Plant development and growth are coordinated by a multifaceted network of signaling pathways and hormones. This session addresses the functions of auxins, gibberellins, cytokinins, and abscisic acid in modulating growth processes. Learners will discover how ethylene, jasmonic acid, and salicylic acid regulate defense and developmental responses. The session emphasizes the molecular signaling pathways that link hormones to plant physiology. Scientists will discuss research on crosstalk between hormones during seed germination, flowering, and root development. Participants will learn about genetic and molecular control of hormone response. Case studies will demonstrate how the manipulation of hormone balance increases crop yield and sustainability. Biotechnological intervention in hormonal regulation to enhance optimization will also be discussed. Participants will learn about how hormone-driven growth models are applied to developmental biology. This seminar combines plant physiology, molecular biology, and agricultural applications to give a holistic overview of hormones in plant science and plant improvement.
