- Russians regenerate seed frozen for over 30.000 years
 
Silene stenophylla is the oldest plant ever to be completely regenerated. It is fertile, produces white flowers and viable seeds. An entire plant was grown from seed found in a fruit stuck in burrows made by squirrels in the Siberian permafrost about 31.800 years ago (plus/minus 300 years). The burrows were located 40m below the present surface. The regenerated plant looks very similar to its modern counterpart species which still grows in the same area of Northeast Siberia. Soil sediments were cemented together and filled with ice creating a natural freezing chamber fully isolated from the surface.
