The complete chloroplast genome of Persicaria maackiana (Regel) Nakai ex T. Mori (Polygonaceae) in Korea

Persicaria maackiana (Regel) Nakai ex T. Mori (1922), a species of the Polygonaceae family, is an annual plant widely distributed in Northeast Asia. We aimed to sequence the complete chloroplast genome of P. maackiana using Illumina HiSeq paired-end sequencing. The chloroplast genome was determined to be 160,635 bp. The complete chloroplast genome contained 129 genes, including 84 protein-coding genes, 37 tRNA, and eight rRNA genes. Phylogenetic analysis of the chloroplast genome sequences of 15 Polygonaceae plants revealed that P. maackiana was most closely related to P. perfoliata. Our findings might be useful for future phylogenetic studies of Polygonaceae.

桃叶蓼（Persicaria maackiana (Regel) Nakai ex T. Mori, 1922）隶属于蓼科（Polygonaceae），是一种广泛分布于东北亚的一年生草本植物。本研究采用Illumina HiSeq双端测序（paired-end sequencing）技术，对该物种的完整叶绿体基因组（chloroplast genome）进行测序。经测定，该叶绿体基因组全长为160635碱基对（bp），共包含129个基因，其中包括84个蛋白编码基因、37个转运RNA（tRNA）基因以及8个核糖体RNA（rRNA）基因。对15种蓼科植物的叶绿体基因组序列开展系统发育分析（phylogenetic analysis）后发现，桃叶蓼与穿叶蓼（Persicaria perfoliata）的亲缘关系最为密切。本研究结果可为未来蓼科植物的系统发育研究提供参考依据。
