Plant Diseases are reasonably uniform in size and stability. They generally sediment between 50 and 500S and are resistant to chelating agents. Few host components share these sedimentation and stability properties. Viruses can, therefore, be easily purified by ultra centrifugation. Subsequent gel electrophoresis of Capsid proteins followed by silver staining detects and partially characterizes viruses. Capsid protein size and yield often permit assignment of unknown viruses to a narrow range of taxa. The unrivaled practical handbook for the identification, treatment and prevention of plant problems. Guidance from the experts in the Identification, treatment and prevention of plant pests, diseases and disorders.
