Mechanistic insights into plant-derived biostimulants for sustainable agriculture and stress tolerance

Phytohormone and nanoparticle crosstalk as a unified mechanistic paradigm for sustainable plant stress management

Biotic and abiotic stressors, including climate crises, are affecting plants’ metabolic and developmental processes, which negatively influence crop performance and the overall resilience of agroecosystems. In response to these stressors, plants have evolved multifaceted defense mechanisms at morphological, physiolog...

Plant-derived and microbial biostimulants in sustainable agriculture: mechanisms, applications, and challenges

Cyanobacteria in sustainable agriculture: from bioactive metabolites toward mechanistically validated biostimulants

Cyanobacteria are emerging as multifunctional components of sustainable agroecosystems, with the potential to influence nutrient cycling, soil structure, plant-associated microbiomes, and crop responses to environmental stress. This review integrates current knowledge of the molecular and physiological mechanisms under...

Towards a Mechanistic Convergence Framework for Plant Biostimulant Activity: A Review of Insights from Molecular Signalling, Multi-Omics and Plant Physiology

A mechanistic convergence framework is proposed to explain how structurally distinct plant biostimulants may influence overlapping regulatory networks controlling plant growth and environmental adaptation and provides a conceptual basis for the rational development of evidence-based precision biostimulants for sustaina...

Endophytes for climate-resilient agriculture: Mechanisms and systems-level insights.

Endophytic bacteria and fungi that asymptomatically colonise plant tissues represent promising biological resources for developing sustainable and climate-resilient agricultural systems. These beneficial microorganisms establish intimate associations with crops and modulate plant growth, nutrient acquisition, immune re...

Plant Growth-Promoting Rhizobacteria as Sustainable Bioinoculants for Mitigating Climate-Induced Abiotic Stresses
