The complete chloroplast genome of Pyrus calleryana (GenBank OM541581.1) was developed by de novo assembly from whole-genome sequencing data. Reference-guided (P. phaeocarpa) read mapping and assembly were followed by annotation and phylogenetic comparisons. The 159,965 bp P. calleryana chloroplast genome represented 36.56% GC content with a classical quadripartite architecture and two inverted repeats regions (IRs; each 26,392 bp) separating the large single-copy region (LSC; 87,942 bp) and the small single-copy region (SSC; 19.239 bp). In total, 125 unique features were annotated in that genome, including 83 protein coding genes, 38 tRNA coding genes, and 4 rRNA coding genes. Phylogenetic analyses based on the whole chloroplast genome sequences placed the P. calleryana among other Rosaceae plants, specifically among the Asian species of Pyrus.

Pyrus calleryana (GenBank OM541581.1)的完整叶绿体基因组是通过全基因组测序数据的从头组装开发的。参考引导 ( P. phaeocarpa ) 读取映射和组装之后是注释和系统发育比较。159,965 bp 的P. calleryana叶绿体基因组代表 36.56% 的 GC 含量，具有经典的四分结构和两个反向重复区域（IR；每个 26,392 bp）将大单拷贝区域（LSC；87,942 bp）和小单拷贝区域分开（SSC；19.239 bp）。在该基因组中总共注释了 125 个独特的特征，包括 83 个蛋白质编码基因、38 个 tRNA 编码基因和 4 个 rRNA 编码基因。基于全叶绿体基因组序列的系统发育分析P. calleryana在其他蔷薇科植物中，特别是在亚洲梨属植物中。
