Complete chloroplast genome of Solanum viarum (Solanaceae)

Solanum viarum Dunal, a perennial herb or subshrub belonging to the family Solanaceae, has been naturalized in Korea, forming a sustainable population that has grown naturally with native plants for more than ten years. However, its complete chloroplast genome sequence remains unreported. Therefore, we determined the complete chloroplast genome sequence of S. viarum Dunal via genome sequencing, assembly, and annotation of DNA extracted from fresh S. viarum leaves. The S. viarum genome is 156,209 bp in total length (large single-copy region, 86,877 bp; small single-copy region, 18,494 bp; two inverted repeat regions, 25,419 bp each) with a GC content of 37.8% and 130 genes, including 84 coding DNA sequences, 37 tRNA genes, eight rRNA genes, and one pseudogene (infA). To investigate phylogenetic relationships, a maximum likelihood tree was constructed based on 78 protein-coding genes extracted from the chloroplast genomes of 35 Solanum species. Calystegia soldanella and Calystegia hederacea (Convolvulaceae) were used as the outgroups. The phylogenetic analysis revealed that S. viarum is located within the Acanthophora clade and closely related to S. aculeatissimum. Our results provide genetic information pertaining to S. viarum and elucidate its relationship with related species, thereby offering a molecular foundation for future phylogenetic studies of Solanum.
