Complete plastome sequence of Pandanus tectorius Parkinson ex Du Roi (Pandanaceae)

摘要

Pandanus tectorius Parkinson ex Du Roi (Pandanaceae) is a tree or shrub which is widely distributed in seashores and sandy beaches in Fujian, Guangdong, Guangxi, Guizhou, Hainan, Taiwan, Yunnan Provinces of China. P. tectorius sometimes is used as a living fence, the leaves are used for weaving and the fruit is beneficial for the treatment of diabetes. Here, we report and characterize the complete plastid genome sequence of P. tectorius in an effort to provide genomic resources useful for promoting its conservation. The complete plastome is 159,362?bp in length and contains the typical structure and gene content of angiosperm plastome, including two inverted repeat (IR) regions of 26,702?bp, a large single-copy (LSC) region of 87,447?bp and a small single-copy (SSC) region of 18,511?bp. The plastome contains 114 genes, consisting of 80 unique protein-coding genes, 30 unique tRNA genes, and 4 unique rRNA genes (5S rRNA, 4.5S rRNA, 23S rRNA, and 16S rRNA). The overall A/T content in the plastome of P. tectorius is 62.40%. The complete plastome sequence of P.tectorius will provide a useful resource for the conservation genetics of this species as well as for the phylogenetic studies of Pandanaceae.
