Viburnum erosum is a deciduous shrub distributed in eastern Asia. As part of the systematic study to understand the phylogenetic relationship of V. erosum, we present the complete chloroplast genome of V. erosum. Its length is 158,624 bp and it has four subregions: 87,060 bp of large single-copy and 18,530 bp of small single-copy regions separated by a pair of inverted repeat regions of 26,517 bp each, including 129 genes (84 protein-coding genes, 8 rRNAs, and 37 tRNAs). Phylogenetic analyses show that V. erosum is sister to Viburnum japonicum, supporting morphological affinity of the two species.

2020) The second complete chloroplast genome sequence of the Viburnumerosum (Adoxaceae) showed a low level of intra-species variations, Mitochondrial DNA Part B, 5:1, 271-272, ABSTRACT We presented the second complete chloroplast genome of the plant. The length of chloroplast genome is 158,587 bp, consisting of four subregions: 87,050 bp of LSC and 18,503 bp of SSC regions separated by a pair of 26,517 bp IR regions. It includes 129 genes (84 protein-coding genes, 8 rRNAs, and 37 tRNAs). A low-level of molecular variation within Viburnum erosum was found with 16 SNPs and 49 indels. The phylogenetic tree shows that the two accessions of V. erosum are clustered with Viburnum japonicum with no resolution between the species, suggesting that chloroplast genome in these species evolve slowly.

Stellera chamaejasme is a toxic perennial herb found in open and dry places in East Asia and has the potential for new drugs for anti-inflammatory, analgesic, and cutaneous wound-healing purposes. Here, we present the complete chloroplast genome of S. chamaejasme. Its length is 173,381 bp and has four subregions; 86,769 bp of large-single-copy and 2,858 bp of small-single-copy regions are separated by 41,877 bp of inverted repeat regions, including 135 genes (89 protein-coding genes, 8 rRNAs, and 38 tRNAs). Phylogenetic trees show that S. chamaejasme is a sister to Daphne kiusiana, supporting morphological affinity of the two species. ARTICLE HISTORY

Halenia corniculata, characterized by having yellow corollas with spurs at the base within Halenia, is an endangered species in Korea, which represents the southern limit of the distribution range of the species. We present the complete chloroplast genome of H. corniculata. Its length is 153,198 bp and it has four subregions; 83,252 bp of large-single-copy and 18,372 bp of small-single-copy regions are separated by 25,787 bp of inverted repeat, including 130 genes (85 protein-coding genes, 8 rRNAs, and 37 tRNAs). Phylogenetic trees show that H. corniculata is a sister to S. bimaculata, nested within Swertia, consistent with previous phylogenetic studies.
