Complete chloroplast genome data of Plumbago auriculata f. alba (Pasq.) Z. X. Peng, a medicinal and ornamental species

<i>Plumbago auriculata</i> f. <i>alba</i> (Pasq.) Z. X. Peng, a perennial evergreen shrub, is evaluated for both its medicinal properties and ornamental value. It is usually used to treat inflammatory disorders and skin infections, while its white flowers make it a popular landscape plant. In this study, the complete chloroplast genome of <i>Plumbago auriculata</i> f. <i>alba</i> (Pasq.) Z. X. Peng was sequenced using the Illumina HiSeq platform. The circular chloroplast genome has a total length of 169,357 (bp), exhibiting the typical quadripartite structure of angiosperms: a large single-copy (LSC) region of 92,056 bp, a small single-copy (SSC) region of 13,321 bp, and two inverted repeat (IR) regions (IRa and IRb) each of 31,990 bp. A total of 129 genes were annotated, including 84 protein-coding genes (PCGs), 37 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. Simple sequence repeat (SSR) analysis identified 104 SSR loci, with mononucleotide repeats (73 loci, 70.19 %) being the most abundant, attended by trinucleotide repeats (13 loci, 12.5 %). Phylogenetic tree showed that <i>P. auriculata</i> f. <i>alba</i> (Pasq.) Z. X. Peng is most closely related to <i>Plumbago auriculata</i> with 100 % bootstrap support. These chloroplast genome data enrich the genetic resources of Plumbaginaceae, providing a foundation for molecular breeding, genetic diversity analysis, and phylogenetic research of <i>Plumbago auriculata</i> complex.
