Supporting evidence — 6 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

  There is a lack of understanding of how rhizosphere-driven differences in carbon impact denitrification in different soil compartments. The study identifies a gap in knowledge regarding the role of carbon availability in mediating denitrification potential in the rhizosphere of intercropped plants.

• 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.

  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.

• Plant domestication shapes rhizosphere microbiome assembly and metabolic functions (2023) · Microbiome · cited 258× · doi

  Despite its importance, how plant domestication builds up specific rhizosphere microbiomes and metabolic functions, as well as the importance of these affected rhizobiomes and relevant root exudates in maintaining plant growth, is not well understood.
