Complete chloroplast genome sequence of Solanum hjertingii, one of the wild potato relatives

Solanum hjertingii is a wild tuber-bearing species classified in the Solanaceae family. The chloroplast genome of S. hjertingii was completed via de novo assembly using Illumina paired-end sequencing data. Total length of the chloroplast genome of S. hjertingii is 155,545 bp consisting of 85,976 bp in a large single copy, 18,383 bp in a small single copy, and 25,593 bp in a pair of inverted repeat regions. Its structure is circular and typically quadripartite. It contains 158 predicted genes in total, including 105 protein-coding, 45 tRNA, and eight rRNA genes. Maximum likelihood phylogenetic analysis of the sequence along with 33 species in the Solanaceae family revealed that S. hjertingii belongs to a large clade with other Solanum species including S. tuberosum and is most closely grouped in the clade with S. hougasii and S. stoloniferum in the clade.
