Ambiguous controls on simulated diazotrophs in the world oceans [PDF]
Scientific Reports, 2022 Nitrogen fixers, or diazotrophs, play a key role in the nitrogen and carbon cycle of the world oceans. Diazotrophs are capable of utilising atmospheric dinitrogen which is a competitive advantage over generally faster growing ordinary phytoplankton in ...

Free-living diazotrophs drive castor bean nitrogen input in tropical semiarid soils [PDF]
Ciência Rural, 2019 : There are few studies of microbial diversity in castor bean soils in tropical semiarid environmental. Castor bean products have been widely used around the world justifying the commercial importance of ricinoculture in Brazil’ northeastern semiarid ...

Nitrogen Fixation and Diazotrophs – A Review
Romanian Biotechnological Letters, 2021 Nitrogen fixation involves formation of ammonium from N2, which needs a high input of energy. Biological nitrogen fixation utilizes the enzyme nitrogenase and ATP to fix nitrogen. Nitrogenase contains a Fe-protein and a Mo-Fe-protein and other metal cofactors.

Bleaching forces coral’s heterotrophy on diazotrophs and Synechococcus [PDF]
The ISME Journal, 2019 Abstract Coral reefs are threatened by global warming, which disrupts the symbiosis between corals and their photosynthetic symbionts (Symbiodiniaceae), leading to mass coral bleaching. Planktonic diazotrophs or dinitrogen (N2)-fixing prokaryotes are abundant in coral lagoon waters and could be an alternative nutrient source for corals ...

Redox Regulation in Diazotrophic Bacteria in Interaction with Plants [PDF]
Antioxidants, 2021 Plants interact with a large number of microorganisms that greatly influence their growth and health. Among the beneficial microorganisms, rhizosphere bacteria known as Plant Growth Promoting Bacteria increase plant fitness by producing compounds such as

Genetic and physiological insights into the diazotrophic activity of a non-cyanobacterial marine diazotroph [PDF]
Environmental Microbiology, 2022 Abstract Nitrogen (N 2 ) fixation, or diazotrophy, supports a large part of primary production in oceans. Culture-independent approaches highlighted the presence in abundance of marine non-cyanobacterial diazotrophs (NCD) but their ecophysiology remains elusive, mostly because of ...

Draft Genome Sequences of Switchgrass Diazotrophs
Microbiology Resource Announcements, 2021 We report the draft genome sequences of five native nitrogen-fixing bacteria associated with roots of switchgrass isolated from the Tallgrass Prairies of Oklahoma. Nitrogen-fixing genes, including the nif cluster, are conserved across the Klebsiella and Kosakonia ...

Effects of Selected Diazotrophs on Maize Growth [PDF]
Frontiers in Plant Science, 2016 Laboratory, greenhouse, and field experiments were conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa in the 2010/2011 and 2011∖2012 seasons to study the effects of eight strains of diazotrophic bacteria on the growth and yield of maize. Maize seeds were treated with Bacillus megaterium (V16), Pseudomonas sp.

Agronomy, 2023 Soybeans can simultaneously form tripartite symbiotic associations with arbuscular mycorrhizal fungi (AMF) and diazotrophs. However, no studies have explored whether soybean genotypes differing in their maturity groups (MGs) may have implications for the
