Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates (2012, methodology): “…di ﬀ erent groups of heterocystous cyanobacteria based on three nifH gene sequences (het-1, het-2 and het-3), which have been identiﬁed in symbioses with diatoms: Richelia - Rhizosolenia , Richelia - Hemiaulus and Calothrix - Chaetoceros , respectively (Church et al., 2005b; Foster and Zehr, 2006).”
Experiments linking nitrogenase gene expression to nitrogen fixation in the North Pacific subtropical gyre (2007, methodology): “The Group A daily expression pattern in the present study and that of Church et al. (2005b) contradict the pattern described by Falcón et al. (2004b), who reported that a Pacific Ocean unicellular cyanobacteria isolate was a Group A type and fixed nitrogen during the dark period.”
Nutrient limitation of primary productivity in the Southeast Pacific (BIOSOPE cruise) (2007, methodology): “DNA was extracted from the filters (Church et al., 2005) with the addition of a beadbeating step prior to the lysis step.”
Regional distributions of nitrogen‐fixing bacteria in the Pacific Ocean (2008, methodology): “All the phylotypes targeted by QPCR had been reported from nifH RT-PCR clone libraries in the North Pacific Ocean (Zehr et al. 1998, 2001; Church et al. 2005b).”
Nitrogen fixation in the western equatorial Pacific: Rates, diazotrophic cyanobacterial size class distribution, and biogeochemical significance (2009, background): “Unicellular diazotrophic cyanobacteria have been described so far to be of nanoplanktonic size (3–10 mm) and to be related to Crocosphaera or Cyanothece [Zehr et al., 2001; Church et al., 2005; Foster et al., 2006].”
Diversity and activity of nitrogen‐fixing communities across ocean basins (2017, methodology): “Study sites and sampling strategy Diazotrophic diversity and NFR were assessed in (1) the ESP (Center for Microbial Oceanography: Research and Education cruise aboard the R/V Melville, Biogeochemical Gradients: Role in Arranging Planktonic Assemblages [BIG RAPA], November to December 2010), (2) the ”
The Mekong River plume fuels nitrogen fixation and determines phytoplankton species distribution in the South China Sea during low and high discharge season (2010, background): “…to host other groups of N2-fixing organisms than the typical open-ocean diazotrophs Trichodesmium and unicellular cyanobacteria (Capone et al. 1997; Church et al. 2005a); for example, in the Amazon River plume, diatom–diazotroph associations (DDAs) can displace Trichodesmium as the dominant…”
Diazotrophic diversity, nifH gene expression and nitrogenase activity in a rice paddy field in Fujian, China (2009, background): “However, few studies have previously been performed on soil where qPCR is combined with reverse transcriptase (RT) PCR, enabling in vitro quantification of specific gene expression (Cook and Britt 2007; Jacobsen and Holben 2007) and qRT-PCR applied to the field emerge as a powerful tool for quantifi”
Influence of the Amazon River plume on distributions of free‐living and symbiotic cyanobacteria in the western tropical north Atlantic Ocean (2007, methodology): “We used the het1 TaqMan primer and probe previously described by Church et al. (2005a) because we obtained nifH sequences identical to those of Church et al. (2005a) from Richelia associated with R. clevei (Table 1) (Foster and Zehr 2006).”
The Black Queen Hypothesis: Evolution of Dependencies through Adaptive Gene Loss (2012, background): “However, it is performed by a relatively small subset of organisms; for example, in the oceans, nitrogen-fixing species (diazotrophs) constitute less than 1% of the total cyanobacterial population (40).”
Seasonality of N2 fixation and nifH gene diversity in the Gulf of Aqaba (Red Sea) (2009, background): “These included primers and probes for the nifH gene of the unicellular groups B and C, and three heterocystous symbionts of diatoms (het-1, het-2, het-3) (Church et al. 2005a; Foster et al. 2007).”
New insights into the ecology of the globally significant uncultured nitrogen-fixing symbiont UCYN-A (2016, methodology): “These results suggest that sublineages that would not have been detected using the Church et al. (2005a) qPCR assay may be prevalent in some environments and could account for significant N2 fixation.”
Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean (2007, methodology): “Church et al. (2005b) measured a daytime average of two nifH mRNA copies per cell for the group A phylotypes at ALOHA.”
