Abstract

Elymus alashanicus (Keng) S. L. Chen, a herbaceous plant endemic to China, plays a crucial role in the local ecosystems. In this study, we sequenced and characterized the complete chloroplast (cp) genome of E. alashanicus, which is 135,072 bp in length and arranged in a circular form. The cp genome includes a pair of inverted repeats (IRa and IRb) of 20,813 bp each, separated by a large single-copy (LSC) region of 80,678 bp and a small single-copy (SSC) region of 12,768 bp. The cp genome contains 130 genes, including 83 protein-coding genes, 39 tRNA genes, and eight rRNA genes. Phylogenetic analysis revealed that E. alashanicus is closely related to Elymus breviaristatus and Campeiostachys dahurica var. tangutorum in current sampling. Our findings provide valuable insights into the cp genome of E. alashanicus, which could contribute to further studies on the evolution and conservation of this species.

Keywords: Chloroplast genome; Elymus alashanicus (Keng) S. L. Chen; phylogenetic analysis.
