Complete chloroplast genome sequence of Solanum mochiquense, one of the tuber-bearing potato relatives

Abstract

Solanum mochiquense is one of the wild tuber-bearing Solanum species belonging to the Solanaceae family. In this study, the chloroplast genome sequence of the species was completed with Illumina sequencing technology. The total length of the chloroplast genome is 155,547 bp with a GC content of 37.87%. It comprises a large single copy (LSC) region of 85,941 bp, a small single copy (SSC) region of 18,382 bp, and two inverted repeat regions (IRa and IRb) of 25,612 bp. Additionally, 158 functional genes in the genome were identified, including 105 protein-coding genes, eight ribosomal RNA genes, and 45 transfer RNA genes. Phylogenetic analysis revealed that S. mochiquense is grouped into a large clade with other Solanum species including cultivated potatoes (S. tuberosum). This study provides useful genomic information for future breeding and evolutionary studies of S. mochiquense and other Solanum species.
