Plant Physiology and Auxin Hormone Signalling

Understanding how plants coordinate their growth in response to the environment is a cornerstone of plant biology. Auxin is the primary hormone driving these processes, controlling everything from cell elongation to root development. This course provides a clear, step-by-step exploration of auxin physiology, breaking down complex molecular pathways into accessible, written explanations. You will transition from basic biological concepts to a comprehensive understanding of hormone behavior, transport systems, and signaling networks. What you will learn: Understand the chemical structure and biosynthesis pathways of auxin; Analyze the mechanisms of polar auxin transport across plant tissues; Master the molecular signaling pathways, including receptor interactions and gene expression; Explain how auxin regulates phototropism, gravitropism, and apical dominance; Explore modern research techniques used to study plant hormones today. We begin with essential terminology and the foundational biochemistry of plant hormones before moving into detailed transport models and cellular signaling pathways. This text-based course is designed for beginning biology students, agriculture enthusiasts, and anyone curious about plant physiology, requiring no advanced background in biochemistry. Start reading today to unlock the secrets of plant growth regulation.
