The complete chloroplast genome sequence of Corylopsis sinensis (Hamamelidaceae)

Corylopsis sinensis Hemsl. is a deciduous shrub endemic to China, which is a valuable medicinal and ornamental species. In this study, we report the complete chloroplast genome sequence of C. sinensis, providing a genomic basis for future research. The chloroplast genome is 159,419 base pairs (bp) in length, with a large single-copy (LSC) region of 88,152 bp, a small single-copy (SSC) region of of 18,701 bp, and two inverted repeat (IR) regions of 26,283 bp. The overall GC content is 38.0% and the chloroplast genome encodes 113 unique genes including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. The phylogenetic results show that C. sinensis is sister to C. spicata. These results of C. sinensis will improve our understanding of the evolution of Corylopsis and Hamamelidaceae.
