The complete chloroplast genome of <i>Dillenia philippinensis</i> (Dilleniaceae), a near-threatened endemic tree from the Philippines

Genomic resources for <i>Dillenia philippinensis</i> Rolfe, a near-threatened tree species endemic to the Philippines, remain limited despite its significant medicinal, culinary, and ornamental uses. Here, we assembled and characterized the first complete chloroplast (cp) genome of <i>D. philippinensis</i> using Illumina sequencing technology. The cp genome exhibited a typical quadripartite structure with a total length of 161,584 bp, consisting of a large singlecopy region (89,409 bp), a small single-copy region (19,203 bp), and a pair of inverted repeat regions (26,486 bp each). The plastome contains 36 tRNA genes, eight rRNA genes, and 85 protein-coding genes, with an overall GC content of 36.3%. A total of 299 simple sequence repeat loci were identified, and an inverted repeat boundary comparison indicated a highly conserved structure. A phylogenetic analysis revealed close evolutionary relationships among <i>D. philippinensis, D. turbinata</i>, and <i>D. indica</i>, forming a well-supported monophyletic clade. The generated plastome data provide a valuable genomic resource for species identification, comparative genomics, and phylogenetic studies, and establish a baseline for future conservation genetic research, particularly for this near-threatened species.
