Russian scientists have grown a plant from the seed of the Pleistocene 30,000 years ago

 

In Yakutia, near the Kolyma River in northeastern Siberia, the permafrost has become a place seed saving 30,000 years ago.

Chukchi copies of American gophers long ago buried in the mud of the ancient seeds of dark fruit plants. Mining rodent quickly froze in the cold ground, and perfectly preserved in permafrost, waiting for the meeting with our investigators. After 30 000 years the seeds have finally been excavated. Russian scientists have restored the plant Pleistocene and grew older plants in the laboratory. A year later, the plant grew and bore fruit.

This copy is distinctly different from modern Silene stenophylla (plants of the family Caryophyllaceae). The positive results of studies provide start searching for new sources of ancient gene pools, which are believed to have been lost in history.

Fruit with seeds were buried at a depth of about 40 meters in the permafrost at a constant temperature of -7 C. Radiocarbon dating showed that the Fruit was 31,800 years, plus or minus 300 years. The seeds are packed in a protective box, retain the embryo of the new plant will come until favorable conditions for its growth.

A group of scientists headed by David Gilichinsky of Sciences conducted the study with three seeds of the fruit. They podzhivili tissue culture cocktail of nutrients that cause the growth of the root. Once the seedlings have germinated, transplant them into pots in the greenhouse. As expected, the seedlings have grown, developed and gave fruit seeds. Compared to its modern sibling, campion angustifolia, an ancient plant twice as many seeds, but the modern version of the roots grow twice as fast.

Mirnt.ru was also aware that to guarantee you receive the seeds of ancient plants, the team made the artificial pollination of flowers, and conducted additional experiments on the germination of seeds. The results were quite interesting. The ancient plant survivability is much higher than that of modern counterparts. In the restored ancient plants was recorded a 100 percent germination rate, while that of modern plants it has not exceeded 86 percent. The researchers suggest that the time and the ice does not have a decisive role in the bloom of plants, there is still some factors, such as radioactive cycles of our planet. Over 30,000 years to seed impacted quite a large amount of gamma radiation. Scientists estimate that the fruit received a dose of 0.07 kGy of gamma radiation, and as they say, is the maximum dose, after which the tissue can remain viable.

This experiment is interesting not only because it managed to recreate a plant that 30,000 years, it also confirms the fact that the permafrost may be an important place of gathering extinct plant gene pool. As we already know, a lot of old ground squirrel burrows were found in Alaska. This study also provides an opportunity to claim that global warming could lead to the melting of permafrost in areas, freeing up a lot of frozen plants and simple organisms. Scientists say that a lot of ancient organisms can come out of cold sleep, and these forms can become part of modern ecosystems, affecting phenotypes of modern and changing landscapes.
