Roles of novobiocin-sensitive topoisomerases in chloroplast DNA replication in Chlamydomonas reinhardtii.

M A Woelfle1, R J Thompson, G Mosig.   

Abstract

We have examined DNA replication in Chlamydomonas reinhardtii chloroplasts in vivo when chloroplast type II topoisomerases are inactivated with sublethal doses of novobiocin. DNA replication is at first inhibited under these conditions. However, after a delay of several hours, chloroplast chromosomes initiate a novobiocin-insensitive mode of DNA replication. This replication starts preferentially near a hotspot of recombination in the large inverted repeats, instead of from the normal chloroplast origins, oriA and oriB. It replicates one, but not the other single-copy region of the chloroplast chromosome. We speculate that novobiocin-insensitive DNA replication in chloroplasts requires recombination in this preferred initiation region.
