Insights

The mite Histiostoma blomquisti uses fire ants for dispersal. Its newly sequenced mitogenome reveals evolutionary insights, placing it as an early lineage within Astigmata mites.

Area of Science:

  • Mitochondrial genomics
  • Acarology
  • Evolutionary biology

Background:

  • Histiostoma blomquisti mites feed on microorganisms and utilize the red imported fire ant (Solenopsis invicta) for dispersal.
  • Understanding mite mitogenomes provides insights into their evolutionary history and genetic makeup.

Purpose of the Study:

  • To sequence and characterize the mitogenome of Histiostoma blomquisti.
  • To investigate the phylogenetic position of H. blomquisti within the Astigmata mite group.

Main Methods:

  • Next-generation sequencing was employed to obtain the H. blomquisti mitogenome.
  • Phylogenetic analysis was conducted using the concatenated nucleotide sequences of 13 protein-coding genes.

Main Results:

  • The complete mitogenome of H. blomquisti was determined to be 15,892 bp in size.
  • The mitogenome comprises 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs, and 6 non-coding regions.
  • Phylogenetic analysis indicated that Histiostomatid mites represent the basal-most lineage within Astigmata.

Conclusions:

  • The mitogenome sequence provides a valuable resource for future studies on H. blomquisti and related species.
  • The findings support the basal phylogenetic position of Histiostomatid mites within Astigmata, contributing to mite evolutionary understanding.

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Export of Mitochondrial and Chloroplast Genes02:19

Export of Mitochondrial and Chloroplast Genes

A eukaryotic cell can have up to three different types of genetic systems: nuclear, mitochondrial, and chloroplast. During evolution, organelles have exported many genes to the nucleus; this transfer is still ongoing in some plant species. Approximately 18% of the Arabidopsis thaliana nuclear genome is thought to be derived from the chloroplast’s cyanobacterial ancestor, and around 75% of the yeast genome derived from the mitochondria’s bacterial ancestor. This export has occurred...

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Genomic DNA in Eukaryotes

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.
