Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes02:16

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...
Animal Mitochondrial Genetics02:59

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...
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 irrespective...
Non-nuclear Inheritance01:29

Non-nuclear Inheritance

Most DNA resides in the nucleus of a cell. However, some organelles in the cell cytoplasm⁠—such as chloroplasts and mitochondria⁠—also have their own DNA. These organelles replicate their DNA independently of the nuclear DNA of the cell in which they reside. Non-nuclear inheritance describes the inheritance of genes from structures other than the nucleus.
Diversity of Protists I01:15

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
Diversity of Protists II01:27

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Summary

Mitochondrial genomes offer insights into Platyzoa

Area of Science:

  • Zoology
  • Genomics
  • Evolutionary Biology

Background:

  • Platyzoa is a diverse group of small, worm-shaped animals within the spiralian clade.
  • The evolutionary relationships within Platyzoa, including the monophyly of Platyzoa and subgroups like Platyhelminthes, Gastrotricha, and Gnathifera, are subjects of ongoing debate.
  • Understanding these relationships is crucial for comprehending metazoan evolution.

Purpose of the Study:

  • To review the contribution of complete mitochondrial (mt) genome data to resolving phylogenetic debates within Platyzoa.
  • To highlight unique features of platyzoan mt genomes and discuss challenges in their phylogenetic analysis.
  • To provide a comprehensive survey of published platyzoan mt genomes.

Main Methods:

  • Review of existing scientific literature on platyzoan mitochondrial genomes.
Keywords:

  • Analysis of published mitochondrial genome data to assess phylogenetic utility.
  • Tabular compilation of all available platyzoan mitochondrial genome information.
  • Main Results:

    • Mitochondrial genome data appear insufficient to definitively place Platyzoa within the broader Spiralia.
    • However, mt genome data can be valuable for addressing internal phylogenetic questions within the Platyzoa clade.
    • Special features of mt genomes and potential issues in phylogenetic analyses using mtDNA are discussed.

    Conclusions:

    • Complete mitochondrial genomes are a valuable, though not universally sufficient, tool for understanding Platyzoa phylogeny.
    • Further research incorporating diverse genomic data may be necessary to fully resolve the evolutionary history of Platyzoa.
    • The review provides a crucial resource for future studies on Platyzoa evolution.
