Complete chloroplast genome sequence of Solanum iopetalum, one of the tuber-bearing wild potato relatives.

ABSTRACT: Solanum iopetalum belongs to the Solanaceae family and is one of the tuber-bearing wild Solanum 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 S. iopetalum is grouped into a large clade with other Solanum species, including cultivated potatoes (S. tuberosum) and is closely related to Mexican Solanum species (S. stoloniferum, S. verrucosum, S. hougasii, S. hjertingii, and S. demissum). This study provides useful genomic information for future breeding and evolutionary studies of S. iopetalum and other Solanum species.
