Abstract:

Natural plasmids inhabiting some species of Lactobacillus carry many important genes with biological
functions and resistance to stress factors, and are significant for genetic, metabolic and evolutional studies of
Lactobacillus. In this review, biological properties, distribution and functions of natural plasmids from Lactobacillus
are summarized. The recent progress in research on replication types and regulatory mechanisms of plasmids from
Lactobacillus is discussed, and future research directions are also proposed. We hope that this paper can provide useful
information and references for relevant researchers.

Key words: Lactobacillus, plasmid, replication, regulation, antisense RNA
