Abstract

Myricaria elegans, an endemic species to the Himalayas, is a distinctive deciduous shrubbery plant-primarily distributed in the Qinghai-Tibet Plateau and adjacent regions in China. It is a kind of fuelwood, medicinal, and ecology-protecting woody plant species. In this study, the whole chloroplast (cp) genome sequence of M. elegans was assembled and characterized by high-throughput sequencing data. The complete cp genome of M. elegans was 155,245 bp in length with a GC content of 37.4%. It contained a large single-copy region (LSC) of 84,846 bp, and a small single-copy region (SSC) of 18,290 bp, which were separated by a pair of 26,053 bp inverted repeat regions (IRs). The cp genome of M. elegans was composed of 130 genes, including 85 protein-coding genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. Phylogenetic analysis revealed that M. elegans formed a clade with Myricaria, and it showed a close relationship with Myricaria prostrata.
