Previous work identified the winged helix-turn-helix DNA binding transcription factor (TF) RosR (encoded by VNG0258H gene), which dynamically regulates expression of more than 300 genes in response to oxidative stress in Halobacterium salinarum (Sharma 2012). RosR is required for survival of oxidant...

Analysis of topoisomerase function in bacterial replication fork movement: use of DNA microarrays. We used DNA microarrays of the Escherichia coli genome to trace the progression of chromosomal replication forks in synchronized cells. We found that both DNA gyrase and topoisomerase IV (topo IV) prom...

Secondary metabolites are involved in the plant stress response. Among these are scopolin and its active form scopoletin, which are coumarin derivatives associated with reactive oxygen species scavenging and pathogen defence. Here we show that in Arabidopsis thaliana, scopolin accumulation can be in...
