'The book is an excellent overview of the many kinds of singalling processes in plants. It is of high interest to established plant scientists and also to graduate students, and will stimulate new research to further reveal the remaining secrets in the signalling pathways of plants. The book can be recommended to all plant biologists and should be present in the book shelves of general libraries and plant biology institutions. Many plant physiologists will find it useful to possess a personal copy.' Journal of Plant Physiology, 147 (1995) '...this book is very worthwile reading in order to keep up with new developments in the field of plant physiology and to translate it to applicable knowledge in horticulture and agriculture.' Scientia Horticulturae, 68 (1997)
