Abstract

Populus pruinosa Schrenk plays an important role on ecological services in desert areas. The complete chloroplast genome was reported in this study using the PacBio Sequel II Platform. The chloroplast genome with a total size of 157,856 bp consists of two inverted repeats (IR, 27,673 bp) separated by a large single-copy region (LSC, 85,867 bp) and a small single-copy region (SSC, 16,645 bp). Further annotation revealed the chloroplast genome contains 111 genes, including 78 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. A total of 151 simple sequence repeats (SSRs) were identified in the chloroplast genome. This information will be useful for study on the evolution and genetic diversity of P. pruinosa in the future.

摘要

毛白杨在荒漠地区的生态服务中起着重要作用。这项研究使用PacBio Sequel II平台报道了完整的叶绿体基因组。叶绿体基因组的总大小为157,856 bp，由两个反向重复序列（IR，27,673 bp）组成，分别由一个大的单拷贝区域（LSC，85,867 bp）和一个小的单拷贝区域（SSC，16,645 bp）隔开。进一步注释显示，叶绿体基因组包含111个基因，包括78个蛋白质编码基因，29个tRNA基因和4个rRNA基因。在叶绿体基因组中鉴定出总共151个简单序列重复（SSR）。这些信息对于将来研究P. pruinosa的进化和遗传多样性将是有用的。
