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

Community structure and functional diversity of the plastisphere in aquaculture waters: Does plastic color matter?
TL;DR: The results showed that plastisphere communities exhibited a higher diversity and evenness compared with the water community, which might indicate a plastic color/additive-driven selection of microorganisms on MPs.

Global database of plants with root‐symbiotic nitrogen fixation: NodDB
TL;DR: Nitrogenfixing mutualistic relationships between plant roots and bacteria have evolved multiple times in both partners and are widely distributed across all terrestrial biomes and continents apart from Antarctica.

Soil Rhizobacteria Regulating the Uptake of Nutrients and Undesirable Elements by Plants
TL;DR: Different mechanisms are discussed by which, depending on the specific conditions, plants benefit from growth and development of rhizobacterial population, and different combinations of mechanisms presented in soils are reviewed.

Beatriz Ruiz-Díez,Miguel Angel Quiñones,Susana Fajardo,Miguel Ángel López,Pablo Higueras,Mercedes Fernández-Pascual +5 more
TL;DR: Three isolates were selected for bioremediation processes with restoration purposes on the basis of their levels of Hg tolerance, their response to high concentrations of this heavy metal, and their genetic affiliation and nodulation capacity.

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.

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.
