Abstract

Sea buckthorn (Hippophae rhamnoides), a hardy deciduous shrub of the Elaeagnaceae family, grows wild at high altitudes in Asia and Europe and is known for its excellent nutritional, medicinal, and ecological value. However, research on its chloroplast genome is limited. In this study, we sequenced, assembled, and annotated the chloroplast genomes of four subspecies of H. rhamnoides. The structure, nucleotide diversity, simple and long repeat sequence sites, and codon bias of their chloroplast genomes were compared. Their chloroplast genomes (size range 156,185–156,510 bp) consisted of a pair of inverted repeats (IR) sequences (26,658–26,664 bp) separating a small single-copy region (19,025–19064 bp) from a large single-copy region (83,842–84,118 bp). Gene order, IR boundaries, codon usage, and repetitive sequence distribution showed similarities across the four genomes. Except for H. rhamnoides subsp. mongolica ‘wulanshalin’, which was missing the matK gene, the subspecies contained 131 genes, including 85 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. We also uncovered 373 cpSSRs, 175 long repeat sequences, and 9 regions with high variability worth substantiation in future population genetics research. Meanwhile, a phylogenetic tree of the Elaeagnaceae family was constructed from CDSs, showing that all Hippophae taxa were clustered in the same group and formed a sister clade with Elaeagnus taxa. Among the Hippophae taxa, H. gyantsensis, H. neurcar, and H. salicifolia were grouped, but H. tibetana was clustered with H. rhamnoides. The findings of this research will be helpful for further investigations on resource protection and the taxonomic classification of sea buckthorn.
