Summary
Researchers created a database of 105 annotated genomes from minimal genome strains of Bacillus subtilis. This resource aids in understanding cellular components and their interactions for basic science and biotechnology applications.
Area of Science:
- Microbiology
- Genomics
- Synthetic Biology
Background:
- Understanding cellular life requires deciphering component contributions and interactions.
- Minimal genomes are crucial tools for studying these cellular mechanisms.
- Bacillus subtilis is an industrially relevant model bacterium.
Purpose of the Study:
- To create a comprehensive database of annotated genomes for a series of Bacillus subtilis strains with sequential genome deletions.
- To support the MiniBacillus project by providing a valuable genomic resource.
- To facilitate research in basic science and biotechnology.
Main Methods:
- Generation of 105 fully annotated genomes from sequential deletion strains of Bacillus subtilis.
- Sequencing of key intermediate strains to support annotation.
- Integration of literature knowledge for annotating deletion scars and their effects.
Main Results:
- A database of 105 annotated genomes representing the MiniBacillus project strain compendium.
- Characterization of Bacillus subtilis strains with up to 40% genome reduction (e.g., B. subtilis PG38).
- Detailed annotation including deletion scars and their potential functional impact.
Conclusions:
- The presented genome library is a comprehensive resource for the MiniBacillus project.
- This resource will enhance the application of minimal genome strains in scientific research.
- Facilitates deeper understanding of cellular functions and potential biotechnological advancements.

45.5K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains.

01:24Bacterial Phylum Tenericutes
174
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Prokaryotic genomes exhibit a streamlined organization of coding and non-coding regions essential for gene expression and protein synthesis. While coding regions contain the genetic instructions for proteins or functional RNAs, non-coding regions regulate the precise transcription and translation of these genes.Coding Regions: Proteins and RNAsThe primary coding regions, known as structural genes, include sequences transcribed into messenger RNA (mRNA) and ultimately translated into...

03:21Genome Size and the Evolution of New Genes
8.5K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Proteobacteria, one of the largest and most diverse bacterial phyla, encompasses a wide range of Gram-negative bacteria distinguished by their outer membrane composed of lipopolysaccharides. These microorganisms exhibit various metabolic capabilities, including phototrophy, chemolithotrophy, and heterotrophy, and thrive in diverse environments from soil to aquatic systems and host-associated niches. The phylum is divided into six classes: Alphaproteobacteria, Betaproteobacteria,...
