Abstract

The complete chloroplast genome sequence of Populus tremula was characterized from Illumina pair-end sequencing. The chloroplast genome of P. tremula was 156,862 bp in length, containing a large single-copy region (LSC) of 84,971 bp, a small single-copy region (SSC) of 16,605 bp, and two inverted repeat (IR) regions of 27,640 bp. The overall GC content is 30.69%, while the correponding values of the LSC, SSC, and IR regions are 64.5%, 69.3%, and 60.1%, respectively. The genome contains 131 complete genes, including 86 protein-coding genes (62 protein-coding gene species), 37 tRNA genes (29 tRNA species) and 8 rRNA genes (4 rRNA species). The Neighbour-joining phylogenetic analysis showed that P. tremula and Populus davidiana clustered together as sisters to other Populus species.

摘要

根据Illumina的双端测序技术，对白杨的完整叶绿体基因组序列进行了表征。的叶绿体基因组P.欧洲山杨的长度为156862个碱基，含84971个碱基，小单拷贝区16605个碱基对（SSC），以及两个的27640反向重复（IR）区域的大单拷贝区（LSC） bp。总GC含量为30.69％，而LSC，SSC和IR区域的对应值分别为64.5％，69.3％和60.1％。该基因组包含131个完整基因，包括86个蛋白质编码基因（62个蛋白质编码基因种类），37个tRNA基因（29个tRNA种类）和8个rRNA基因（4个rRNA种类）。邻区系统发育分析表明，金银假单胞菌和山杨聚集在一起，成为其他胡杨树种的姐妹。
