摘要

Genome sequencing was performed by the PacBio RS II platform and Illumina HiSeq 4000 platform to discover the metabolic profile of the Deinococcus wulumuqiensis R12, which was isolated from radiation-contaminated soils in Xinjiang Uygur Autonomous Region of northwest China. The genome of 3.5 Mbp comprises one circular chromosome and four circular plasmids with 3679 genes and a GC content of 66.97%. A total of 41 new transcriptional factors were identified using the DeepTFactor tool. Genomic analysis revealed the presence of genes for homologous recombination repair, which suggested high recombination efficiency in R12. Three Type I and one Type II RM systems, two CRISPR arrays, and one Cas-Type IC protein were found, allowing the development of endogenous CRISPR-Cas gene-editing tools. Additionally, we found that R12 has a broad spectrum of substrate utilization, which was validated by physiological experiments. Genes involved in the carotenoid biosynthesis pathway and the antioxidative system were also identified. Overall, the comprehensive description of the genome of R12 will facilitate the additional exploitation of this strain as a versatile cell factory for biotechnological applications.
