Nitric Oxide in Plant Growth, Development and Stress Physiology

Recent advances in the study of nitric oxide (NO) biology, biochemistry, molecular biology and physiology in plants are presented in this book, providing an overview of current understanding of the NO actions involved in adaptive responses of plant fitness to environmental constraints. The special emphasis is on NO-dependent signalling, molecular adjustments and targets as key elements in plant growth, development and stress physiology.

The first part of the book is devoted to the description of key features related to NO biochemistry, synthesis and metabolism and the modes of action involved. The second part covers the functionality of NO in three central nodes of the plant life cycle: growth, development and stress physiology. Finally, a detailed analysis of the advantages and disadvantages of the use of fluorometric detection of NO in plant research brings to light information necessary for understanding the limitations of the method.

Auteur

All authors are the most authoritative and competent scientists in the field of NO as a key player in plant physiological processes. Drs. Delledonne, Durner, Wendehenne and Lamattina have, among others, authored landmark publications in the extraordinary up swelling studies on NO actions in plant biology. Drs. Kaiser and Stohr have an extensive trajectory in the study of N metabolism in plants, and the roles/actions of nitrate reductase/nitrite reductase. Their contributions to understand the origin and functions of NO at both the tissues and the subcellular levels have been remarkable. Drs. Jones, Puntarulo and Konjevic have made extraordinary contributions to decipher the role of endogenous NO, its sources and physiological concentrations in seed germination and dormancy breaking. Drs. Scherer, Blatt and Lamattina have made extensive contributions to our understanding of the cross talk between classical plant hormone actions and NO involvement in their signaling mechanisms. Drs. Delledonne, Corpas, Shapiro, Salgado and Hill, and their colleagues have presented pioneering reports on the involvement of NO in plant responses to diverse (a)biotic stress situations, particularly during the hypersensitive response (HR). Finally, the authoritative contribution of Dr. Yamasaki to integrate aspects of NO generation, metabolism and detection in plants has been an important impetus and has lead to new theories on the role of NO in N, C and S metabolism in plants and in the interaction with the environment.
