Characterization of the complete chloroplast genome sequence of Lycium qingshuiheense (Solanaceae).

ABSTRACT

Lycium qingshuiheense is a typical drought and salt-alkali-tolerant plant, which has been added to the new species of Lycium in recent years. Here, we first sequenced the complete chloroplast genome of L. qingshuiheense to investigate its evolutionary relationship within the family Solanaceae. Results suggested that the circular complete chloroplast genome of L. qingshuiheense was 154,945 bp in length, including a large single-copy (LSC) of 85,930 bp, a small single-copy (SSC) of 18,203 bp, and two inverted repeats (IRs) of 25,406 bp. The GC content accounts for 37.90% and annotated 131 genes, including 86 protein-coding genes, eight rRNA genes, and 37 tRNA genes. A neighbor-joining phylogenetic tree revealed that L. qingshuiheense was a sister species to L. ruthenicum. Our study provides a new insight into the systematic evolution of Lycium in the Solanaceae family.
