Plant Physiology is a field that is constantly evolving and expanding our understanding of fundamental plant processes. The past decade has seen remarkable advancements in the biological sciences due to the introduction of cutting-edge technologies like recombinant DNA techniques, omics approaches, and advanced phenotyping platforms.

These innovations have challenged and redefined many previously established concepts in plant life. This publication aims to shed light on lesser-known signals that can affect plant growth and development. A solid foundation in plant physiological processes is essential for research in related fields such as crop improvement, crop production, and crop protection.

As the push for sustainable agriculture grows, the information presented in this book can encourage researchers to develop environmentally friendly and non-chemical methods for enhancing crop production, while also harnessing the inherent abilities of plants to improve their performance in the field.
