Plant Hormones and Growth Regulators: Coordination of Development and Stress Responses | Chapter 20 of Plant Physiology and Development
Plant Hormones and Growth Regulators: Coordination of Development and Stress Responses | Chapter 20 of Plant Physiology and Development Chapter 20 of Plant Physiology and Development provides a comprehensive overview of plant hormones and growth regulators—small signaling molecules that orchestrate nearly every aspect of plant life. These chemical messengers integrate environmental cues with developmental programs, influencing processes such as cell division, elongation, senescence, dormancy, germination, and stress responses. The chapter explains how classical hormones like auxins, cytokinins, gibberellins, abscisic acid (ABA), and ethylene interact with newer regulators including brassinosteroids, jasmonates, salicylic acid, strigolactones, and peptide hormones. The video below offers a clear, structured summary of these pathways and their functional significance.
