RESUMEN
Hypecoum erectum L., a widespread species in northern Eurasia, is a valuable medicinal plant, but its chloroplast genome has not previously been reported. We determined its complete chloroplast genome using a high-throughput sequencing technique. Its total length was 169,241 bp, consisting of a large single-copy region of 93,301 bp and a small single-copy region of 17,316 bp, separated by a pair of inverted repeat regions of 29,312 bp. A total of 140 genes were annotated, including 91 protein coding genes, 41 tRNA genes, and eight rRNA genes. The phylogenetic analysis shows that H. erectum and H. zhukanum of the subfamily Hypecoideae are monophyletic with the highest support.
RESUMEN
Swertia japonica (Schult.) Makino is a traditional medicinal plant in Japan for which the chloroplast genome has not been previously reported. The complete chloroplast genome of S. japonica was determined using a high-throughput sequencing technique. The total length of the S. japonica chloroplast genome was 153,208 bp, and comprised a large single-copy region of 83,319 bp, and a small single-copy region of 18,375 bp, separated by a pair of 25,757 bp inverted repeat regions. A phylogenetic analysis, based on the obtained chloroplast genome, indicated that S. japonica is closely related to S. diluta, S. franchetiana, S. kouitchensis, S. mussotii, and S. punicea. The presented chloroplast genome will be useful for further taxonomic, pharmacological and evolutionary studies of Swertia.
