RESUMO
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.
RESUMO
The first complete chloroplast genome (cp) of Sinosenecio jishouensis D.G. Zhang, Ying Liu & Q. E. Yang (Asteraceae) was sequenced and assembled in this study. The cp genome was 151,257 bp in length, including a large single-copy(LSC) region of 83,373 bp, a small single-copy (SSC) region of 18,178 bp, and a pair of inverted repeat (IR) regions of 24,853 bp each. These sequences encoded 134 genes, including 89 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogenetic analysis based on 18 complete cp sequences revealed that S. jishouensis was closely related to Eclipta prostrata.
