In the era of climate change, the resilience of crop plants is vital for global food security. and #60;i and #62;Abiotic Stress in Crop Plants - Ecophysiological Responses and Molecular Approaches and #60;/i and #62; addresses the challenges posed by stressors like extreme temperatures, drought, salinity, and flooding. This comprehensive volume features 13 chapters that explore ecophysiology and plant responses to environmental stress, adaptation mechanisms, strategies plants use to survive under adverse conditions, and genetic and molecular bases of stress tolerance. By integrating these areas, the book offers a holistic view of plant responses to abiotic stress, compiling recent advancements and cutting-edge research. It is an essential resource for scientists, researchers, and students dedicated to enhancing crop resilience and promoting sustainable agriculture.
