Abstract

Solanum betacea is a sub-tropical tree, and the fruit has high nutritional value, unique flavor and color. It is used as a functional ingredient in health care, food, cosmetic and pharmaceutical applications. The complete chloroplast(Cp) genome of S. betacea has been assembled and annotated in this paper. Its length was 155,937 bp, containing a large single-copy region of 86,731 bp, a small single-copy region of 18,450 bp, and a pair of IR regions of 25,378 bp in each. The complete chloroplast genome of S. betacea contained 134 genes, including 90 protein-coding genes, 36 transfer RNA genes (tRNAs), and 8 ribosome RNA genes (rRNAs). The overall GC content was 37.7% and the GC contents of the LSC, SSC, and IR regions were 35.7%, 31.8%, and 43.1%, respectively. Phylogenetic analysis with the reported chloroplast genomes revealed that S. betacea has been most closely related to Solanum torvum. These findings will provide useful information for further investigation of chloroplast genome evolution in Solanum betacea.

Keywords: Solanum betacea; chloroplast genome; phylogenetic.
