Complete chloroplast genome of Zanthoxylum avicennae (Lam.) DC (Rutaceae: Zanthoxylum).

In this study, the chloroplast (Cp) genome of Zanthoxylum avicennae (Lam.) DC was sequenced by high-throughput sequencing technology. The length of the Cp genome of Zanthoxylum avicennae was 158,568 bp, and the total GC content was 38.4%, including a large single-copy (LSC) region of 86,318 bp, a small single-copy (SSC) region of 18,250 bp, and 27,000 bp of inverted repeats (IRs). The Cp genome encoded 131 genes, including 88 protein-coding, 37 tRNA, and six rRNA genes. Phylogenetic analysis of the genome sequence showed that Zanthoxylum avicennae was closely related to Zanthoxylum nitidum, Zanthoxylum esquirolii and Zanthoxylum motuoense of the Rutaceae family.

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 sequences of Zanthoxylum nitidum var. nitidum and Z. nitidum var. tomentosum.

Zanthoxylum nitidum (Rutaceae Juss.) is a traditional Chinese medicine with four morphological types. We assembled their complete chloroplast genome sequences. The assembled genomes are 156,999-157,349 bp in length, including a large single copy (LSC) region of 84,064-84,455 bp, a small single copy (SSC) region of 17,582-17,651 bp and a pair of inverted repeats (IRs) of 27,631-27,659 bp. All genomes contained 133 genes, including 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. The GC content is 38.5%. The further phylogenetic analysis showed that Z. nitidum clade was a monophyletic group separated from other Zanthoxylum species.

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.

The complete chloroplast genome of Zanthoxylum acanthopodium DC. (Rutaceae) and its phylogenetic analysis.

We sequenced the complete chloroplast genome of Zanthoxylum acanthopodium via high-throughput sequencing technology, and analyzed its structural characteristics and phylogenetic relationships. The chloroplast exhibits a genome length of 158,473 bp, including a pair of inverted repeat regions (IRa and IRb) of 27,369 bp, a small single-copy (SSC) region of 17,629 bp and a large single-copy (LSC) region of 85,570 bp. The annotation analysis identified 112 genes, containing 78 protein-coding genes, 30 tRNA genes and 4 rRNA genes. The phylogenetic analysis showed that Z. acanthopodium was closely related to Z. piperitum and Z. tragodes.
