Fig. 5: Methanoregula presence and activity are important predictors of methane flux.
From: Metabolic interactions underpinning high methane fluxes across terrestrial freshwater wetlands
a A linear regression comparing the residual values from the methane flux to the temperature trend line showed a significant positive relationship to the relative abundance of Methanoregula within the methanogen community. b Genome tree of Methanoregula MAGs from MUCC (OWC, PPR, STM), plus available MAGS from JGI and GTDB (n = 149 Methanoregula MAGs). A pangenome analysis shows the largely conserved encoding of genes for key physiological features, as well as limited novel metabolic potential (e.g., methylotrophic genes) which may directly or indirectly support high methane fluxes from Methanoregula in wetlands. c Mean transcription of top five most active methanogenic genera at three depths (0–5 cm, 10–15 cm, 20–30 cm) in the mud site type across the 2018 sampling season predictive of CH4 fluxes (n = 43 metatranscriptomes).
