Other claims from this paper (11)
- Observation The chloroplast genome of the tetraploid Polygala vulgaris was reported for the first time.
- Observation Assembled chloroplast genome sizes of the studied Polygala taxa ranged from 165,246 bp to 168,779 bp.
- Observation A total of 174 genes were annotated in the Polygala vulgaris chloroplast genome.
- Observation The Polygala vulgaris chloroplast genome contains 102 protein-coding genes.
- Observation The Polygala vulgaris chloroplast genome contains 63 transfer RNA genes.
- Observation The Polygala vulgaris chloroplast genome contains 13 ribosomal RNA genes.
- Observation Nine highly divergent genes were identified, including the CDS gene rpl32 and several intergenic spacer regions.
- Observation The most similar relative of Polygala vulgaris was the European taxon P. amerella, with high support values.
- Observation Relative synonymous codon usage in Polygala vulgaris was largely consistent with other Polygala species.
- Observation Three types of repeat sequences (forward, palindromic, reverse) were identified across the analyzed chloroplast genomes.
- Recommendation The authors state the findings are a valuable reference for phylogenomics and evolution of Polygala taxa and for developing DNA barcoding markers.
