Characterization of the complete chloroplast genome of Pterocarya stenoptera, a tall deciduous tree of the family Juglandaceae

Pterocarya stenoptera, also called Chinese wingnut in China, is a tall deciduous tree of the walnut family (Juglandaceae). P. stenoptera is one of the most popular shade trees owing to its tall and graceful form and rapid growth rate. In the present study, the chloroplast genome of P. stenoptera was assembled and analyzed phylogenetically. The chloroplast genome of P. stenoptera is 160,212 bp in length, with a large single-copy region (LSC) of 88,724 bp, a small single-copy region (SSC) of 18,396 bp, and a pair of inverted repeat regions (IRs) of 26,046 bp, forming a typical quadripartite structure. A total of 130 genes are annotated from the chloroplast genome of P. stenoptera, including 82 protein-coding genes, 40 transfer RNA (tRNAs) genes, and 8 ribosomal RNA (rRNAs) genes. The GC content of the chloroplast genome is 36.2%. Phylogenetic analysis based on the common proteins from P. stenoptera and 14 related species confirmed the close relationship between Pterocarya and Juglans.
