Interesting Facts
In 2012, a group of Russian scientists from the Institute of Cell Biophysics of the Russian Academy of Sciences and the Institute of Physicochemical and Biological Problems of Soil Science of the Russian Academy of Sciences, led by David Abramovich Gilichinsky, managed to regenerate plants from placental tissue of seeds that are about 32 thousand years old [2] [3] [4] [5] [6] [7] . Seeds were found at a depth of 38 meters under a layer of permafrost in the Kolyma River region in the Magadan Region.
