| Abstract: |
Oreomecon nudicaulis, commonly known as mountain poppy, is a significant perennial herb. In 2022, the species O. nudicaulis, which was previously classified under the genus Papaver, was reclassified within the genus Oreomecon. Nevertheless, the phylogenetic status and chloroplast genome within the genus Oreomecon have not yet been reported. This study elucidates the chloroplast genome sequence and structural features of O. nudicaulis and explores its evolutionary relationships within Papaveraceae. Using Illumina sequencing technology, the chloroplast genome of O. nudicaulis was sequenced, assembled, and annotated. The results indicate that the chloroplast genome of O. nudicaulis exhibits a typical circular quadripartite structure. The chloroplast genome is 153,903 bp in length, with a GC content of 38.87%, containing 84 protein-coding genes, 8 rRNA genes, 38 tRNA genes, and 2 pseudogenes. The genome encodes 25,815 codons, with leucine (Leu) being the most abundant codon, and the most frequently used codon is AUU. Additionally, 129 microsatellite markers were identified, with mononucleotide repeats being the most abundant (53.49%). Our phylogenetic analysis revealed that O. nudicaulis has a relatively close relationship with the genus Meconopsis within the Papaveraceae family. The phylogenetic analysis supported the taxonomic status of O. nudicaulis, as it did not form a clade with other Papaver species, consistent with the revised taxonomy of Papaveraceae. This is the first report of a phylogenomic study of the complete chloroplast genome in the genus Oreomecon, which is a significant genus worldwide. This analysis of the O. nudicaulis chloroplast genome provides a theoretical basis for research on genetic diversity, molecular marker development, and species identification, enriching genetic information and supporting the evolutionary relationships among Papaveraceae.
