Book excerpt: J.W. Mitchell, N.B. Mandava and others' 1970 publication in Nature, "Brassins-A New Family of Plant Hormones from Rape Pollen" announced the discovery of a new plant hormone, brassinolide, which would also mark the sixth and newest group of plant hormones, brassinosteroids. This monograph details the early research leading to the isolation and synthesis of the first brassinosteroid to current research in the field. The 50 years of brassinosteroid research can be separated in two parts; The first 25 years saw the innovation of different bioassays and isolation techniques while the last 25 years saw the investigation into brassinosteroids signaling, cross talk, stress response, and agricultural application. Since the discovery of brassinolide, there have now been 62 brassinosteroids identified through international research efforts. Several of these have been targeted for agricultural use with patents in many countries. Homobrassinolide is one such brassinosteroid that helps improve crop yield and fruit sweetness while conferring stress resistance. This monograph is the first to fully encompass the story of brassinosteroids.

Available in PDF, EPUB and Kindle. Book excerpt: The entire range of the developmental processes in plants is regulated by the shift in the hormonal concentration, tissue sensitivity and their interaction with the factors operating around the plants. Out of the recognized hormones, attention has largely been focused on five (Auxins, Gibberellins, Cytokinin, Abscisic acid and Ethylene). However, in this book, the information about the most recent group of phytohormones (Brassinosteroids) has been compiled by us. It is a class of over 40 polyhydroxylated sterol derivatives, ubiquitously distributed throughout the plant kingdom. A large portion of these steroids is restricted to the reproductive organs (pollens and immature seeds). Moreover, their strong growth-inducing capacity, recognized as early as prior to their identification in 1979, tempted the scientists to visualize the practical importance of this group of phytohormones. The brassin solution, from rape pollen, was used in a collaborative project by the scientists of Brazil and U. S. A. in a p- sowing seed treatment to augment the yield. This was followed by large-scale scientific programmes in U. S. , Japan, China, Germany and erstwhile U. S. S. R. , after the isolation of the brassinosteroids. This approach suits best in today’s context where plants are targeted only as producers and hormones are employed to get desired results. Chapter 1 of this book (which embodies a total of 10 chapters), gives a comprehensive survey of the hitherto known brassinosteroids, isolated from lower and higher plants.

Available in PDF, EPUB and Kindle. Book excerpt: The current growing interest of molecular biologists in plant hormone research is undoubtedly the most promising development of recent times. Many papers were presented during the 14th International Conference on Plant Growth Substances illustrating the impact of this new approach on our understanding of hormone-controlled processes. The specific character is the integrated study of plant growth regulation at all levels ranging from single molecules to the entire plant and its functioning in the environment. Hormones play an essential role in the regulation, but not an exclusive one. Other compounds and factors, such as Ca2+, for instance are often of equal relevance, because they may take part in the signal transduction pathway. Moreover, regulation of the regulator by non-hormonal factors is an essential part of any control mechanism. The present volume reflects the change in interest from plant growth substances to plant growth regulation.

Available in PDF, EPUB and Kindle. Book excerpt: Plant hormones play a crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate them to produce the form that we recognize as a plant. This book is a description of these natural chemicals: how they are synthesized and metabolized, how they act at both the organismal and molecular levels, how we measure them, a description of some of the roles they play in regulating plant growth and development, and the prospects for the genetic engineering of hormone levels or responses in crop plants. This is an updated revision of the third edition of the highly acclaimed text. Thirty-three chapters, including two totally new chapters plus four chapter updates, written by a group of fifty-five international experts, provide the latest information on Plant Hormones, particularly with reference to such new topics as signal transduction, brassinosteroids, responses to disease, and expansins. The book is not a conference proceedings but a selected collection of carefully integrated and illustrated reviews describing our knowledge of plant hormones and the experimental work that is the foundation of this information. The Revised 3rd Edition adds important information that has emerged since the original publication of the 3rd edition. This includes information on the receptors for auxin, gibberellin, abscisic acid and jasmonates, in addition to new chapters on strigolactones, the branching hormones, and florigen, the flowering hormone.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state of the skill of understanding brassinosteroids (BRs) signaling plus crosstalk with phytohormone and their association in plant adaptation to abiotic stresses comprising physiological, biochemical, and molecular developments. Due to progressively adverse environmental conditions and scarce natural resources, high-efficient crops have become more important than ever. For the successful improvement of stress-tolerant plants, it is vital to understand the precise signaling appliances that plants practice to abide stresses as well as how much these mechanisms are convinced by phytohormone. However, it is also debatable on which step plants can attain brassinosteroids (BRs) signaling from an evolutionary viewpoint. BRs are involved in modulating a large array of important functions throughout a plant’s life cycles. BRs are considered as one of the most important plant steroidal hormones that show a varied role in observing a wide range of developmental practices in plants. Our grip on brassinosteroids signaling has quickly extended over the past two decades, owing in part to the isolation of the constituents intricate in the signal transduction trail. The book proposes a useful guide for plant researchers and graduate students in connected areas.
