Abstract

Summary: A 5-bromo-2′-deoxyuridine (BUdR)-tolerant derivative of a thymidine (TdR)-requiring strain of was used to examine the effect of BUdR, an analogue of TdR, on sporulation. At a TdR: BUdR ratio which had little effect on growth, sporulation was inhibited if cells were exposed to BUdR during the period of DNA synthesis at the onset of the process. Cells recovered from BUdR inhibition of sporulation if the analogue was removed and DNA replication allowed to continue with TdR alone. BUdR prolonged the period of DNA synthesis during sporulation and experiments with chloramphenicol suggested that this was due in part to unscheduled initiation of new rounds of replication.
