Characterization of the complete chloroplast genome of Carpinus putoensis

The whole chloroplast (cp) genome sequence of Carpinus putoensis has been characterized from Illumina pair-end sequencing. The complete cp genome was 159,673 bp in length, containing a large single copy region (LSC) of 89,020 bp and a small single copy region (SSC) of 18,568 bp, which were separated by a pair of 26,044 and 26,043 bp inverted repeat regions (IRs). The genome contained 128 genes, including 83 protein-coding genes (75 PCG species), 36 tRNA genes (29 tRNA species) and 8 ribosomal RNA genes (4 rRNA species). The most of gene species occur as a single copy, while 16 gene species occur in double copies. The overall AT content of C. putoensis chloroplast genome is 63.6 %, while the corresponding values of the LSC, SSC and IR regions are 65.8, 69.8 and 57.5 %, respectively. Further, phylogenetic analysis suggested that C. putoensis is closely related to Ostrya rehderiana.
