Abstract:
The whole chloroplast genome (cp DNA) sequence of Acer davidii Franch has been characterized from Illumina pair-end sequencing. The complete cpDNA was 157,044 bp in length, containing a large single copy region (LSC) of 85,410 bp and a small single copy region (SSC) of 18,112 bp, which were separated by a pair of 26,761 bp inverted repeat regions (IRs). The cpDNA contained 134 genes, including 86 protein-coding genes (78 PCG species), forty tRNA genes (31 tRNA species) and eight ribosomal RNA genes (four rRNA species). The most of gene species occur as a single copy, while 21 gene species occur in double copies. The overall AT content of A. davidii cpDNA is 62.1 %, while the corresponding values of the LSC, SSC and IR regions are 63.9, 67.7 and 57.3 %, respectively. The phylogenetic analysis suggested that the sampled Acer species formed a monophyletic clade, and the cpDNA of A. davidii is closely related to that of congeneric A. morrisonense.
