The complete chloroplast genome and phylogenetic analysis of Cyperus brevifolius (Rottb.) Hassk. 1844 (Cyperaceae)

Abstract

The medicinal plant Cyperus brevifolius (Rottb.) Hassk. 1844 has a long history of use in traditional Chinese medicine. In this study, we determined and systematically analyzed the complete chloroplast (cp) genome of C. brevifolius. The genome is 183,717 bp in length with a GC content of 33.24%. It comprises four distinct regions: a large-single copy (LSC) region of 101,190 bp, a small-single copy (SSC) region of 10,366 bp, and two inverted repeat (IR) regions of 36,079 bp each. A total of 137 genes are present in the genome including 89 protein-coding genes, 40 tRNA genes, and eight rRNA genes. Phylogenetic analysis reveals that C. brevifolius belongs to the Cyperus genus. This newly sequenced cp genome provides valuable insights for future genetic and genomic studies on Cyperus.
