Transcriptome sequencing was carried out on an Illumina HiSeq platform to investigate CRISPR-Cas and DNA repair systems by Csa3b in Sulfolobus islandicus Rey15A. We compared the differently expressed genes in Sulfolobus islandicus Rey15A strain with csa3a overexpression vs. Sulfolobus islandicus Rey15A strain carrying an empty expression vector,We find thatcmr-α (SiRe_0890 ~ SiRe_0895) and cmr-β (SiRe_0597 ~ SiRe_0603)ãthe DNA double strand break (DSB)repair genes, including nurA, rad50, mre11, and herA (SiRe_0061 ~ SiRe_0064), as well as two subunits of DNA polymerase II (SiRe_0615 and SiRe_0617) that function in DNA repair, were significantly up-regulated. Our data indicated that the Csa3b regulator couples transcriptional activation of cmr genes, DNA repair genes.
