Abstract

High-throughput sequencing of chloroplast genomes has been used to gain insight into the evolutionary relationships of plant species. In this study, we sequenced the complete chloroplast genomes of four species in the Meconopsis genus: M. racemosa, M. integrifolia (Maxim.) Franch, M. horridula and M. punicea. These plants grow in the wild and are recognized as having important medicinal and ornamental applications. The sequencing results showed that the size of the Meconopsis chloroplast genome ranges from 151864 to 153816 bp. A total of 127 genes comprising 90 protein-coding genes, 37 tRNA genes and 8 rRNA genes were observed in all four chloroplast genomes. Comparative analysis of the four chloroplast genomes revealed five hotspot regions (matK, rpoC2, petA, ndhF, and ycf1), which could potentially be used as unique molecular markers for species identification. In addition, the ycf1 gene may also be used as an effective molecular marker to distinguish Papaveraceae and determine the evolutionary relationships among plant species in the Papaveraceae family. Futhermore, these four genomes can provide valuable genetic information for other related studies.
