32,000-Year-Old Plant Brought Back to Life—Oldest Yet
by Rachel Kaufman
The oldest plant ever to be regenerated has been grown from 32,000-year-old seeds—beating the previous recordholder by some 30,000 years.
A Russian team discovered a seed cache of Silene stenophylla, a flowering plant native to Siberia, that had been buried by an Ice Age squirrel near the banks of the Kolyma River (map). Radiocarbon dating confirmed that the seeds were 32,000 years old.
The mature and immature seeds, which had been entirely encased in ice, were unearthed from 124 ft (38 m) below the permafrost, surrounded by layers that included mammoth, bison, and woolly rhinoceros bones. The mature seeds had been damaged—perhaps by the squirrel itself, to prevent them from germinating in the burrow. But some of the immature seeds retained viable plant material…
