摘要：
Orinus thoroldii is an important alpine grass endemic to the western Qinghai-Tibet Plateau in China, which has high ecological and genetic values. Here, we first assembled the complete chloroplast (cp) genome of O. thoroldii based on sequences from Illumina HiSeq4000 platform. We obtained the cp genome with the total length of 134,205 bp. It is a standard quadripartite structure composed of the large (LSC, 79,699 bp) and small (SSC, 12,458 bp) single copy regions separated by a pair of inverted repeats (IRs, 21,024 bp each). The cp genome encodes 136 genes including 81 protein-coding genes, 44 tRNAs genes and eight rRNAs genes. The overall GC content of the cp genome is 38.4%. The phylogenetic analysis indicated that O. thoroldii is sister to Eragrostis tef in Chloridoideae.
