The interaction between plant signaling molecules and nanotechnology is advancing new avenues in crop enhancement and stress resilience. In recent years, the agricultural sector has faced significant challenges due to abiotic stresses such as drought, salinity, and extreme temperatures, which adversely affect crop productivity. Traditional methods of mitigating these stresses have shown limited success, prompting the need for innovative solutions. Recent studies have demonstrated that nanomaterials, when combined with plant compounds and signaling molecules, can significantly enhance plant biochemical and physiological responses to these stresses. However, the integration of these elements remains underexplored, and there is a pressing need for comprehensive research to fully understand their synergistic potential and practical applications in sustainable agriculture.

This research topic aims to provide a comprehensive understanding of how nanomaterials, in conjunction with plant compounds and signaling molecules, can substantially augment plant biochemical and physiological responses to abiotic stress and enhance crop productivity. By highlighting interdisciplinary research that integrates these elements, we underscore the synergistic potential of plant compounds, signaling molecules, and nanomaterials in fostering crop resilience and productivity. This issue offers insights into innovative strategies for sustainable agriculture, inspiring further innovation and practical applications at this critical intersection.
