Complete chloroplast genome sequence of Carpinus oblongifolia (Betulaceae) and phylogenetic analysis

摘要

Carpinus oblongifolia (Betulaceae) is a critically endangered species endemic to Jiangsu. In this study, the complete chloroplast (cp) genome of C. oblongifolia was assembled based on next-generation sequencing. The cp genome was 159,086?bp in length, including a large single-copy (LSC) region of 88,190?bp, a small single-copy (SSC) region of 18,765?bp and a pair of inverted repeats (IRs) of 26,066 and 26,067?bp, respectively. The genome contained 124 genes, including 85 protein-coding genes, 30 tRNA genes, and 8 ribosomal RNA genes. The overall GC content of the chloroplast genome was 36.49%. A phylogenetic analysis demonstrated a close relationship between C. oblongifolia and Ostrya rehderiana .
