Complete plastome sequence of Torenia concolor Lindley (Linderniaceae): an ornamental herb

Abstract

In this study we firstly reported the complete chloroplast genome of Torenia concolor, a species of Linderniaceae. The complete chloroplast genome of T. concolor is 153,853 bp in length with a typical quadripartite structure, consisting of a large single-copy region (LSC, 85,446 bp), a single-copy region (SSC, 18,837 bp), and a pair of inverted repeats (IRs, 24,785 bp). There are 114 genes annotated, including 80 unique protein-coding genes, 4 unique ribosomal RNA genes, and 30 transfer RNA genes. To investigate the evolution status of T. concolor, as well as Linderniaceae, we constructed a phylogenetic tree with T. concolor and other 16 species based on their complete chloroplast genomes. According to the phylogenetic topologies, T. concolor was closely related to Pedicularis hallaisanensis.
