In Caenorhabditis elegans, germline apoptosis is promoted by egl-1 and ced-13 in response to meiotic checkpoint activation. We report that the requirement for these two factors depends on which checkpoints are active. We also identify a regulatory region of egl-1 required to inhibit germline apoptosis in response to DNA damage incurred during meiotic recombination.
