Last Minute Lecture

Signal Transduction Pathways, Plant Receptors, and Cellular Communication Explained | Chapter 15 of Plant Physiology and Development Chapter 15 of Plant Physiology and Development examines the complex signaling systems plants use to detect internal and external cues and translate them into precise physiological responses. Signal transduction forms the foundation of plant communication, allowing cells to perceive environmental changes, hormones, pathogens, mechanical forces, and developmental cues. This chapter provides a detailed breakdown of receptors, second messengers, protein kinases, transcriptional regulators, and the sophisticated feedback loops that ensure specificity and adaptability in plant signaling. Watch the complete Last Minute Lecture lesson below for a clear and accessible summary of these mechanisms.
