Project description:Two component sensor-response regulator systems (TCSs) are very common in the genomes of the Streptomyces species that have been fully sequenced to date. It has been suggested that this large number is an evolutionary response to the variable environment that Streptomyces encounter in soil. Notwithstanding this, TCSs are also more common in the sequenced genomes of other Actinomycetales when these are compared to the genomes of most other eubacteria. In this study, we have used DNA/DNA genome microarray analysis to compare fourteen Streptomyces species and one closely related genus to Streptomyces coelicolor in order to identify a core group of such systems. This core group is compared to the syntenous and non-syntenous TCSs present in the genome sequences of other Actinomycetales in order to separate the systems into those present in Actinomycetales in general, the Streptomyces specific systems and the species specific systems. Horizontal transfer does not seem to play a very important role in the evolution of the TCS complement analyzed in this study. However, cognate pairs do not necessarily seem to evolve at the same pace, which may indicate the evolutionary responses to environmental variation may be reflected differently in sequence changes within the two components of the TCSs. The overall analysis allowed subclassification of the orphan TCSs and the TCS cognate pairs and identification of possible targets for further study using gene knockouts, gene overexpression, reporter genes and yeast two hybrid analysis.

Project description:BldB is a regulatory protein in Streptomyces and most species have a number of paralogs in their genomes. Deletion of BldB leads to a developmental deficiency and the colonies fail to produce aerial mycelium. In this experiment global gene expression was compared between the WT and BldB deletion strain of Streptomyces venezuelae NRRL B65442 after 10, 14 and 22 hours of growth in liquid cultures.

Project description:Genes encoding dodecin proteins are present in almost 20% of archaeal and in more than 50% of bacterial genomes. Archaeal dodecins bind riboflavin (vitamin B2), are thought to play a role in flavin homeostasis and possibly also help to protect cells from radical or oxygenic stress. Bacterial dodecins were found to bind riboflavin-5’-phosphate (also called flavin mononucleotide or FMN) and coenzyme A, but their physiological function remained unknown. In this study, we set out to investigate the relevance of dodecins for flavin metabolism and oxidative stress management in the phylogenetically related bacteria Streptomyces coelicolor and Streptomyces davawensis. Therfore we have treated Streptomyces coelicolor wildtype, Streptomyces davawensis wildytype and Streptomyces davawensis dodecin deletion strain with plumbagin, a compound, which induces oxidative stress in exponential and stationary growth phase and analysed the transcriptome via RNA-seq (Illumina TruSeq stranded mRNA libraries sequenced on Illumina HiSeq rapid mode 2 x 70nt PE).
