Transcriptomic analysis of a putative LysR family regulator, a putative Dps, and a cystine importer disrupted mutants in radiation resistant bacterium Deinococcus geothermalis

Here, we compared gene expression level by RNA-Seq analysis among a wild-type (WT) Deinococcus geothermalis strain, a dgeo_2840 of LysR family member gene (Δdgeo_2840), a putative Dps dgeo_0257 (Δdgeo_0257), and a cystine importer dgeo_1986-1987 gene disrupted strain (Δdgeo_1986-1987). From this transcriptomic data, we detected dgeo_2840, dgeo_0257, and dgeo_1986-1987 controlling genes which were somehow up-regulated and/or down-regulated. In particular, Deinococcus geothermalis has a total of 73 insertion sequences (ISs) in genomes, and some of them are actively transposed to other loci with replicative mode by the oxidative stress of hydrogen peroxide treatment. 4 samples including WT and 3 mutant strains.
