This Week in PLOS

In PLOS Genetics, researchers from the University of Kentucky and the Salk Institute explore the mechanisms of programmed genome rearrangements that occur in the sea lamprey, Petromyzon marinus, during development. The team used labeled immunofluorescent antibodies to follow methylation and histone marks during sea lamprey development, which involves the loss of some 20 percent of the sea lamprey genome from somatic cell lineages.
