The group of Russian scientists from the Institute of Physical and Biological Problems in Soil Science in Pushchino been thawed and germinate seeds of the plant, which is more than thirty thousand years lay under 38 feet of permafrost.
Frozen plant and animal remains — is the most interesting material for research, provides the most complete information about the life on the planet in the past era. The body parts of ancient animals, pieces of plants can learn a lot more than any of the fossils, and surviving fragments of DNA they give hope for the resurrection of ancient fauna and flora.
Along the banks of the Kolyma River in the Magadan region has many deposits of frozen plants that grow here are about 40-25 thousand years ago. Previously, scientists often find pieces of seeds, but due to internal injuries, none of them have so far been able to recover.
A group of Russian biologists exploring the many sediment samples found in the Magadan region immature seeds campion in almost perfect condition — "nest egg" of ancient rodents, which was made of about thirty thousand years ago. Able to determine the age of the seeds by radiocarbon analysis. This land has long been constrained by the permafrost, and all the while narrow-leaved campion seeds, plants resistant to low temperatures, lay in a natural refrigerator, which allowed them to survive, writes "BBC News".
Most viable seed biologists fragments placed in a nutrient medium, which simulates the growing plant. After a while, these fragments become a full-shoots that were transplanted into the soil. Crossed them with the modern family, and each other, biologists have tried to get viable seeds.
According to the researchers, the ancient and modern plants did not differ either in color or in form, only inflorescences were others. Compared with fossil campion flowers, the petals of modern plants are cut wider and stronger. In addition, in the colors of the modern shrub has pistils and stamens, whereas their predecessors had male and female inflorescences.
In both cases, the scientists were able to get healthy seeds that have become full-fledged adult plants. This is the first case of successful resuscitation of flowering plants, the seeds of which tens of thousands of years are under a layer of permafrost. According to Russian biologists seeds managed to survive thanks to sucrose contained in the cells of the surrounding tissue. Such research can help not only to revive extinct species, but also allow to study the climatic changes that have occurred in the world, according to RIA Novosti.
