The complete chloroplast genome of Ostericum palustre (Apiaceae)

Abstract

Ostericum palustre is a critically Endangered species endemic to Europe and was described as the type-species of the genus Ostericum (Apiaceae). The complete chloroplast genome of O. palustre was reported for the first time, which suggested a circle quadripartite structure of 154923 bp in length comprising the large single-copy region (LSC) of 84750 bp, the small single-copy region (SSC) of 19752 bp, and a pair of inverted regions (IRs) of 25209 bp. There were totally 127 genes including 4 rRNAs, 37 tRNAs, and 82 protein-coding genes. In the phylogenetic analyses, O. palustre was very close to Pterygopleurum neurophyllum but distant from Angelica species, which coincided with the result of ITS sequences analysis. This study provided a significant genetic resource and will be helpful to systematic research and effective conservation.
