Sphagnum peat moss made the news over at BBC Earth News last week. The title of the paper tells it all "One haploid parent contributes 100% of the gene pool for a widespread species in northwest North America". I could go on to try and give my own take on this research, but I think that the BBC article does a good job of hitting the highlights. All the other mentions of this research seem to point back to this BBC article. Way to go BBC mentioning some cutting edge bryo-research!
Here is a link to the abstract for the journal article. To access the full publication you may need to have a subscription through your library.
Thanks to my pal Kathryn for forwarding me this article!
