The complete chloroplast genome sequence of Quercus stewardiana (Fagaceae)

Abstract

Quercus stewardiana A.Camus is an East Asian evergreen oak tree species belonging to Quercus section Cyclobalanopsis. In this study, we assembled and annotated the complete chloroplast (cp) genome of the species. The circular genome is 160,842 bp in size, presenting a typical quadripartite structure including two copies of inverted repeat (IR) regions (25,823 bp), one large single-copy (LSC) region (90,294 bp), and one small single-copy (SSC) region (18,902 bp). It encodes a total of 114 unique genes, including 80 protein-coding genes, 30 tRNA genes, and four rRNA genes. Phylogenetic analysis based on cp genome sequences of 35 Fagaceae species indicated that Q. stewardiana was more closely related to Q. myrsinifolia.
