Dileep K. Singh +1 more
TL;DR: It is found that the agricultural land harbored unique nitrogen fixing communities that revealed different temporal patterns and abundance, and unique environmental factors and agricultural practices were responsible for the temporal shifts in bacterial community structures and nifH transcripts level.

Generic assignments, strain histories, and properties of pure cultures of cyanobacteria
TL;DR: Revisions are designed to permit the generic identification of cultures, often difficult through use of the field-based system of phycological classification, and are both constant and readily determinable in cultured material.

Applications of the acetylene-ethylene assay for measurement of nitrogen fixation
TL;DR: The biochemical basis of the assay is described along with relevant characteristics including Km, C2H2/N2 conversion factor, and specific N2[C2H 2]-fixing activities obtained with various systems, and methods of measurement of N2 fixation are compared.

Coordinating nodule morphogenesis with rhizobial infection in legumes.
TL;DR: This review focuses on the tissue-specific nature of the developmental processes associated with nodulation and the mechanisms by which these processes are coordinated during the formation of a nodule.

Genetic regulation of biological nitrogen fixation

TL;DR: The ability of microorganisms to use nitrogen gas as the sole nitrogen source and engage in symbioses with host plants confers many ecological advantages, but also incurs physiological penalties because the process is oxygen sensitive and energy dependent.
