This month Genome Research published a study examining ancient whole genome duplication events in 41 different plant species. Using whole genome and transcriptome sequencing, the authors were able to determine that the plants had duplication events clustering with the Cretaceous-Paleogene mass extinction. This event, occurring roughly 66 million years ago, is associated with the loss of about 75% of the species on Earth, including dinosaurs. The authors propose that stress and extinction may have promoted the establishment of polyploid species, which contain more than two sets of chromosomes. The study is profiled on GenomeWebs The Daily Scan.
