The complete chloroplast genome of Dombeya wallichii (Malvaceae).

Dombeya wallichii, which was recently introduced to China, possesses unique ornamental value. The aim of this study was to obtain the complete chloroplast genome sequence of D. wallichii using the high-throughput sequencing (NGS) on the Illumina HiSeq 6000 platform, thereby supporting its taxonomic and evolutionary research. The chloroplast genome in D. wallichii exhibited a total length of 161,278 bp, with the structural organization comprising four distinct components: a large single-copy (LSC) region spanning 89,968 bp, a small single-copy (SSC) segment measuring 20,448 bp, and two inverted repeat (IR) regions each extending 25,431 bp. Regarding base composition analysis, the LSC region displayed a GC content of 34.3%, while the SSC and IR regions showed respective values of 30.8% and 43.1%.The phylogenetic analysis showed that D. wallichii was closely related to the Corchoropsis species and shared a common ancestor.
