Characterization of the complete chloroplast genome of Cornus bretschneideri (cornaceae).

Cornus bretschneideri L.Henry (Cornaceae), a shrub or small tree, is a potential horticultural plant or a soil-fixing plant. In this study, the complete sequence and characterization of the chloroplast genome of C. bretschneideri was studied. The size of the chloroplast genome is 158,270 bp in length, including a large single copy region (LSC) of 87,466 bp, a small single copy region (SSC) of 18,730 bp, and a pair of inverted repeat (IR) regions with 26,037 bp. The GC content of the chloroplast genome was 37.86%. Moreover, a total of 132 functional genes were annotated, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The neighbor-joining phylogenetic tree suggested that C. bretschneideri was closely related to C. sanguinea and C. macrophylla.
