Abstract

Dolichandrone spathacea(L. F.) K. Schum. is an excellent tree species for coastal protection forests. In this study, the complete chloroplast genome sequence of D. spathacea was obtained through high-throughput sequencing. The length of chloroplast genome was 159,156 bp in length, containing a large single-copy region (LSC) of 86,053 bp, a small single-copy region (SSC) of 12,635 bp, and a pair of inverted repeats (IRa and IRb) regions of 30,234 bp. The chloroplast genome with 37.95% GC content, contained 134 genes, including 90 protein-coding genes, 8 rRNA genes, and 36 tRNA genes. Phylogenetic analysis with the reported chloroplast sequences shows that D. spathacea is more closely related to Spathodea campanulata.
