Complete genome sequence of the Radiation-Resistant bacterium Rubrobacter radiotolerans RSPS-4

Area of Science:

• Microbiology
• Genomics
• Extremophile research

Background:

• Rubrobacter radiotolerans is an extremophilic bacterium known for its high resistance to radiation.
• Strain RSPS-4 was isolated from a hot spring environment in Portugal.
• Understanding the genetic basis of radiation resistance is crucial for various applications.

Purpose of the Study:

• To present the complete genome sequence of Rubrobacter radiotolerans strain RSPS-4.
• To assemble and annotate the genome.
• To compare the RSPS-4 genome with the type strain of R. radiotolerans.

Main Methods:

• Whole-genome sequencing of strain RSPS-4.
• Bioinformatic assembly and annotation of the obtained sequence data.
• Comparative genomic analysis with the type strain.

Main Results:

• The complete genome of strain RSPS-4 consists of a single circular chromosome (2,875,491 bp) and three circular plasmids.
• The G+C content of the chromosome is 66.91%.
• The genome harbors 3,214 predicted protein-coding genes, 46 tRNA genes, and one rRNA operon.

Conclusions:

• The genome sequence of Rubrobacter radiotolerans strain RSPS-4 provides a valuable resource for studying radiation resistance.
• Comparative analysis with the type strain may reveal specific adaptations for extreme environments.
• This study contributes to the understanding of extremophiles and their potential applications.
