Characteristics and phylogenetic analysis of the complete chloroplast genome of Viburnum japonicum (Adoxaceae)

Abstract

Abstract Viburnum japonicum (Thunb.) Sprengel is a unique and endangered species in the family Adoxaceae and is endemic to the coastal region of Eastern Asia (China, Japan, and South Korea). However, its systematic position remains controversial. Here, we characterized and reported a second complete chloroplast genome of V. japonicum using the Illumina NovaSeq platform. The total length of the chloroplast genome is 158,606 bp with G + C contents of 38.08%, including a large single-copy (LSC) region, a small single-copy (SSC) region, and a pair of inverted repeats (IRs) regions with lengths of 87,060 bp, 18,510 bp, and 26,516 bp, respectively. Phylogenetic analysis revealed that the two accessions of V. japonicum were close related to a clade of V. setigerum, V. erosum, and V. fordiae within the genus Viburnum.
