Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes02:16

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

12.0K
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 Genes

3.6K
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...

The Antenna Complex01:42

The Antenna Complex

5.9K
Plants and other photosynthetic organisms comprise pigments capable of absorption of direct sunlight. These pigments are present in the reaction center - the main site of photochemical reactions as well as in the antenna complex. Under average light conditions, the rate at which reaction center pigments absorb light is far below the electron transport chain's capacity. As a result, the reaction center alone cannot provide enough energy to drive photosynthesis. The photosynthetic efficiency...

Main Results:

  • The complete chloroplast genome of A. sylvatica was successfully sequenced, measuring 151,161 bp with a GC content of 38%.
  • The genome comprises large single-copy (LSC), small single-copy (SSC), and inverted repeat (IR) regions, containing 132 genes (87 protein-coding, 37 tRNA, 8 rRNA).
  • Phylogenetic analysis confirmed A. sylvatica's placement within the subgenus Artemisia.

Conclusions:

  • This study reports the first complete chloroplast genome sequence for A. sylvatica.
  • The generated genomic data significantly expands the available resources for the Artemisia genus.
  • The findings provide insights into the evolutionary history and genetic makeup of A. sylvatica.
