Caption for April 2005 Agricultural Research magazine article, "Finding New Ways To Protect and Preserve Plant Genetic Resources." Technician Remi Bonnart (foreground) flash-freezes plant shoot tips while plant physiologist Christina Walters places cryopreserved materials into cryovats for long-term storage. Droplets of cryoprotecting solution hold shoot tips onto foil strips. The strips are plunged into liquid nitrogen slush that is formed by placing liquid nitrogen in a vacuum.
