Complete chloroplast genome sequences of two species used for Tibetan medicines, Meconopsis punicea vig. and M. henrici vig. (Papaveraceae)

Abstract

Meconopsis Vig. is a genus possessing important medicinal and ornamental values in the Papaveraceae. Many species in this genus are commonly used in traditional Tibetan medicines over thousands of years. In this study, we sequenced complete chloroplast (cp) genome sequences of two species, namely Meconopsis punicea and M. henrici to investigate their phylogenetic relationships in Papaveraceae. Total lengths of the chloroplast genomes were 153,281 bp and 153,388 bp, respectively. Both of the two genomes had typical quadripartite structure, LSC region (83,999 bp and 83,698 bp) and SSC region (17,730 bp and 17,822 bp) were separated by a pair of IRs (25,776 bp and 26,107 bp), respectively. Moreover, they were composed of 112 genes, including 78 protein coding genes, 30 tRNA genes, three rRNA genes and one pseudogene. Phylogenetic analysis based on complete chloroplast genomes showed that M. henrici had closer relationship with M. racenosa than M. punicea; meanwhile, Meconopsis was closely related to Papaver in Papaveraceae.
