The spindle assembly checkpoint (SAC) monitors defects in kinetochore-microtubule attachment or lack of tension at kinetochores and arrests cells at prometaphase. In fission yeast, the double mutant between pot1Δ and the helicase-dead point mutant of the RecQ helicase Rqh1 gene (rqh1-hd) accumulates Rad51-dependent recombination intermediates at telomeres and enters mitosis with those intermediates. Here, we found that SAC-dependent prometaphase arrest occurred more frequently in pot1Δ rqh1-hd double mutants than in rqh1-hd single mutants. SAC-dependent prometaphase arrest also occurred more frequently in rqh1-hd single mutants after cells were released from DNA replication block compared to the rqh1-hd single mutant in the absence of exogenous insult to the DNA. In both cases, Mad2 foci persisted longer than usual at kinetochores, suggesting a defect in kinetochore-microtubule attachment. In pot1Δ rqh1-hd double mutants and rqh1-hd single mutants released from DNA replication block, SAC-dependent prometaphase arrest was suppressed by the removal of the recombination or replication intermediates. Our results indicate that the accumulation of recombination or replication intermediates induces SAC-dependent prometaphase arrest, possibly by affecting kinetochore-microtubule attachment.
