• Sterols and other triterpenoids: source specificity and evolution of biosynthetic pathways (2005, background): “For example, success has already been achieved with the identification and quantification of genes coding for various steps in the nitrogen cycle in sediments (e.g. MacGregor et al., 2001; Zehr et al., 2003).”
• Plant growth-promoting bacteria as inoculants in agricultural soils (2015, background): “trophics, as well as an enormous variability of environments where they can be found, they all contain the enzyme nitrogenase (Moat and Foster, 1995; Boucher et al., 2003; Zehr et al., 2003; Dixon and Kahn, 2004).”
• Plant Biostimulants: A Categorical Review, Their Implications for Row Crop Production, and Relation to Soil Health Indicators (2021, background): “There are three types of nitrogenase enzyme complexes that differ in their metal cofactor: iron-iron (Fe-Fe), molybdenum-iron (Mo-Fe), or vanadium-iron (V-Fe) [61].”
• Diversity and activity of nitrogen‐fixing communities across ocean basins (2017, methodology): “Translated OTUs were classified into canonical nifH gene clusters (Zehr et al. 2003b) using BLAST-p similarity to a reference database of nifH sequences previously assigned to nifH groups (http://www.jzehrlab.com/#!nifh-database/ c1coj).”
• Burrowing deeper into benthic nitrogen cycling: the impact of bioturbation on nitrogen fixation coupled to sulfate reduction (2010, result): “…only those species that were a close match within the cluster to the Catalina samples are shown. nifH cluster designations assigned according to Zehr et al. (2003) Mar Ecol Prog Ser 409: 1–15, 201010 denitrification (Gilbert et al. 1995, 1998, Herbert 1999), our results from Catalina Harbor…”
• Biodiversity of diazotrophic bacteria within the soil, root and stem of field-grown maize (2007, background): “Considering that nitrogenase genes cluster into four basic groups, previously designated as Clusters I–IV ( Zehr et al. 2003 ), and represent only a fraction of the whole community, diversity estimates of one cluster requires much reasonable sampling and sequencing effort.”
• Diazotrophic bacteria associated with Hawaiian Montipora corals: Diversity and abundance in correlation with symbiotic dinoflagellates (2009, neutral): “The nifH gene displays a relatively high sequence variability level similar to that of 16S and has been commonly used in diversity studies of N-fixing bacteria (Zehr et al., 2003).”

• Diazotrophic diversity, nifH gene expression and nitrogenase activity in a rice paddy field in Fujian, China (2009, background): “In analysis of the indigenous diazotophic community in diverse environments, the nifH gene, encoding the dinitrogenase reductase part of the nitrogenase complex, is a commonly used marker for studying the diazotrophic assemblage and gene activity in different ecosystems (Zehr et al. 2003).”
• Genetic diversity and potential for promotion of plant growth detected in nodule endophytic bacteria of soybean grown in Heilongjiang province of China (2008, background): “Kuklinsky-Sobral et al. (2004) reported that nifH was not able to be amplified from some nitrogen-fixing bacteria, and the failure of amplification of nifH may be the result of variability of this gene (Zehr et al., 2003).”
• Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean (2007, background): “Characterization of planktonic nifH genes (the gene that encodes the iron subunit of nitrogenase, the enzyme responsible for N2 fixation) has proven useful for identifying uncultivated diazotrophic microorganisms (Zehr et al. 2003).”
