Summary

The temperature sensitivity of sporulation in a well-characterized yeast strain lacking any known temperature sensitive genes has been investigated. Cytological observations by electron microscopy demonstrate that cells incubated in sporulation medium at a temperature inhibitory to sporulation became arrested in meiotic prophase. The stage of arrest was identified as pachytene by the presence of duplicated (but unseparated) spindle pole bodies and synaptonemal complex. Transfer of the arrested culture to lower temperature permitted resumption of meiosis and sporulation; transfer to vegetative medium resulted in reversion to mitotic division. Genetic analysis of cells that had reverted to mitosis revealed that commitment to intragenic recombination had occurred by the time of arrest. Prolonged incubation at the elevated temperature resulted in the enhancement of intragenic recombination above normal levels, suggesting that some aspect of recombination continued to occur during the pachytene arrest. Evidence is presented that DNA replication, although depressed overall in the arrested cultures, had occurred to completion in many arrested cells.
