The whole chloroplast genome of Psathyrostachys huashanica (Gramineae), a rare and endangered herb species endemic to China

Psathyrostachys huashanica Keng belongs to the genus Psathyrostachys within the Gramineae family, is a rare and endangered herb plant endemic to China. In the current work, we first developed its whole chloroplast (cp) genome sequence. The cp genome of P. huashanica is 136,632 bp in size, including a large single copy (LSC) region of 81,803 bp, a small single copy (SSC) region of 12,763 bp, and a pair of inverted repeats (IRs) of 21,033 bp. The genome contains 114 genes, including 78 protein-coding genes, 32 tRNA genes, and 4 rRNA genes. The GC content in cp genome, LSC, SSC, and IR regions were 38.5, 36.5, 32.6, and 38.5%, respectively. The phylogenetic analysis showed P. huashanica is closely related to Triticum genus.
