Sammanfattning

Solanaceae are a particularly interesting angiosperm family, not only because they include many major crop species such as potato, tomato, eggplant, pepper, tobacco and ornamentals like petunias, but also because numerous species are used as biological models. They have been widely used for understanding crop genetics and plant genome evolution in general. Sequencing efforts have been concentrated mostly to sequence genomes of important crop species of Solanaceae to understand the links between wild and cultivated members of the family. We present the complete plastome of African nightshade (Solanum scabrum Mill.) a hexaploid (2n = 6x = 72) species of the S. nigrum L. complex or Solanum sect. Solanum, a widely cultivated species across Africa. Recent studies highlight S. scabrum as a “super-vegetable” for its nutritional and environmental benefits with potential of global importance. The leaves and berries are the source of coloring plant extracts, inks and dyes, and they are rich in proteins, fibres, iron, vitamins and amino acids. Using 12,413,264 paired end reads deposited in the sequence read archive (SRA) we have assembled the plastid genome sequence of African nightshade with an estimated coverage of 123×. The plastid genome sequence had a total size of 155,522 bp, typical of Solanaceae with a large single copy (LSC) region of 85,896 bp and small single copy (SSC) region of 18,406 bp while the IRs comprised of 25,610 bp. We illustrate the role of Solanum scabrum and its comparative plastomics across Solanaceae and Convolvulaceae to understand the plastomics of Solanales.
