Tulip tree‘s genome is ‘molecular fossil’

By Mark Kinver, Environment reporter, BBC News

The “extraordinary level of conservation” of genetic data in the tulip tree remains largely unchanged since the dinosaurs, a study suggests.

The species’ genomic change is about 2,000 times slower than in humans, making it a “molecular fossil”, a team of US researchers said.

The new information has affected our understanding of flowering plants‘ evolution, they added.

The findings have been published in the open access journal BMC Biology.

The team from the universities of Indiana and Arkansas sequenced the mitochondrial genome of the species (Liriodendron tulipifera), only to discover it had one of the slowest silent mutation rates (a process that does not affect gene function).

They added that the sequencing showed…
