title: Antisense RNAs in plasmids: control of replication and maintenance.
abstract: The search for small RNAs which might act as riboregulators became successful over the past two years both in prokaryotes and in eukaryotes. Moreover, artificially designed antisense RNAs have become powerful tools to downregulate the expression of targeted genes. It seems that antisense RNAs as regulatory molecules are most likely to be found everywhere. However, the first naturally occuring antisense RNAs were identified in plasmids and other prokaryotic accessory DNA elements. The thorough and detailed analyses of these systems have provided deep insights into structure and function of prokaryotic antisense RNAs and the kinetics of antisense/sense RNA interaction. Here, I focus on the role of antisense RNAs in plasmid replication and maintenance.
