Characterization of the complete chloroplast genome of Hippophae salicifolia D. Don (Elaeagnaceae)

Abstract

Seabuckthorn (Hippophae L.) is a pioneer species widely distributed in Eurasia. We assembled and annotated the chloroplast genome of Hippophae salicifolia from Illumina pair-end data, which was 155,420 bp in length with 36.74% GC content; this plastome featured a quadripartite structure with two copies of a large inverted repeat (IR) of 26,528 bp separated by large single copy (LSC) region of 83,504 bp and small single copy region (SSC) of 18,860 bp. In total, 131 complete genes were annotated, including 38 tRNA, eight rRNA, and 85 protein-coding genes. Phylogenetic analysis recovered H. salicifolia and H. gyantsensis as monophyletic and sister to all other Hippophae species for which complete plastome sequences have been published.
