The complete chloroplast genome of Primula calliantha subsp. bryophila, an ornamental alpine plant from China

Primula calliantha subsp. bryophila (Balf. f. et Farrer) W.W. Smith and Forrest (1928) is a perennial alpine species with ornamental value. It is distributed in northwestern Yunnan and adjacent eastern Tibet of China, and northern Myanmar. Here, we sequenced and assembled complete plastid genome of P. calliantha subsp. bryophila, which is a circular molecule of 152,045 bp in length, including a large single-copy region (83,966 bp), a small single-copy region (17,663 bp), and a pair of inverted repeats (25,208 bp). The chloroplast genome contained 113 genes, including 79 protein-coding genes, four rRNA genes, and 30 tRNA genes. The phylogenetic tree based on chloroplast genomes showed the relative relationship of P. calliantha subsp. bryophila and P. calliantha, which further supports P. calliantha subsp. bryophila as a subspecies of P. calliantha in taxonomy. The complete chloroplast (cp) genome of P. calliantha subsp. bryophila provides valuable data for further phylogenetic studies of Primulaceae.
