Chloroplast genome characterization of Rubus arcticus L.

Abstract

Rubus arcticus Linnaeus (1753) is a medicinal and edible plant in the Rosaceae with wide distribution in northeast China. The total length of the genome was 156,668 bp with a GC content of 37.1%, including a large single-copy (LSC, 85,958 bp) region, a small single-copy region (SSC, 18,756 bp), and inverted repeat (IR, 51,954 bp) regions. A total of 129 genes were identified. The numbers of protein genes tRNAs and rRNAs were 85, 36, and 8, respectively. Phylogenetic analysis indicated that R. arcticus belongs to the Rubus genus. Published R. arcticus chloroplast genomes have yielded insights into the closely related species identification, phylogenetic position and Rubus evolution.
