In most organisms, meiotic recombination begins with programmed DNA double strand break (DSB) formation by Spo11. Here, we present evidence that Tel1/Mec1, the budding yeast ATM/ATR, regulate DSB formation by phosphorylating Rec114, an essential Spo11-accessory protein. Analyses of a non-phosphor...
