ABSTRACT
Wrightia laevis Hook. f. is a great tree of Apocynaceae. It is mainly distributed in Southeast provinces of China and Southeast Asian countries. It is a plant that combines dyestuff and economic value. There is no study on the genome of W. laevisso far. Here we report and characterize the complete plastid genome sequence of W. laevis in order to provide genomic resources useful for promoting its conservation. The complete chloroplast genome of W. laevis is 155,274 bp in length with a typical quadripartite structure, consisting of a large single-copy region (LSC, 85,463 bp), a single-copy region (SSC, 18,181 bp) and a pair of inverted repeats (IRs, 25,815 bp). There are 133 genes annotated, including 88 unique protein-coding genes, 8 unique ribosomal RNA genes, and 37 transfer RNA genes. The overall G/C content in the plastome of W. laevis is 38.05%. The complete plastome sequence of W. laevis will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Apocynaceae.
ABSTRACT
Caesalpinia sappan Linnaeus is a great tree of Fabaceae. It is mainly distributed in the Southern provinces of China and Southeast Asian countries. It can be used to extract dyes. The heartwood has dyestuff and medicinal value. There is no study on the genome of C. sappan so far. Here, we report and characterize the complete plastid genome sequence of C. sappan in an order to provide genomic resources useful for promoting its conservation. The complete chloroplast genome of C. sappan is 160,176 bp in length with a typical quadripartite structure, consisting of a large single-copy region (LSC, 89,710 bp), a single-copy region (SSC, 18,357 bp), and a pair of inverted repeats (IRs, 26,054 bp). There are 129 genes annotated, including 84 unique protein-coding genes, eight unique ribosomal RNA genes, and 37 transfer RNA genes. The overall G/C content in the plastome of C. sappan is 36.0%. The complete plastome sequence of C. sappan will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Apocynaceae.
ABSTRACT
Callicarpa nudiflora Vahl is a medicinal plant occurring in Guangdong, Guangxi, Hainan provinces of China. Here, we report and characterize the complete plastid genome sequence of C. nudiflora in an effort to provide genomic resources useful for promoting its conservation. The complete plastome is 154,080 bp in length and contains the typical structure and gene content of angiosperm plastome, including two inverted repeat (IR) regions of 25,657 bp, a large single-copy (LSC) region of 84,949 bp, and a small single-copy (SSC) region of 17,817 bp. There are 113 genes annotated, including 79 unique protein-coding genes, 4 unique ribosomal RNA genes, and 30 transfer RNA genes. To investigate the evolution status of C. nudiflora, as well as Verbenaceae, we constructed a phylogenetic tree with C. nudiflora and other 11 species based on their complete chloroplast genomes. According to the phylogenetic topologies, C. nudiflora was closely related to Lancea hirstua.
