Abstract
Solanum stoloniferum is a wild tuber-bearing species belonging to Solanaceae family. The complete chloroplast genome of S. stoloniferum was constituted by de novo assembly using a small amount of whole genome sequencing data. The chloroplast genome of S. stoloniferum was the circular DNA molecule with a length of 155,567 bp and consisted of 86,007 bp of large single copy, 18,374 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 with 25 Solanaceae species revealed that S. stoloniferum is the most closely grouped with S. tuberosum.
Highlights
Solanum stoloniferum is a wild tuber-bearing species belonging to Solanaceae family
The species is sexually incompatible with S. tuberosum due to different endosperm balance numbers (EBNs) with EBN values of 2 and 4 in S. stoloniferum and S. tuberosum, respectively, both species are tetraploid (Brown 1988; Singsit and Hanneman 1991; Ortiz and Ehlenfeldt 1992; Cho et al 1997)
The wild species is difficult to be applied to potato breeding and somatic hybridization could be one of the solutions to overcome sexual barriers for interspecific gene transfer (Bidani et al 2007; Nouri-Ellouz et al 2016) and importance to identify chlorotype with information of chloroplast genome sequences in potato breeding program has increased (Chen et al 2013, 2016; Cho and Park 2016; Cho et al 2016; Molnar et al 2017)
Summary
Solanum stoloniferum is a wild tuber-bearing species belonging to Solanaceae family. The complete chloroplast genome of S. stoloniferum was constituted by de novo assembly using a small amount of whole genome sequencing data.
