It takes the student on a tour from basic plant biology and genetics to breeding and principles and applications of plant biotechnology. Toward the end of the book, we diverge from science to perceptions and patents, which are arguably as important as the science in delivering agricultural biotechnology products to people who need them. I asked some of the leading scientists in the field, many of whom teach in biotechnology, to write chapters of this textbook. I think that seeing several points of view is more interesting to the reader than if I’d written the entire text myself (at least it is more interesting to me).
