Description
Summary:Grapevine (<i>Vitis</i> spp.) is one of the most economically important temperate fruit crops. Grapevine breeding programs require access to high-quality <i>Vitis</i> cultivars and wild species, which may be maintained within genebanks. Shoot tip cryopreservation is a valuable technique for the safe, long-term conservation of <i>Vitis</i> genetic resources that complements traditional field and in vitro germplasm collections. <i>Vitis</i> is highly susceptible to virus infections. Virus-free plants are required as propagation material for clonally propagated germplasm, and also for the global exchange of grapevine genetic resources. Shoot tip cryotherapy, a method based on cryopreservation, has proven to be effective in eradicating viruses from infected plants, including grapevine. This comprehensive review outlines/documents the advances in <i>Vitis</i> shoot tip cryopreservation and cryotherapy that have resulted in healthy plants with high regrowth levels across diverse <i>Vitis</i> species.
