Phosphorus Limitation Enhances Diazotroph Zinc Quotas

Frontiers in Microbiology, 2022
Trichodesmium spp. is a colonial diazotrophic cyanobacterium found in the oligotrophic (sub)tropical oceans, where dissolved inorganic phosphorus (DIP) can be depleted. To cope with low P concentrations, P can be scavenged from the dissolved organic P (DOP) pool.

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 ...

Arbuscular Mycorrhizal Fungi and Diazotrophic Diversity and Community Composition Responses to Soybean Genotypes from Different Maturity Groups

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

Contribution of Heterotrophic Diazotrophs to N2 Fixation in a Eutrophic River: Free-Living vs. Aggregate-Associated

Frontiers in Microbiology, 2022
Recent studies have indicated that heterotrophic diazotrophs are highly diverse and fix N2 in aquatic environments with potentially adverse conditions for diazotrophy, such as oxic and rich in total nitrogen.

Synergistic effects of diazotrophs and arbuscular mycorrhizal fungi on soil biological nitrogen fixation after three decades of fertilization

iMeta, 2023
Biological nitrogen (N) fixation (BNF) via diazotrophs is an important ecological process for the conversion of atmospheric N to biologically available N.

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.

Heterotrophic Nitrogen Fixation at the Hyper-Eutrophic Qishon River and Estuary System

Frontiers in Microbiology, 2020
Planktonic heterotrophic diazotrophs (N2-fixers) are widely distributed in marine and freshwater systems, yet limited information is available on their activity, especially in environments with adverse conditions for diazotrophy (e.g., N-rich and ...

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 ...

Defining the Realized Niche of the Two Major Clades of Trichodesmium: A Study on the West Florida Shelf

Frontiers in Marine Science, 2022
The cyanobacterium Trichodesmium plays an essential role supporting ocean productivity by relieving nitrogen limitation via dinitrogen (N2) fixation. The two common Trichodesmium clades, T. erythraeum and T.

Spatial variation in N₂-fixation rate and diazotroph activity in the Tropical Atlantic [PDF]

Biogeosciences, 2007
A variety of N2-fixers occur in oligotrophic waters and these diazotrophs make a substantial contribution to the nitrogen budget of the upper water column.
