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

Compatibility of azoxystrobin and cyproconazole on plant growth-promoting microorganisms
Weslany Silva Rocha,Mara Caroline Alves da Silva,Gilberto Coutinho Machado Filho,Mauro Gomes dos Santos,Aloisio Freitas Chagas Junior,Manoel Mota dos Santos +5 more
TL;DR: Azoxystrobin + cyproconazole at all tested doses is compatible with B. subtilis and S. japonicum and seoulensis, which were sensitive to all its doses until 288 hours after inoculation.

Significance of Microbial Agents in Augmentation of Plant Health
TL;DR: In this article, the authors evaluated entrapment into natural polymers such as alginate and their introduction to soil has been evaluated, and the results have revealed that they protect entrapped organisms from native soil microflora and further enable them to interact synergistically, thus allowing them to finally develop to a stable microbial community in rhizosphere.

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.
