Project description:The purpose of the study is to identify Irr-responsive genes in the bacterium Bradyrhizobium japonicum. Parent strain LO was compared to irr mutant strain LODTM5 by whole genome microarray analysis. Both cell types were grown in iron-limited media. Keywords: Comparison of B. japonicum wild type and mutant cells
Project description:The purpose of the study is to identify iron-responsive genes in the bacterium Bradyrhizobium japonicum. Parent strain LO was grown under iron limitation or under iron sufficiency and compared to each other by whole genome microarray analysis. Keywords: Comparison of cells grown under low or high iron conditons
Project description:The alphaproteobacterium Paracoccus denitrificans Pd1222 has two different, yet functionally redundant acetyl-CoA assimilation routes: the Ethylmalonyl-CoA pathway (EMCP) and the glyoxylate cycle (GC). The EMPC and the GC each tightly control the balance between catabolism and anabolism by shifting flux away from the oxidation of acetyl-CoA in the tricarboxylic acid (TCA) cycle towards biomass formation. RamB (encoded by Pden_1365), a member of the ScfR family, is a transcriptional regulator in P. denitrificans Pd1222 that controls expression of GC. To analyze the role of RamB in the coordinated regulation of metabolic plasticity, we analyzed the global transcriptome of P. denitrificans Pd1222, as well as the ramB-deletion strain during mid-exponential growth phase on defined minimal medium with acetate or succinate as carbon sources.
