One plant to rule them all

Across northwestern North America, every example of a common peat moss called Sphagnum subnitens is genetically identical, researchers have discovered.

That means every specimen can be traced back to a single parent, which likely conquered North America in less than 300 years, and shows how a single ‘general purpose’ genome can allow a plant to grow in a range of climates. more
