, also called Chinese wingnut in China, is a tall deciduous tree of the walnut family (Juglandaceae). is one of the most popular shade trees owing to its tall and graceful form and rapid growth rate. In the present study, the chloroplast genome of was assembled and analyzed phylogenetically. The chloroplast genome of is 160,212 bp in length, with a large single-copy region (LSC) of 88,724 bp, a small single-copy region (SSC) of 18,396 bp, and a pair of inverted repeat regions (IRs) of 26,046 bp, forming a typical quadripartite structure. A total of 130 genes are annotated from the chloroplast genome of , including 82 protein-coding genes, 40 transfer RNA (tRNAs) genes, and 8 ribosomal RNA (rRNAs) genes. The GC content of the chloroplast genome is 36.2%. Phylogenetic analysis based on the common proteins from and 14 related species confirmed the close relationship between Pterocarya and Juglans.
在我国也被称为枫杨，是胡桃科（Juglandaceae）的一种高大落叶乔木。由于其高大优美的树形和快速的生长速度，它是最受欢迎的遮荫树之一。在本研究中，对枫杨的叶绿体基因组进行了组装并进行了系统发育分析。枫杨的叶绿体基因组长度为160,212 bp，有一个88,724 bp的大单拷贝区域（LSC）、一个18,396 bp的小单拷贝区域（SSC）和一对26,046 bp的反向重复区域（IRs），形成典型的四分体结构。从枫杨的叶绿体基因组中共注释出130个基因，包括82个蛋白质编码基因、40个转运RNA（tRNA）基因和8个核糖体RNA（rRNA）基因。叶绿体基因组的GC含量为36.2%。基于枫杨和14个相关物种的共有蛋白质进行的系统发育分析证实了枫杨与胡桃属之间的密切关系。
