Project description:Response of Cupriavidus metallidurans CH34, AE104 and delta zupT mutant to Zn/EDTA stress In this study 3 different treatments were performed to acquire expression profiles of the total genome of Cupriavidus metallidurans
Project description:Cupriavidus metallidurans CH34 is a metal resistant beta-proteobacterium. The genome of this bacterium contain many genes involved in heavy metal resistance. Gene expression of C. metallidurans was studied after the addition of of Zn(II), Cd(II), Cu(II), Ni(II), Pb(II), Hg(II) or Co(II). Keywords: Heavy metal stress response

Gene expression of C. metallidurans was studied after the addition of of Zn(II), Cd(II), Cu(II), Ni(II), Pb(II), Hg(II) or Co(II). Keywords: Heavy metal stress response Cultures of C. metallidurans CH34 were grown at 30°C until OD reached 0.6 (mid- exponential phase cultures). Heavy metals (0.8 mM of Zn(II), 0.5 mM of Cd(II), 0.1 mM of Cu(II), 0.6 mM of Ni(II), 0.4 mM of Pb(II), 5 uM of Hg(II) and 0.5 mM of Co(II)) were added to the culture for 30 minutes induction time. Total RNA was extracted, reverse-transcribed and labeled with Cy3-dCTP for the control (without metal) and with Cy5-dCTP for each conditions (challenged with one metal). Labeled cDNA were (control and one condition) added to a spotted slide for overnight hybridization at 42°C. Slides were scanned with a laser at 532 and 635 nm.
