Technical Abstract: Plant obligate pathogens such as viruses, viroids and phytoplasma have been a constraint for sustainable development of agricultural production. The production of pathogen-free planting materials provides a strategy for efficient management of these diseases and facilitates the global exchange of plant genetic resources. Shoot tip cryotherapy, a novel biotechnology method, has been demonstrated to efficiently eradicate plant obligate pathogens from the diseased plants. Combining thermotherapy or chemotherapy with shoot tip cryotherapy has further enhanced pathogen eradication efficiency. Assessments of genetic stability and field performance of cryo-derived plants support the use of the pathogen-free plants to promote agricultural production. This review provides updated and comprehensive information on advances in shoot tip cryotherapy for eradication of plant obligate pathogen in the past 25 years.
