Oldest Root Stem Cells From the Carboniferous

Scientists at Oxford University have discovered the oldest known population of plant root stem cells in a 320 million-year-old fossil.

The cells, which gave rise to the roots of an ancient plant, were found in a fossilised root tip held in the Oxford University Herbaria.

As well as revealing the oldest plant root stem cells identified to date, the research also marks the first time an actively growing fossilised root has been discovered - in effect, an ancient plant frozen in time.

The study is published in the journal Current Biology.
