High-throughput DNA sequencing of ancient timbers: a new method to explore the evolution of forests

From recreational use to timber production, and not forgetting numerous other ecosystem services, forests are faced with many challenges, notably in a context of global change. To open new perspectives that will provide a clearer understanding of the evolution of forest populations and predict their future in the context of climate change, an international scientific team involving researchers from INRA and CNRS has successfully isolated and sequenced the DNA of oak in the remains of ancient pieces of timber – some dating from nearly 10,000 years.
