Complete chloroplast genome of Angelica hirsutiflora Liu et al. 1961 (Apiaceae)

TL;DR

This study sequenced and analyzed the complete chloroplast genome of Angelica hirsutiflora, a plant native to Taiwan, to better understand its evolutionary relationships.

Contribution

The paper presents the first complete chloroplast genome of Angelica hirsutiflora and its phylogenetic placement within the genus Angelica.

Findings

The chloroplast genome is 154,266 bp in size with specific structural features like IRs, LSC, and SSC regions.

Phylogenetic analysis revealed A. hirsutiflora forms a distinct clade, separate from other Angelica species.

The genome contains 114 genes, including 80 protein-coding, 30 tRNA, and four rRNA genes.

Abstract

Angelica hirsutiflora Liu et al.1961, is a perennial herb in the Apiaceae family that is endemic to Taiwan. In this study, the complete circular chloroplast genome of A. hirsutiflora was reconstructed and annotated using Illumina sequencing. The size of the chloroplast genome is 154,266 bp, consisting of two inverted repeats (IRs, 25,075 bp) separated by a large single-copy region (LSC, 86,569 bp) and a small single-copy region (SSC, 17,547 bp). The GC content of the chloroplast genome is 37.6%. There are 114 different genes in the chloroplast genome of A. hirsutiflora, including 80 protein-coding genes, 30 tRNA genes and four rRNA genes. A maximum-likelihood phylogenetic analysis showed that A. hirsutiflora forms a distinct clade, and separated from other species within the genus Angelica. This study provided insights into the evolutionary relationships among different species of Angelica.
