The complete chloroplast genome sequence of Quercus schottkyana, and comparative analysis with related species

Abstract

In this study, we sequenced the complete chloroplast genome of Quercus schottkyana. The circular genome is 160,746 bp in size, featuring a typical quadripartite structure comprising one large single-copy region (LSC, 90,136 bp), one small single-copy region (SSC, 18,942 bp), and two copies of inverted repeat regions (IRs, 25,834 bp). The genome contains 131 genes, including 86 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes. The overall GC content is 36.90%. The maximum likelihood phylogenetic tree reconstructed using IQ-TREE indicated that Q. schottkyana has a closer relationship with Quercus sichourensis and Quercus acuta.
