Complete chloroplast genome sequences of Impatiens macrovexilla and I. macrovexilla var. yaoshanensis (Balsaminaceae)

Both Impatiens macrovexilla and I. macrovexilla var. yaoshanensis have potential to be exploited as ornamental plants, despite some of their morphological differences. In the present study, the complete chloroplast genome sequences of the two taxa are reported for the first time, which could facilitate their infraspecies classification, and analyses of their evolution, phylogeny, and breeding potential. The chloroplast genomes of I. macrovexilla and I. macrovexilla var. yaoshanensis were 152,437 and 152,286 bp in size, respectively. Their total GC contents were 36.77 and 36.80%, respectively. Both genomes contained 88 protein-coding genes, 8 rRNA genes, and 37 tRNA genes. The phylogenetic analysis revealed that the two specimens clustered next to each other and were closely related to I. alpicola, I. fanjingshanica, and I. piufanensis, but relatively distant from I. guizhouensis and I. pritzelii.
