Xanthomonas

'... the final (eighth) chapter by Sutherland provides an invaluable source of information about the synthesis, structure, industrial usage and food applications of the xanthan polymer... very clear and informative... useful general summary tables of vectors and properties of avirulence genes are given... useful discussion... this is a very successful compilation of authoritative and up-to-date reviews, and the editors have achieved a good blend of complementing chapters. The book will be of considerable value for teaching and research... the text will not lose its usefulness quickly.' Trends in Microbiology '... an excellent overview of plant diseases caused by Xanthomonas, and gives an insight into the ecology and biology of this bacterium, as well as into genetic loci playing a role in the interaction with the plant...I believe that this very well-written book will be of great value to advanced students and to experts in both classical and molecular plant pathology, as well as to readers interested in plant-bacterium interactions.'
