Strigolactones: Synthesis, Application and Role in Plants presents the current state of the science for this recently discovered class of plant hormones, offering foundational insights. The book covers the structure of natural and synthetic SLs, synthesis, transport, signaling, and their application, role in the growth and development of plants like seed germination, root growth, and stem branching plant architecture. Further, the crosstalk of SLs with other plant hormones and signaling molecules are discussed. Finally, the role of SLs in plant defense systems, particularly in biotic and abiotic stresses, heavy metals, salt, temperature, radiation, pesticide drought, and flood stress on plants. Concluding with the latest discoveries, future perspectives, and challenges in plant biology, this book will be a valuable reference for those in plant and agricultural sciences.
