nifH gene expression and diversity in geothermal springs of Tengchong, China [PDF]
Terrestrial hot springs have been suggested to harbor diverse diazotrophic lineages by using DNA-based nifH gene phylogenetic analysis. However, only a small amount of diazotrophs were ever confirmed to perform nitrogen fixation.

A comprehensive evaluation of PCR primers to amplify the nifH gene of nitrogenase. [PDF]
The nifH gene is the most widely sequenced marker gene used to identify nitrogen-fixing Bacteria and Archaea. Numerous PCR primers have been designed to amplify nifH, but a comprehensive evaluation of nifH PCR primers has not been performed. We performed

Seasonal and long-term effects of nutrient additions and liming on the nifH gene in cerrado soils under native vegetation [PDF]
Summary: Biological nitrogen fixation (BNF) represents the main input source of N in tropical savannas. BNF could be particularly important for Brazilian savannas (known as Cerrado) that show a highly conservative N cycle.

Exploration of nifH gene through soil metagenomes of the western Indian Himalayas [PDF]
This group has previously highlighted the prevalence of Csp genes from cold Himalayan environments. However, this study has explored the uncultured diazotrophs from metagenomes of western Indian Himalayas.

The Flora Compositions of Nitrogen-Fixing Bacteria and the Differential Expression of nifH Gene in Pennisetum giganteum z.x.lin Roots [PDF]
The flora compositions of nitrogen-fixing bacteria in roots of Pennisetum giganteum z.x.lin at different growth stages and the expression and copy number of nitrogen-fixing gene nifH were studied by Illumina Miseq second-generation sequencing technology ...

The Abundance of the nifH Gene Became Higher and the nifH-Containing Diazotrophic Bacterial Communities Changed During Primary Succession in the Hailuogou Glacier Chronosequence, China [PDF]
Primary successional ecosystems and the related soil development are often N limited. To date, N2-fixing communities during primary succession in alpine ecosystems have remained underexplored.

Molecular evidence for sediment nitrogen fixation in a temperate New England estuary [PDF]
Primary production in coastal waters is generally nitrogen (N) limited with denitrification outpacing nitrogen fixation (N2-fixation). However, recent work suggests that we have potentially underestimated the importance of heterotrophic sediment N2 ...

Genetic analysis of the NifM dependence of the nitrogenase iron proteins [PDF]
NifH maturation in certain diazotrophic bacteria depends on NifM, a protein with a PpiC-isomerase domain. Intriguingly, the putative proline substrate for NifM is present in NifH proteins from strains lacking nifM, raising questions regarding the actual ...

ANALISIS AKTIVITAS NITROGENASE DAN GEN NIFH ISOLAT BAKTERI RHIZOSFER TANAMAN PADI DARI LAHAN SAWAH PESISIR JAWA BARAT [PDF]
Abstrak Penambatan nitrogen oleh bakteri rhizosfer dapat dimanfaatkan untuk menyiasati dampak salinitas pada tanah sawah pesisir. Kemampuan tersebut disebabkan oleh aktivitas nitrogenase yang disandikan gen nifH pada komponen II.

Effects of reduced nitrogen on the nifH-harboring soil microbiome in a soybean-maize strip intercropping system [PDF]
IntroductionNitrogen (N) is a core limiting factor for crop growth, with approximately 50% of global food production relying on chemical N fertilizer inputs.
