Supporting evidence — 7 representative gaps

• Soil Microorganisms: Their Role in Enhancing Crop Nutrition and Health (2024) · Diversity · cited 192× · doi

  the impacts of global environmental changes and intensive agricultural practices on the diversity of microorganisms remain a critical gap in the literature, - the complexity of soil environments gives rise to a vast diversity of soil microorganisms, - functional redundancy complicates our understanding of the specific contributions of individual species to soil health and plant growth

• Mixed-Planting Mode Is Associated with Distinct Bacterial and Fungal Assembly Patterns in Pinus sylvestris var. mongolica Plantations (2026) · Diversity · doi

  The differences among mixed-planting modes in terms of microbial diversity, community composition, and assembly processes are not well understood. The responses of bacterial and fungal communities to mixed-planting modes are not well characterized.

• Community structure of soil microorganisms and endophytes of honeysuckle at different ecological niche specificities (2024) · BMC Microbiology · cited 5× · doi

  However, the complexity of microbial diversity in plant microenvironments in different regions, especially the relationship between subsurface and aboveground microorganisms, is not fully understood.

• Mechanistic Insights into the Role of Endophytic Fungi in Combating Salinity and Insect Stress in Plants (2026) · Journal of Crop Health · doi

  Results obtained under controlled laboratory and greenhouse conditions frequently exhibit limited reproducibility under field environments. Gnotobiotic and sterile experimental systems oversimplify ecological complexity by ignoring interspecies competition and native microbial communities. Environmental heterogeneity, varying climatic factors, soil physicochemical variability, and complex native microbial interactions limit the wider applicability of experimental results.

• Habitat-Dependent Ecological Differentiation of Soil and Water Microbiomes in High-Altitude Alpine Meadow Ecosystems on the Qinghai–Tibetan Plateau (2026) · Microorganisms · doi

  Previous research has largely been confined to soil ecosystems, leaving a gap in understanding the ecological differentiation of soil and water microbiomes. There is a lack of understanding of how environmental heterogeneity influences the ecological assembly processes governing soil and water microbiomes.
