The BACILLUS SUBTILIS Genome: Replication-Order and Map-Position Discrepancies—evidence for a Second Origin

PMCID: PMC1213236  PMID: 4218179

Abstract

Replication order to map position discrepancies have been documented in B. subtilis. The discrepancies were found to occur whenever the genome of B. subtilis was replicated under a variety of physiological conditions and in both 168 and W23 strains. The earliest replicating marker involved in these discrepancies was thr versus purB and aroA versus recA. A detailed linkage analysis of the ura to argA region was consistent with its being a continuous linkage group. This led to the conclusion that an origin for new starts at replication exists between recA and aroA.
