Complete plastid genome of Primula calliantha Franch. (Primulaceae): an alpine ornamental plant endemic to Hengduan Mountain, China

摘要

Primula calliantha Franch. is an alpine species with an ornamental value that is endemic to the Hengduan Mountains of southwest China. Here, we sequenced and assembled its plastid complete genome, which is a circular molecule of 151,954?bp and contains a large single-copy (83,820?bp) and a small single-copy (17,814?bp) region, separated by a pair of inverted repeats (25,160?bp). There are 131 genes, 86 protein-coding, 37 tRNAs, and 8 rRNAs in the plastome, of which 114 genes, 80 CDSs, 30 tRNAs, and 4 rRNAs are unique, respectively. The P. calliantha plastid genome shows a high level of synteny with its close relatives, P. chionantha , P. purdomii , and P. woodwardii . Phylogenetic analysis based on 60 complete chloroplast genomes of Primulaceae confirmed its delimitation in Primula .
