Characterization of the complete chloroplast genome of Quercus virginiana Mill. (Fagaceae)

Abstract

The complete chloroplast genome of Quercus virginiana was sequenced with Illumina HiSeq 2000 platform. It was a typical quadruple structure as other plants of Quercus with 161,221 bp in length, including a large single-copy (LSC: 90,553 bp) region and a small single-copy (SSC: 19,016 bp) which were separated by a pair of inverted repeats (IRa, b: 25,826 bp) region. The overall GC content is 36.9%. A total of 131 genes was annotated which contained 86 protein-coding genes including the Trans splicing gene of rps12, 37 tRNA genes, and 8 rRNA genes. ML phylogenetic analysis compared with 17 expressed chloroplast genomes revealed that Q. virginiana was a sister to other species of Quercus, which were grouped together with five species of Section Quercus and another 12 species of Quercus were divided into another group.
