belongs to the Solanaceae family and is one of the tuber-bearing wild species. In this study, chloroplast genome sequencing of the species, completed with Illumina sequencing technology, is presented. The length of the chloroplast genome is 155,625 bp with a GC content of 37.86%. It comprises a large single copy (LSC) region of 86,057 bp, a small single copy (SSC) region of 18,382 bp, and two inverted repeat regions (IRa and IRb) of 25,593 bp. Additionally, 158 functional genes in the genome are identified, including 105 protein-coding genes, 8 ribosomal RNAs, and 45 transfer RNAs. Phylogenetic analysis revealed that is grouped into a large clade with other species, including cultivated potatoes () and is closely related to Mexican species (, , , , and ). This study provides useful genomic information for future breeding and evolutionary studies of and other species.
属于茄科，是一种块茎野生种。在本研究中，展示了利用Illumina测序技术完成的该物种叶绿体基因组测序。叶绿体基因组长度为155,625 bp，GC含量为37.86%。它包括一个86,057 bp的大单拷贝（LSC）区域、一个18,382 bp的小单拷贝（SSC）区域以及两个25,593 bp的反向重复区域（IRa和IRb）。此外，基因组中鉴定出158个功能基因，包括105个蛋白质编码基因、8个核糖体RNA和45个转移RNA。系统发育分析表明，该物种与其他茄属物种，包括栽培马铃薯（），归为一个大分支，并且与墨西哥茄属物种（、、、、和）密切相关。本研究为该物种及其他茄属物种未来的育种和进化研究提供了有用的基因组信息。
