This Week in PNAS

An international team led by investigators in France outlines efforts to sequence and characterize the genome of the red algal species Chondrus crispus, commonly called Irish moss — a member of a lineage descended from the first photosynthetic eukaryotes formed through endosymbiosis. After using Sanger sequencing to tackle a C. crispus sample grown from material collected in Peggy's Cove, Nova Scotia, in the 1980s, the researchers delved into the 105 million-base-pair genome sequence, identifying 9,600 or so predicted protein-coding genes.
