Nitrogen Fixation and Translocation in Sugarcane [PDF]
, 2008 World sugarcane production is increasing rapidly as a biofuel. In some areas in Brazil, sugarcane has been grown continually over very long periods without N fertiliser inputs. Therefore, the occurrence of N fixation has been suspected.

Plant, Cell &Environment, EarlyView.ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

Long-Term Warming in Alaska Enlarges the Diazotrophic Community in Deep Soils
mBio, 2019 Tundra ecosystems are typically carbon (C) rich but nitrogen (N) limited. Since biological N2 fixation is the major source of biologically available N, the soil N2-fixing (i.e., diazotrophic) community serves as an essential N supplier to the tundra ...

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

Hopanoid lipids may facilitate aerobic nitrogen fixation in the ocean. [PDF]
, 2019 Cyanobacterial diazotrophs are considered to be the most important source of fixed N2 in the open ocean. Biological N2 fixation is catalyzed by the extremely O2-sensitive nitrogenase enzyme.

Direct and indirect costs of dinitrogen fixation in Crocosphaera watsonii WH8501 and possible implications for the nitrogen cycle [PDF]
, 2012 The recent detection of heterotrophic nitrogen (N2) fixation in deep waters of the southern Californian and Peruvian OMZ questions our current understanding of marine N2 fixation as a process confined to oligotrophic surface waters of the oceans.

Diazotroph‐Driven 210Po Scavenging Reveals a Potential Radiotracer for Marine Nitrogen Fixation
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract The role of phytoplankton, particularly diazotrophs, in affecting in situ 210Po scavenging has been little investigated. Here, we first report an enhanced 210Po deficit in a cyclonic eddy core relative to its edge in the subtropical Pacific, coinciding with an elevated integrated nitrogen fixation rate (NFR).

Effect of Hydrolytic Enzymes Production by Diazotrophs and Urea Fertilization on Root Colonization and Growth of Rice (Oryza Sativa L.) [PDF]
, 2010 Production of hydrolytic enzyme by diazotrophs and their association with rice plant may increase the N2-fixing activity and subsequently plant growth. The ability to produce hydrolytic enzymes is an important mechanism of diazotrophs to enter the plant ...
