S. coelicolor YSK3654 R5- medium time course study. Streptomyces coelicolor

Antibiotic biosynthesis in Streptomyces species is controlled by a complex genetic and biochemical network of global and pathway specific regulators. Details of their precise interactions in mediating temporal and spatial expression of secondary metabolite genes remain poorly defined. In this study, we employed whole-genome microarrays to investigate the temporal transcriptome profiles of S. coelicolor A3(2) deltaSCO3654::apr mutant strain (YSK3654) and compare it to the wild-type M145 strain. SCO3654 is a putative two-component system sensor kinase. Overall design: The time-course study involved analysis of 9 samples (10h, 13h, 16h, 19h, 22h, 25h, 31h, 35h, 37h). All samples were analyzed on duplicate arrays (2 technical replicates). Genomic DNA of S. coelicolor wild type (M145) was used as a reference for all the arrays. cDNA was labeled with Alexa647 and genomic DNA was labeled with Cy3.
