Characterization of the complete plastid genome of Draba oreades (Brassicaceae)

Abstract

Draba oreades is one of the indicator species that narrowly distributed in alpine habitats. Here, the complete plastid genome (plastome) of D. oreades was determined by Illumina paired-end sequencing technology. It was 153,503 bp in length with a large single copy region of 82,683 bp, a small single copy region of 18,094 bp, and a pair of inverted repeat regions of 26,363 bp. A total of 129 genes were identified, including 84 protein-coding genes (78 PCG species), 37 tRNA genes (30 tRNA species), and 8 rRNA genes (4 rRNA species). The overall GC content of D. oreades plastome is 36.5%. Besides, we totally detected 116 perfect simple sequence repeats in D. oreades plastome. Maximum likelihood phylogenetic analysis based on 27 complete plastome sequences revealed that D. oreades was closely related to its congeneric D. nemorosa.
