The complete chloroplast genome of the dove tree Davidia involucrata (Nyssaceae), a relict species endemic to China

The dove tree, Davidia involucrate, with its distinguishing pair of white bracts, is endemic to China. Here, we reported the complete chloroplast (cp) genome sequence and the cp genomic features of D. involucrata. The D. involucrata cp genome was 169,196 bp long, with 129 genes comprising 83 protein-coding genes (PCG), 40 tRNA genes, and six rRNA genes. The majority of the gene species occurred as a single-copy, while 18 gene species occurred in double copies, including six PCG species (ndhB, rpl2, rpl23, rps7, rps15, and ycf2), eight tRNA species (trnH-GTG, trnL-CAA, trnI-CAT, trnV-GAC, trnL-GAV, trnA-UGC, trnN-GTT, and trnR-ACG) and all four rRNA species (rrn4.5, rrn5, rrn16, and rrn23). A neighbor-joining (NJ) phylogenetic tree was reconstructed with sequences of complete cp, revealing that D. involucrata belongs to the asterids. The complete cp genome of D. involucrata will be useful for further investigations and the conservation of this endemic relict woody plant.
