soil-dwelling

Edge evidence

• soil habitat enables soil-dwelling RO:0002327

  Soil substrate and pore-water chemistry sustain soil-resident microbes.

  • DOI:10.1038/nrmicro.2017.87 Fierer characterizes the soil microbiome as a distinct microbial habitat.
• soil-dwelling contributes to biogeochemical cycling RO:0002326

  Soil microbes drive terrestrial biogeochemical cycling.

  • DOI:10.1038/nrmicro1341 Martiny et al. show soil communities are biogeographically structured habitats central to ecosystem function.
• low available organic carbon enriches for oligotrophic lifestyle

  Carbon-limited soils enrich oligotrophic taxa with small genomes and reduced motility/chemotaxis.

  • DOI:10.1093/ismeco/ycae081 Dragone et al.: oligotroph-enriched taxa in carbon-limited soils had smaller genomes, slower growth, carbon-storage pathways, and under-represented chemotaxis/motility genes.
• soil resource availability and moisture increases soil microbiome potential growth rate RO:0002213

  Resource-rich, humid, acid-neutral soils support higher microbiome potential growth.

  • DOI:10.1038/s41467-024-53753-w Zhou et al.: high potential growth in resource-rich, acid-neutral soils of cold, humid regions (18O-H2O DNA incorporation).
• soil aridity decreases soil microbiome potential growth rate RO:0002212

  Aridity lowers soil microbiome potential growth rate.

  • DOI:10.1038/s41467-024-53753-w Zhou et al.: aridity was a stronger predictor of community growth than temperature; dry soils had lower potential growth.
• high soil carbon availability increases prevalence of flagellar motility

  High soil carbon availability raises prevalence of flagellar motility.

  • DOI:10.1093/ismejo/wrae067 Ramoneda et al.: rhizosphere ~11.5% higher flagellar prevalence (P=0.012); glucose amendment increased prevalence (P=0.017).
• extreme climatic event increases dormancy and sporulation gene program RO:0002213

  Heat, flood and freeze extremes increase dormancy and sporulation gene abundance.

  • DOI:10.1038/s41586-024-08185-3 Knight et al.: dormancy and sporulation genes increased across flood, freeze and heat; 46% of annotated genes shifted at disturbance end.
• soil pH, precipitation and C:N predicts soil bacterial life-history strategy axes

  Soil pH, precipitation and C:N predict soil bacterial life-history genomic axes.

  • DOI:10.1038/s41564-023-01465-0 Piton et al.: random-forest models using pH, precipitation and C:N predicted MCOA1/MCOA2 (R2=0.80, 0.58); pH and precipitation top predictors.
