New genome size estimates for liverworts.

Genome size, or nuclear DNA content, has been found to vary greatly among living organisms. In land plants, estimates have been obtained for most major plant groups, but there are very few estimates for liverworts. Here we present several new genome size estimates for liverworts. To estimate genome size, liverworts were analyzed from both cultured and wild populations. Nuclei was isolated from the gametophyte tissue and stained with propidium iodide, and then analyzed for DNA content using flow cytometry. There was a wide range in the genome size estimates for the liverworts, ranging from less than 0.3pg to greater than 10.0pg. The new estimates obtained contribute greatly to our knowledge of early land plant genome size evolution.
