Presented book is an excellent overview of black rot diseases of Crucifiers that caused by Xanthomonas, and it gives an insight into the ecology and biology of this bacterium, as well as into detailed biochemical profile and shown a easiest way to identify the Xanthomonas by phenotypes. I believe that this very well-written book will be of great value to advanced students and to experts in both classical, biochemical and molecular plant pathology, as well as to readers interested in plant-bacterium interactions.

Microbes make up most of the biodiversity on Earth, and several of the processes which microorganisms perform are of critical importance for decomposing organic matter and recycling plant materials. They are important for biological cycling of nutrients, maintenance of soil fertility and in crop protection and enzyme technoloogy. Therefore, knowledge of the phenotypic, genotypic and biological characters to identify a microorganism is essential for developing ecosystem services and to frame strategies for their efficient utilization in agriculture and allied sectors. However Traditional...
