Summary
Climate change is increasingly reshaping the global agricultural landscape, posing significant threats to the growth, productivity, and sustainability of crops. Abiotic stress factors such as drought, salinity, extreme temperatures, and heavy metal contamination are some of the major factors that influence agricultural productivity. These stressors often occur in conjunction with biotic pressures, including pathogens, pests, and invasive weeds, further complicating plant survival and productivity. Lants cope with environmental stress through changes in their physiology, biochemistry, and molecular mechanisms. A key aspect of stress adaptation involves managing oxidative stress, commonly triggered by the overproduction of reactive oxygen and nitrogen species (ROS and RNS). To mitigate oxidative damage, plants activate an intricate defense system comprising enzymatic and non-enzymatic antioxidants, along with the enhanced synthesis of compatible solutes that provide both antioxidant and osmoprotective functions.
This Special Issue invites original research and reviews on innovative approaches to understanding and enhancing plant tolerance to abiotic stresses. We welcome contributions that delve into the underlying mechanisms of plant resilience at the morphological, physiological, biochemical, and molecular levels. Emphasis will be placed on cutting-edge technologies, integrative approaches, and novel insights that drive the development of stress-resilient cultivars and nature-based solutions.
Topics of interest for this Special Issue include, but are not limited to:
· Stress physiological and biochemical responses
· Antioxidant defense and ROS management
· Phytohormonal regulation and signaling
· Metabolic reprogramming under stress
· Gene expression and enzyme modulation
· Multi-stress interactions and cross-tolerance
· Applications of bio-stimulants in abiotic stress management
