Complete chloroplast genome of the Oriental white oak: Quercus aliena Blume.

The complete chloroplast (cp) genome sequence of the Oriental white oak: Quercus aliena Blume, the first sequenced member of the section Quercus, is reported in this study. The length of cp genome size is 160,921 bp, with 36.9% GC content. A pair of 25,841 bp inverted repeat regions (IRs) is separated by a 90,258 bp large single copy region (LSC) and an 18,980 bp small single copy region (SSC). This genome contains 115 unique genes, including 89 coding genes, four rRNA genes, and 39 tRNA genes. Border analysis of cp genome of Quercus aliena and other 10 most closely related cp genomes revealed that most Fagaceae species have high similarity either in structure or distribution of these genes except for Trigonobalanus doichangensis.
