The budding yeast genome encodes two Pif1 family helicases, Pif1 and Rrm3, previously shown to have distinct functions in the maintenance of telomeres and other aspects of genome stability. Here the authors identify a role for Pif1 (and Rrm3) in promoting DNA replication and suppressing R-loop mediated DNA damage at tRNA genes.
