Summary
This summary is machine-generated.The complete chloroplast genomes of two Pachysandra species were sequenced and analyzed. Phylogenetic analysis reveals Pachysandra
Area Of Science
- Plant genomics
- Molecular evolution
- Phylogenetics
Background
- The genus Pachysandra, comprising three species, is of interest for its genetic makeup.
- Understanding the chloroplast genome is crucial for plant evolutionary studies.
Purpose Of The Study
- To assemble and annotate the complete chloroplast genomes of two Pachysandra species.
- To provide foundational data for genetic research within the Pachysandra genus and the Buxaceae family.
Main Methods
- Whole chloroplast genomes were sequenced using the Illumina HiSeq 2500 platform.
- Genome assembly and annotation were performed.
- Maximum-likelihood phylogenetic analysis was conducted using 25 taxa.
Main Results
- The complete chloroplast genomes of Pachysandra axillaris (157,353 bp) and Pachysandra terminalis (160,805 bp) were successfully assembled.
- Both genomes exhibit a typical quadripartite structure and contain numerous genes, including protein-coding, tRNA, and rRNA genes.
- Phylogenetic analysis indicates a close relationship between Pachysandra and Buxus within the Buxaceae family.
Conclusions
- The sequenced chloroplast genomes provide essential genetic resources for Pachysandra.
- This study clarifies the phylogenetic position of Pachysandra within the Buxaceae family.

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...
Green algae and plants, including green stems and unripe fruit, harbor chloroplasts—the vital organelles where photosynthesis takes place. In plants, the highest density of chloroplasts is found in the mesophyll cells of leaves.
A double membrane surrounds chloroplasts. The outer membrane faces the cytoplasm of the plant cell on one side and the intermembrane space of the chloroplast on the other. The inner membrane separates the narrow intermembrane space from the aqueous interior of...
Green algae and plants, including green stems and unripe fruit, harbor specialized organelles called chloroplasts to carry out photosynthesis. They coordinate both stages of photosynthesis — the light-dependent reactions and the light-independent reactions. The light-dependent reactions use sunlight to release oxygen and produce chemical energy in the form of ATP and NADPH, and the light-independent reactions capture CO2 and use ATP and NADPH to produce sugar.

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...
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.
Mitochondria are present in both plants and animal cells. They are regarded as the “powerhouses” of eukaryotic...
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...
