Abstract

Corylopsis microcarpa H.T. Chang 1960 is a relict species from China. The chloroplast genome of C. microcarpa is 159,438 bp in size and shows typical quadripartite structure, which includes a pair of inverted repeat regions (26,280 bp), a large single-copy region (88,185 bp), and a small single-copy region (18,693 bp). The whole chloroplast genome encodes 114 unique genes, including 80 protein-code genes, 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. Ninety-one SSRs were identified. The phylogenetic analysis revealed C. microcarpa diverged early in Corylopsis.

Keywords: Corylopsis microcarpa; chloroplast genome; endemic species; phylogenetic relationship.
