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

History of soil fertility enhancement with inoculation methods A termékenységet javító baktériumos talajoltás történeti áttekintése
TL;DR: The soil-plant-microbe systems are so multifactorial arrangements, than there are several biotic and abiotic factors influencing of their real functioning, and more should be learned how those systems are really working.

Isolation and Characterization of Plant Growth Promoting Bacteria Isolated from Andean Soil as Potential Inoculants of Soybean Seeds
TL;DR: The results encourage deeper studies to achieve the formulation of inoculums to use as a biofertilizer, which would replace chemical fertilizers or reduce their doses.

Co-composting of fresh tobacco leaves and soil: an exploration on the utilization of fresh tobacco waste in farmland
TL;DR: In this paper, a co-composting of fresh tobacco waste and soil in farmland was investigated, and the obtained compost product was applied into the soil instead of a part of tobacco-specific fertilizer.

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.

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.
