Abiotic Stress Physiology

Abiotic stress physiology examines how plants respond to non-living environmental factors such as drought, salinity, temperature extremes, and nutrient deficiencies. These stressors can significantly impair plant growth and productivity. Plants have developed various physiological adaptations to mitigate these effects, including alterations in root architecture to enhance water uptake, changes in leaf morphology to reduce transpiration, and the accumulation of stress-responsive proteins. Signal transduction pathways, particularly those involving plant hormones like abscisic acid, play critical roles in mediating these responses. Understanding the physiological mechanisms of abiotic stress tolerance is essential for developing resilient crop varieties in the face of climate change.
