Longevity of cryogenically stored seeds.
Though cryogenic storage is presumed to provide nearly infinite longevity to cells, the actual shelf life achieved under ultra-cold temperatures has not been addressed theoretically or empirically. Here, we report measurable changes in germination of dried seeds stored under liquid nitrogen conditions for >10 years. There was considerable variability in the extent of deterioration among species...

Global food security is hampered by the fact that today’s high-yield grains are hybrids, with seeds that fail to retain all of the desired traits, necessitating ongoing rounds of breeding and selection.
