Produktbeschreibung

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.

Rezensionen

From the reviews:

"It deals with the chemistry, with perception and signal transduction, with physiological effects and with use in agriculture. ... as this book summarizes a large part of the vast amount of knowledge on brassinosteroids, it is highly relevant for researchers interested in this new plant growth regulator." (Geert-Jan de Klerk, Plant Cell, Tissue and Organ Culture, Vol. 79, 2004)

"In this book, the editors focus on the practical importance of brassinosteroids in agricultural and horticultural applications ... . the book might be interesting to scientists and students working in fundamental and applied research since it provides a comprehensive overview of the practical feasibility of brassinosteroid application, which is not readily accessible elsewhere." (Bernd Schneider, Journal of Plant Physiology, Vol. 161 (11), 2004)
