Characterization of the complete chloroplast genome of Ligusticum sinense, as a Chinese herb to treat toothache in China

Blog Article

Ligusticum sinense is a popular herb in Chinese medicine.The circular double-stranded Anti-Gas complete chloroplast genome of L.sinense was 146,342 bp in length, exhibiting a typical quadripartite structure.It contained a large single-copy region (LSC) of 91,788 bp, a small single-copy region (SSC) of 17,618 bp and two identical inverted repeat (IR) regions of 18,468 bp each.The overall nucleotide composition of chloroplast genome sequence is: A (30.

8%), T (31.6%), C (19.2%), G (19.4%) and the total G + C content of 38.6%.

The chloroplast genome contained 127 genes, including 83 protein-coding genes, 36 transfer RNA genes and 8 ribosomal Vacuum Circuit Board RNA genes were annotated.The total of 15 genes duplicated in one of the IR, including 6 tRNA, 4 rRNA, and 5 protein-coding genes.The ML phylogenetic tree indicated that L.sinense is closely related to L.tenuissimum in the phylogenetic relationship.
