Supporting evidence — 4 representative gaps

• Linking Molecular Diversity to Electron Transfer Capacity of Soil Dissolved Organic Matter: Role of Molecular Composition and Structure (2025) · Environmental Science & Technology · cited 23× · doi

  Soil dissolved organic matter (DOM) plays a pivotal role in various environmental redox processes due to its abundant redox active functional groups, but how the molecular diversity of soil DOM regulates its redox capacity remains poorly understood.

• Water-fertilizer strategies regulate greenhouse gas dynamics along the soil profile: Horizon differentiation driven by coupled responses of dissolved organic matter and archaeal communities (2026) · Agricultural Water Management · cited 1× · doi

  However, existing evidence has mostly focused on surface fluxes, and the regulatory mechanisms by which dissolved organic matter (DOM) and microorganisms jointly affect GHG production and emission remain poorly understood.

• Dissolved organic matter fosters core mercury-methylating microbiomes for methylmercury production in paddy soils (2025) · Biogeosciences · cited 18× · doi

  Its production is largely driven by microbial methylation in paddy soils; however, dissolved organic matter (DOM) is a critical component of the soil biogeochemistry process, yet its interactions with microorganisms involved in MeHg production remain poorly understood.

• Microbial community regulation of spectral and molecular characteristics of soil dissolved organic matter in typical heavy metal-contaminated soil (2026) · Environmental Earth Sciences · doi

  However, it remains unclear whether different types of industrial pollution leave distinct molecular fingerprints on soil dissolved organic matter (DOM) and whether such patterns are driven by specific microbial mechanisms.
