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.

Automated summary

This study assembled and analyzed the chloroplast genome of Solanum hjertingii, a wild tuber-bearing species. The genome was found to be circular in structure and contain multiple genes. Phylogenetic analysis revealed a close relationship between S. hjertingii and other species in the Solanum genus.
