'this book brings together a vast array of up-to-date, relevant information of immense value to research workers in many areas of plant pathology ... I congratulate the editors on producing a book which I think will overcome our natural defence mechanisms against yet another molecular text. Most of us involved in plant pathology research will benefit from having a copy of this book on our shelf.'Peter Mills, Belfast, Society for General Microbiology Quarterly, November 1992
