Complete chloroplast genome sequences of Sinosenecio baojingensis Ying Liu & Q.E. Yang (Asteraceae)

Abstract

In this study, we assembled and described the complete chloroplast genome (cp) of Sinosenecio baojingensis Ying Liu & Q.E. Yang (Asteraceae) for the first time. The cp genome is 151,315 bp in length and exhibits a typical quadripartite structure, consisting of a large single-copy (LSC) region of 83,445 bp, a small single-copy (SSC) region of 18,172 bp, and a pair of inverted repeat regions (IRs) of 24,849 bp. A total of 133 genes were annotated, including 88 protein-coding genes (one pseudo gene), 37 tRNA genes (tRNAs), and eight ribosomal RNA genes (rRNAs). Further, the phylogenetic analysis based on eight complete chloroplast genomes indicates that S. baojingensis is shown to be a sister to S. jishouensis. The complete chloroplast genome of S. baojingensis provides significant molecular markers for the studies on phylogeny and species identification of this genus.
