Summary
This study presents a high-quality genome assembly for Ichthyurus bourgeoisi, a beetle species. This genomic resource aids in understanding the evolution and ecological adaptations of the Ichthyurini tribe.
Area of Science:
- Genomics
- Evolutionary Biology
- Entomology
Background:
- Ichthyurus bourgeoisi is a representative of the brachelytrous beetle tribe Ichthyurini (Cantharidae).
- Limited genomic data hinders understanding of Ichthyurini evolution and adaptation.
Purpose of the Study:
- To generate a chromosome-level genome assembly for Ichthyurus bourgeoisi.
- To provide a foundational genomic resource for studying beetle evolution and adaptation.
Main Methods:
- PacBio HiFi and Hi-C sequencing technologies were employed.
- Bioinformatic analyses were used for assembly, scaffolding, and gene annotation.
Main Results:
- A 664.72 Mb genome assembly was produced, organized into seven pseudo-chromosomes, including chromosome X.
- The assembly contains 65.35% repeat sequences and 13,386 protein-coding genes.
- High metrics for genome size, read mapping, and BUSCO completeness (98.6%) validate the assembly quality.
Conclusions:
- The high-quality genome assembly of I. bourgeoisi is a valuable resource.
- This resource will facilitate research into the ecological adaptations and morphological evolution of Ichthyurini beetles.

03:36Genome Annotation and Assembly
21.3K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

777.2K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

25.5K
Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...

00:58Genomic DNA in Eukaryotes
53.7K
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

4.9K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...
