| Sumario: | A temperature upshift of ten or more degrees in the growth temperature of an
Escherichia coli culture causes induction of on extra rounds of chromosome replication
that are denominated HIR (heat induced replication). In this work we have determined
the estructural requirements in DNA and the functions that are needed during the
initiation and elongation in HIR. The model that we proposed explains the nature of this
replication. Consedering the fact that heat induced replications were also identified in
minicromosomes and plasmids, HIR could be a general response to heat stress in the
bacterial world. |
