Abstract
It is well documented that the formation of the DNA double-strand breaks (DSBs) that initiate meiotic recombination is influenced by chromatin and larger scale chromosome organization, but the molecular nature of this influence has remained elusive. Several recent studies, including (this issue of Cell), shed light on this issue by revealing roles for posttranslational histone modifications in promoting DSB formation.
