Summary
Plants are constantly exposed to abiotic stresses such as drought, salinity, extreme temperatures, nutrient imbalances, and heavy metal contamination, all of which significantly affect growth, productivity, and ecosystem stability. These challenges are further intensified by climate change and increasing environmental pollution. To cope with such conditions, plants have evolved complex adaptive mechanisms involving physiological, biochemical, and molecular responses, including stress perception, signaling pathways, osmotic adjustment, and activation of antioxidant defenses. Understanding these processes is essential for improving plant resilience and ensuring sustainable agricultural systems.
At the same time, phytoremediation has emerged as a sustainable and cost-effective strategy to mitigate environmental contamination. By leveraging the natural ability of plants to accumulate, transform, or stabilize pollutants, phytoremediation contributes to restoring degraded ecosystems while maintaining ecological balance. Integrating plant stress biology with phytoremediation research offers new opportunities for addressing both agricultural and environmental challenges.
This Special Issue aims to highlight recent advances in the understanding of plant responses to abiotic stress and their application in phytoremediation. We welcome original research, reviews, and perspectives that explore underlying mechanisms and innovative approaches, with particular emphasis on interdisciplinary studies and emerging technologies.
