Supporting evidence — 8 representative gaps

• Rhizosphere biogeochemical process drives yttrium immobilization during phytoremediation with microbe-organic amendments (2026) · Plant and Soil · doi

  The biogeochemical process in the rhizosphere is underexplored in the context of phytoremediation. There is a need to understand the effects of bio-organic fertilizer and plant growth-promoting microorganisms on yttrium immobilization.

• Appropriate Nitrogen Addition Boosts Coastal Wetland Carbon Sequestration: Kandelia obovata Optimizes Microbial Carbon Use Strategies (2026) · Plants · doi

  The paper identifies a gap in understanding the microbial metabolic mechanisms underlying soil carbon sequestration in Kandelia obovata systems under exogenous nitrogen input. The study aims to fill this gap by exploring the effects of nitrogen addition on carbon sequestration in Kandelia obovata ecosystems.

• Carbon availability mediates differences in rhizosphere denitrification potential between intercropped plants (2026) · Frontiers in Sustainable Food Systems · cited 1× · doi

  The study only considered a two-year field experiment. The study did not account for other potential drivers of denitrification, such as anaerobicity. The study only considered a limited number of plant species.

• Enhancing the Resilience of Agroecosystems Through Improved Rhizosphere Processes: A Strategic Review (2024) · International Journal of Molecular Sciences · cited 29× · doi

  The interactions between beneficial microbes and plants in the rhizosphere remain inadequately understood. The impact of green manures and intercropping on rhizosphere processes is not fully explored. The development of sustainable cropping systems that can address climate challenges is a pressing need.

• Root exudate chemistry affects soil carbon mobilization via microbial community reassembly (2022) · Fundamental Research · cited 172× · doi

  Although rhizodeposition regulates both microbial activity and the biogeochemical cycling of nutrients, the effects of particular exudate species on soil carbon fluxes and key rhizosphere microorganisms remain unclear.

  Further research is needed to understand how the rhizosphere effect on denitrification varies between different plant species and communities. Studies should investigate the role of other potential drivers of denitrification, such as anaerobicity. Research should focus on developing strategies to manage ecosystems to produce less N2O.
