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.
