The co-evaluation of plants and microbes has led to an elaborate system of genes involved in recognitions, attack and defence. This volume explores the genes and the regulation of their expression. Topics covered range from considerations of population genetics to the identification of defence-related genes and their regulation. The book provides a concise review of the latest developments in this rapidly developing field of agronomic importance.
