The complete chloroplast genome of Zanthoxylum piasezkii Maxim. (Rutaceae) and its phylogenetic analysis.

Zanthoxylum piasezkii Maxim. is a widely distributed species of edible medicinal plant in China. It has been used for traditional spicy condiment and medicinal ingredients for quite a long time. In this study, the complete chloroplast genome sequence of Z. piasezkii was first reported and characterized from sequencing data. The complete chloroplast genome was determined to be 158,728 bp in length, consisting of a large single-copy (LSC) region (85,918 bp) and a small single copy (SSC) region (17,612 bp), which were separated by a pair of 27,599 bp inverted repeat (IR) regions. The chloroplast genome is predicted to contain 132 genes, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of cpDNA is 38.4%. The phylogenetic analysis of 12 complete chloroplast genomes reveals that Z. piasezkii is mostly related to the congeneric Z. bungeanum.

Complete chloroplast genome sequence of Zanthoxylum nitidum (Rutaceae), an important medicinal shrub.

Zanthoxylum nitidum (Rutaceae) is a scandent prickly shrub and widely distributed in South China. It's well known for its valuable medicinal values due to contains some important secondary metabolites. Here, we first report and characterize its complete chloroplast genome based on Illumina paired-end sequencing data. The complete plastid genome was 157,253 bp, which contained inverted repeats (IR) of 27,618 bp separated by a large single-copy (LSC) and a small single copy (SSC) of 84,382 bp and 17,635 bp, respectively. The cpDNA contains 132 genes, comprising 87 protein-coding genes, 37 tRNA genes, 8 rRNA genes. The overall GC content of the plastome is 38.5%. The phylogenetic analysis of 20 selected chloroplast genomes demonstrated that Z. nitidum is closely related to the congeneric Z. bungeanum.

Characterization of the complete chloroplast genome of Zanthoxylum esquirolii Levl. (Rutaceae).

Zanthoxylum esquirolii Léveillé 1914 is mainly distributed in southwest China, and its wild germplasm resources are scarce and in urgent need of conservation. In this study, we report the first complete chloroplast genome sequence of Z. esquirolii using next-generation sequencing. The circular genome is 158,390 bp in length, containing two inverted repeat (IR) regions of 27,622 bp separated by a large single copy (LSC) region of 85,580 bp and a small single copy (SSC) region of 17,566 bp. The chloroplast genome contains a total of 132 genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the chloroplast genome was 38.46%, with corresponding values in the LSC, SSC, and IR regions of 36.84%, 33.55%, and 42.51%, respectively. The phylogenetic tree revealed that Z. esquirolii Levl. formed a clade with Z. piperitum DC., Z. bungeanum Maxim., Z. simulans Hance and Z. sp. NH-2018, and had a strongly supported sister relationship with Z. bungeanum.

The complete chloroplast genome sequence of Zanthoxylum armatum.

The first complete chloroplast genome sequences of Zanthoxylum armatum were reported in this study. The cpDNA of Z. armatum is 158,579 bp in length, contains a large single copy region (LSC) of 85,780 bp and a small single copy region (SSC) of 17,598 bp, which were separated by a pair of inverted repeat (IR) regions of 27,598 bp. The genome contains 133 genes, including 88 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 38.5%. Phylogenetic analysis of 18 chloroplast genomes within the family Rutaceae suggests that Z. armatum is closely related to Zanthoxylum schinifolium.

The complete chloroplast genome sequence of Zanthoxylum undulatifolium Hemsl. (Rutaceae).

Zanthoxylum undulatifolium is an excellent economic tree species with important medical value. This study reports the first complete chloroplast genome sequence of Z. undulatifolium. Its whole chloroplast genome is 158,400 bp in length, including a large single-copy (LSC) region of 85,898 bp, a small single-copy (SSC) region of 17,610 bp, and two inverted repeat (IR) regions of 27,446 bp. The chloroplast genome contains a total of 132 genes, comprising 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the chloroplast genome is 38.46%, with the corresponding values in the LSC, SSC, and IR regions are 36.87%, 33.51%, and 42.55%, respectively. Phylogenetic analysis revealed the sister relationship between Z. undulatifolium and Z. bungeanum.
