Shoot tip cryotherapy for plant pathogen eradication

Abstract

Abstract Diseases caused by plant pathogens such as viruses, viroids and phytoplasmas cause huge economic losses of agricultural production and limit the safe movement of plant materials across borders. The use of pathogen‐free planting materials provides a strategy for efficient management of these diseases and facilitates the global exchange of genetic resources. Shoot tip cryotherapy is a novel biotechnology method that uses cryogenic procedures to eradicate plant pathogens from the diseased plants. Combining thermotherapy or chemotherapy with shoot tip cryotherapy has further enhanced pathogen eradication efficiency. This review provides updated and comprehensive information on shoot tip cryotherapy and the combination of thermotherapy or chemotherapy with shoot tip cryotherapy for pathogen eradication. Prospects are proposed for future studies.
