Abstract:
In this study, complete chloroplast genome of Solanum nigrum, a wild relative of potato and tomato being important for its medicinal features, was sequenced. The genome size is 154 671 bp in length, with 40% GC content. A pair of inverted repeats, IRa and IRSb, were separated by a large single-copy region and a small single-copy region of 82 315 bp and 33 411 bp, respectively. The genome harbored 73 protein-coding genes, 36 tRNA genes, and three rRNA genes. The evolutionary relationships in our phylogenetic analysis revealed that S. nigrum is closer to S. tuberosum when compared with those of known relatives' species belonging to Solanum genus.
