Complete chloroplast genome sequence of the wild diploid potato relative, Solanum acaule

Abstract

Solanum acaule is a wild tuber-bearing species classified in the Solanaceae. The complete chloroplast genome of S. acaule was constructed by de novo assembly using Illumina paired-end (PE) sequencing data. The chloroplast genome of S. acaule is circular and has a length of 155,570 bp and typical quadripartite consisting of 86,020 bp of large single copy, 18,364 bp of small single copy, and 25,593 bp of a pair of inverted repeat regions. A total of 158 genes were annotated including 105 protein-coding genes, 45 tRNA genes, and eight rRNA genes. Maximum likelihood phylogenetic analysis of the sequence with 31 species in the Solanaceae revealed that S. acaule is fully resolved in a large clade with nine other Solanum species including S. tuberosum.
