When genebanks must cryopreserve a diverse range of clonally propagated plants, it is often most effective to preserve their shoot tips–tiny growing points in their tissues. USDA’s Remi Bonnart discusses the circumstances for which shoot tip cryopreservation is appropriate, and shows how a variety of shoot tips preservation methods are used to preserve grape, strawberry, […]
Cryopreservation is a technology that allows genebanks to preserve plant genetic resources on a long-term basis. USDA’s Jennifer Kendall discusses how cryopreservation is used at the National Laboratory for Genetic Resources Preservation to preserve clonal material–that is tissue that contains the exact same genetic makeup as the source plant–in liquid nitrogen. This video was made […]
