Summary
This summary is machine-generated.The first complete chloroplast genome of Oxytropis kansuensis was sequenced, revealing its structure and gene content. This genomic data provides a foundation for understanding the medicinal plant
Area Of Science
- Plant genomics
- Molecular evolution
- Medicinal botany
Background
- Oxytropis kansuensis possesses significant medicinal and ecological importance.
- A lack of complete chloroplast genome data hindered comprehensive understanding and utilization of O. kansuensis.
Purpose Of The Study
- To sequence and de novo assemble the complete chloroplast genome of Oxytropis kansuensis for the first time.
- To analyze the structural characteristics and gene content of the O. kansuensis chloroplast genome.
- To investigate the phylogenetic relationships within the Oxytropis genus using chloroplast genome data.
Main Methods
- Whole-genome sequencing of O. kansuensis.
- De novo assembly of the chloroplast genome.
- Gene annotation including protein-coding genes (PCGs), tRNA, and rRNA.
- Phylogenetic analysis using complete chloroplast genome sequences of related species.
Main Results
- The complete chloroplast genome of O. kansuensis was assembled with a length of 127,115 bp and a GC content of 34.29%.
- The inverted repeat (IR) region was found to be absent in this species.
- A total of 110 genes were annotated: 76 PCGs, 30 tRNA, and 4 rRNA genes.
- Phylogenetic analysis confirmed distinct monophyletic lineages for Oxytropis and Astragalus, with O. kansuensis closely related to O. ochrocephala.
Conclusions
- The sequencing and assembly of the O. kansuensis chloroplast genome provide crucial genomic resources.
- The findings establish a foundation for future research on O. kansuensis, including its medicinal properties and evolutionary history.
- This study contributes valuable data for broader phylogenetic and evolutionary investigations within the Oxytropis genus.

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...
Proteins targeted to the inner chloroplast membrane, or plastid proteins, are transported by two general pathways: the stop-transfer and the re-insertion or post-import pathways. Most plastid proteins carry N-terminal transit sequences and internal import sequences targeting it to the specific chloroplast subcompartment. Proteins targeted by the stop-transfer pathway have internal hydrophobic sequences that inhibit their translocation into the stroma. As a result, these precursors are arrested...
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...
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.

Chloroplast outer membrane proteins encoded by the nucleus are synthesized in the cytosol. Soon after synthesis, they bind cytosolic factors such as 14-3-3 protein and the Hsp70 chaperones that keep these precursors in an unfolded state until their translocation.
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
