A flower blooms after 30,000 years

Ice Age squirrel’s treasure chamber, a burrow containing fruit và seeds that had been stuck in the Siberian permafrost for more than 30,000 years. From the fruit tissues, a nhóm of Russian scientists managed béo resurrect an entire plant in a pioneering experiment that paves the way for the revival of other species .The Silene stenophylla is the oldest plant ever béo be regenerated, the researchers said, & it is fertile, producing White flowers và viable seeds .The experiment proves that permafrost serves as a natural depository for ancient life forms, said the Russian researchers, who published their findings in today’s issue of Proceedings of the National Academy of Sciences of the United States .“ We consider it essential Khủng continue permafrost studies in tìm kiếm of an ancient genetic pool, that of pre-existing life, which hypothetically has long since vanished from the earth’s surface, ” the scientists said in the article .Canadian researchers had earlier regenerated some significantly younger plants from seeds found in burrows .Svetlana Yashina of the Institute of Cell Biophysics of the Russian Academy Of Sciences, who led the regeneration effort, said the revived plant looked very similar lớn its modern phiên bản, which still grows in the same area in northeastern Siberia .“ It’s a very viable plant, & it adapts really well, ” she told The Associated Press in a telephone interview from the Russian town of Pushchino, where her lab is located .She voiced hope the nhóm could continue its work & regenerate more plant species .The Russian research nhóm recovered the fruit after investigating dozens of fossil burrows hidden in ice deposits on the right ngân hàng of the lower Kolyma River in northeastern Siberia, the sediments dating back 30,000 mập 32,000 years .The sediments were firmly cemented together và often totally filled with ice, making any water infiltration impossible — creating a natural freezing chamber fully isolated from the surface .“ The squirrels dug the frozen ground mập build their burrows, which are about the form size of a bóng đá ball, putting in xuất xắc first và then animal fur for a perfect storage chamber, ” said Stanislav Gubin, one of the authors of the study, who spent years rummaging through the area for squirrel burrows. “ It’s a natural cryobank. ”The burrows were located 125 feet below the present surface in layers containing bones of large mammals, such as mammoth, wooly rhinoceros, bison, horse & deer .Gubin said the study has demonstrated that tissue can survive ice conservation for tens of thousands of years, opening the way béo the possible resurrection of Ice Age mammals .“ If we are lucky, we can find some frozen squirrel tissue, ” Gubin told the AP. “ And this path could lead us all the way bự mammoth. ”Japanese scientists are already searching in the same area .
