Breaking News English .com, Scientists Regrow 30,000-Year-Old Plant (22nd February, 2012)

Russian scientists have recreated a plant from cell tissue that had been frozen for 30,000 years. The research team from Russia's Institute of Cell Biophysics team regenerated the plant from tissue found in the Siberian permafrost. It was a pioneering project that paves the way for other plant species to be revived. The plant the scientists brought back to life is called the Silene stenophylla. It is the oldest plant ever to be regenerated, beating the previous record for date palm seeds that were stored for 2,000 years in Israel. The plant had been stored away by squirrels during their hibernation 30 millennia ago, during the age of woolly mammoths. It froze and never thawed.

The scientists believe that the regeneration of the Silene stenophylla plant means the permafrost is a natural store of ancient life forms, many of which could be recreated. Lead researcher Svetlana Yashina said: “We consider it essential to continue permafrost studies in search of an ancient genetic pool, that of pre-existing life, which hypothetically has long since vanished from the earth's surface.” Dr Robin Probert, head of conservation and technology at the UK's Millennium Seed Bank, said: “There is an opportunity to resurrect flowering plants that have gone extinct in the same way that we talk about bringing mammoths back to life, the Jurassic Park kind of idea.”
