About this book

This book presents the specific collaborations and the defensive and counter-defensive interactions that govern the virus intracellular cycle an plant infection. It describes the relations between the virus an the agro-environment and presents recent developments in diagnosis and control methods. It also gives detailed information on plant virus evolution and taxonomy.

. Concluding remarks

The defence reaction of the infected plant
