We have studied the repair of a DNA-DSB created by the VMA1-derived endonuclease in mutants that have different levels of Spo11-DSBs: WT (sae2), few (hop1), and none (spo11-Y135F). In spo11-Y135F and hop1 cells, intrachromosomal repair is more frequent than in WT and sae2 cells. In spo11-Y135F cells there was no chromosome pairing or synapsis and a faster turnover of resected DNA. Compared to WT and sae2 cells, spo11-Y135F and hop1 cells have a greater proportion of long resection tracts. The data suggest that high levels of Spo11-DSBs are required for normal regulation of resection, even at a DSB created by another protein. WT control over resection could be important for directing repair to be interchromosomal, increasing the chance of creating interhomolog connections essential to meiotic segregation.
