Glutathione is one of the most versatile and indispensable biomolecules in plants and has classically been described as a cellular antioxidant. As a central regulator of redox homeostasis, metabolism, and signaling, glutathione orchestrates numerous physiological processes that underpin plant growth, productivity, and resilience. Over the past decade, advanced molecular and systems-based approaches have uncovered additional layers in glutathione-mediated regulation. With changing climatic conditions, research on glutathione has become an essential prerequisite for developing novel sustainable agricultural strategies. This edited volume presents a comprehensive and authoritative overview of contemporary advances in plant glutathione research. A striking feature is its integration of fundamental concepts in the field with translational perspectives. The book is organized into five thematic sections, beginning with the biochemical foundations of glutathione, its structure, and synthesis, through its role in regulating plant development, nutrient homeostasis, nitrogen fixation, stress responses, and finally the advanced omics- and nanotechnology-based approaches that can pave the way for new avenues in crop improvement. The book serves not only as a reference for researchers and academics but also as a significant resource for graduate students, plant biologists, agronomists, biotechnologists, and professionals interested in applying redox biology to agricultural advancement.
