Abstract

Carex myosuroides Villars, 1779 is a typical alpine sedge with both ecological and agricultural value. The work reported here is the first complete chloroplast genome of this species. The chloroplast genome, with a total size of 185,609 bp, consists of two inverted repeats (IRs, 38,374 bp) separated by a large single-copy (LSC, 99,911 bp) region, and a small single-copy (SSC, 8950 bp) region. The overall genome GC content is 34.12%. The genome contains 125 genes, consisting of 82 protein-coding genes, 35 tRNA genes, and eight rRNA genes. Phylogenetic analysis supports the taxonomic treatment of incorporating genus Kobresia to a broader circumscription of Carex. Our work could be helpful to future research on Cyperaceae.

Keywords: Carex myosuroides; Cyperaceae; alpine; complete chloroplast genome.
