The Complete Chloroplast Genome Sequence Of Trikeraia Hookeri

Trikeraia hookeri is an alpine grass with significant ecological value. Here, the complete chloroplast genome sequence of T. hookeri using Illumina sequencing data was reported. The size of the whole cp genome was 137,696 bp in length, consisting of a pair of inverted repeats (IR 13,755 bp), a large single-copy region (LSC 81,613 bp), and a small single-copy region (SSC 28,568 bp). The T. hookeri chloroplast genome encodes 119 genes: 81 mRNA genes, 34 tRNA genes and 4 rRNA genes. The GC content of T. hookeri chloroplast genome was 38.8% and those in LSC, SSC, and IR regions were 36.9, 40.8, and 42.3%, respectively. The maximum-likelihood phylogenetic analysis demonstrated that T. hookeri was most closely related to Stipa lipskyi (NC028444) and Stipa purpurrea (NC029390). Our findings provide fundamental information for further evolutionary and phylogenetic researches of T. hookeri.
