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

Legume Beverages from Chickpea and Lupin, as New Milk Alternatives
TL;DR: All pulses-based beverages are typical non-Newtonian fluids, similarly to current non-dairy alternative beverages, and sensory results show that chickpea beverage with cooking water has the best taste and the sprouted chickPEa beverage presents the most pronounced shear-thinning behavior of all formulations.

A global survey of the bacteria within earthworm nephridia
TL;DR: The study aimed to identify members of Crassiclitellata families that harbor bacteria in their nephridia, and identify these bacteria based on 16S rRNA gene sequences and suggest a contribution to nitrogen conservation for the earthworms.

Cobalt: An Essential Micronutrient for Plant Growth?
TL;DR: Cobalt is a transition metal located in the fourth row of the Periodic Table and is a neighbor of iron (Fe) and nickel (Ni), but its essentiality for plants remains obscure as mentioned in this paper.

Cultivar-Dependent Variation of the Cotton Rhizosphere and Endosphere Microbiome Under Field Conditions
Wei Feng,Zhao Lihong,Xiangming Xu,Feng Hongjie,Shi Yongqiang,Greg Deakin,Feng Zili,Zhu Heqin +7 more
TL;DR: It is suggested that specific rhizosphere and endosphere microbes may contribute to cotton resistance to V. dahliae, and greenhouse studies with sterilized soil supported that beneficial microbes in the Rhizosphere contribute to reduced wilt development.

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.
