Three annotated chromosome-level de novo genome assemblies of Lomentospora prolificans provide evidence for a

Insights

Lomentospora prolificans, a drug-resistant fungus causing severe infections, has had its genome fully sequenced. This breakthrough offers hope for developing new antifungal treatments and understanding its evolution.

Area of Science:

  • Mycology
  • Genomics
  • Infectious Diseases

Background:

  • Lomentospora prolificans is a fungal pathogen causing severe, often fatal, infections in immunocompromised individuals.
  • Existing antifungal drugs are largely ineffective against L. prolificans due to inherent resistance.

Purpose of the Study:

  • To generate chromosome-level de novo genome assemblies for Lomentospora prolificans.
  • To provide the first complete genome assembly of L. prolificans.
  • To aid in the discovery of novel antifungal drugs and understand fungal evolution.

Main Methods:

  • Chromosome-level de novo genome assembly of three L. prolificans strains.
  • Genome annotation.
  • Pulsed-field gel electrophoresis for assembly confirmation.

Main Results:

  • The first complete genome assembly of L. prolificans was achieved.
  • The genome comprises 11 nuclear and 1 mitochondrial chromosome, totaling 36.7-37.1 Mb.
  • A chromosomal translocation was identified in one strain, supported by contig variations.

Conclusions:

  • The availability of complete L. prolificans genomes is crucial for antifungal drug development.
  • These genomic resources provide insights into the evolutionary history of this challenging pathogen.

Overview of Transposition and Recombination

Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

Lampbrush Chromosomes01:51

Lampbrush Chromosomes

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...

Genome Annotation and Assembly03:36

Genome Annotation and Assembly

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.

DNA-only Transposons02:57

DNA-only Transposons

DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

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.
