Summary:

This authoritative book contains fifteen chapters whose breadth reflects the diversity of this research area. Topics covered range from: understanding the mechanisms of virus resistance in plants, and the management of whitefly-transmitted viruses, to the principles and methods involved in genetic engineering of virus resistant plants. Other chapters cover individual crops such as papaya, cassava, rice, tomato, and banana, for which virus resistance has been accomplished by employing different transgenic technologies. This volume is essential reading for everyone working in this field, both students and specialists, from academia, research institutes/organizations and industries.
