Yeast Sir2 protein regulates chromatin structure and suppresses recombination at the multiple tandem rDNA array. In the current issue of Cell, Kobayashi and colleagues reinvestigate rDNA dynamics in sir2 strains and find that Sir2 is necessary to recruit cohesins to the array, which influences the nature of rDNA recombination events.
