Abstract
The complete chloroplast genome sequence of Populus davidiana was characterized from Illumina pair-end sequencing. The chloroplast genome of P. davidiana was 156,868 bp in length, containing a large single-copy region (LSC) of 84,976 bp, a small single-copy region (SSC) of 16,606 bp, and two inverted repeat (IR) regions of 27,643 bp. The overall GC content is 30.70%, while the correponding values of the LSC, SSC, and IR regions are 64.6%, 69.2%, 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. davidiana and Populus rotundifolia clustered together as sisters to other Populus species.

杨树(Salicaceae)叶绿体基因组完整序列
摘要
从Illumina的双末端测序技术可以鉴定出杨树的完整叶绿体基因组序列。的叶绿体基因组山杨的长度为156868个碱基,含84976个碱基,小单拷贝区16606个碱基对(SSC),以及两个的27643反向重复(IR)区域的大单拷贝区(LSC) bp。总GC含量为30.70%,而LSC,SSC和IR区域的对应值分别为64.6%,69.2%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)。邻居结合系统发育分析表明,P。davidiana和Populus rotundifolia聚集在一起,成为其他胡杨树种的姐妹。
