Abstract:
In nature, the fruit fly frequently encounters various pathogens that cause a decrease in host fitness. Here, we present the genome sequence of Serratia marcescens strain FY, which was isolated from the intestines of a Drosophila specimen. The complete genome sequence comprises one chromosome of 5,074,453 bp and two plasmids of 100,934 bp and 87,789 bp. A total of 4,891 coding sequences are predicted from this assembly.
Insights
We sequenced the genome of Serratia marcescens strain FY, isolated from fruit flies. This provides a valuable resource for understanding insect-pathogen interactions and host defense mechanisms.
Area of Science:
- Microbiology
- Genomics
- Insect Pathology
Background:
- Fruit flies (Drosophila) are susceptible to various pathogens, impacting host fitness.
- Serratia marcescens is a known opportunistic pathogen that can infect insects.
Purpose of the Study:
- To present the complete genome sequence of Serratia marcescens strain FY.
- To provide a genomic resource for studying fruit fly-Serratia marcescens interactions.
Main Methods:
- Isolation of Serratia marcescens strain FY from a Drosophila specimen's intestines.
- Whole-genome sequencing and assembly of the bacterial strain.
- Bioinformatic analysis to predict coding sequences.
Main Results:
- The complete genome sequence of Serratia marcescens strain FY was determined.
- The genome consists of a chromosome (5,074,453 bp) and two plasmids (100,934 bp and 87,789 bp).
- A total of 4,891 coding sequences were predicted.
Conclusions:
