Abstract
Roscoea tibetica is a most widespread and extensively phenotypic-variable alpine ginger species. Here, we reported the complete chloroplast (cp) genome sequence of R. tibetica. The complete chloroplast genome is 163,515 base pairs (bp) in length, containing two inverted repeat (IRa and IRb) regions of 29,781 bp, which was separated by a large single-copy (LSC) region of 88,090 bp and a small single-copy (SSC) region of 15,863 bp. The overall GC content of the plastid genome was 36.06%. In total, 113 unique genes were annotated, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenetic analysis based on 22 chloroplast genomes indicates that R. tibetiaca is closely related to R. humeana, forming a monophyletic group with high value.
