RESUMO
Dracocephalum rupestre (tribe Mentheae; Lamiaceae) is a perennial herb from Korea and China with high ornamental and medicinal value. Here, we report its complete chloroplast genome to provide insight into the phylogenetic relationships of Dracocephalum. The genome is 151,230 bp long, with two inverted repeat regions (25,643 bp each) that separate a large single-copy region (82,536 bp) and a small single-copy region (17,408 bp). It contains 133 genes that encode 88 proteins, eight rRNAs, and 37 tRNAs. The maximum-likelihood phylogenetic analysis strongly supported Dracocephalum monophyly, showing that the genus forms a sister group with the subtribe Menthinae in the tribe Mentheae.
RESUMO
In this study, we sequenced the complete plastid genome (plastome) of Neolitsea aciculata, an evergreen broad-leaved tree endemic to East Asia, a woody component of East Asian warm-temperate and subtropical forests across China, Korea, and Japan. The plastome of N. aciculata is assembled as a single contig (152,722 bp). A large and a small single copy (93,785 and 18,795 bp, respectively) of the genome are separated by a pair of inverted repeats (20,071 bp). The genome consists of 126 genes, including 80 protein-coding, eight ribosomal RNA, and 36 transfer RNA genes. Two genes in the IR region (ycf1 and ycf2) are pseudogenized. Our phylogenetic analysis revealed the phylogenetic position of N. aciculata in a highly supported clade of the genus Neolitsea along with other two congeners, N. pallens and N. sericea.
