This book compiles 15 articles, including one review, one brief report, and thirteen original papers, exploring plant responses to environmental stresses. It provides insights into the complex mechanisms plants use to adapt to abiotic stresses such as drought, salinity, and temperature extremes. The studies cover a wide range of plant species, including model plants like Arabidopsis, crops like cotton and wheat, and ornamental plants. The research focuses on physiological, biochemical, and molecular traits, such as photosynthetic activity, root system architecture, and stress-responsive gene expression. The book also highlights the importance of root traits in plant adaptation under water-limited conditions and discusses the role of various genes in stress responses. The findings contribute to understanding plant responses to environmental stresses and have implications for breeding programs aimed at improving crop resilience. The book is a valuable resource for researchers and practitioners in plant biology and agriculture.This book compiles 15 articles, including one review, one brief report, and thirteen original papers, exploring plant responses to environmental stresses.
