High-resolution genetic map and SNP chip for molecular breeding in a tetraploid medicinal plant.

Ginseng () renowned as the king of medicinal plants. Ginseng grows slowly under shade conditions, requiring at least 4 years to produce a limited number of seeds. Molecular breeding of ginseng faces challenges due to its the tetraploid genome and the absence of an efficient molecular marker system.

Cytokinin signaling promotes root secondary growth and bud formation in .

Background: , one of the valuable perennial medicinal plants, stores numerous pharmacological substrates in its storage roots. Given its perennial growth habit, organ regeneration occurs each year, and cambium stem cell activity is necessary for secondary growth and storage root formation. Cytokinin (CK) is a phytohormone involved in the maintenance of meristematic cells for the development of storage organs; however, its physiological role in storage-root secondary growth remains unknown.

A chromosome-level genome assembly of Korean mint (Agastache rugosa).

Agastache rugosa, also known as Korean mint, is a perennial plant from the Lamiaceae family that is traditionally used for various ailments and contains antioxidant and antibacterial phenolic compounds. Molecular breeding of A. rugosa can enhance secondary metabolite production and improve agricultural traits, but progress in this field has been delayed due to the lack of chromosome-scale genome information.

The complete chloroplast genome of cv. Bokjo (Rhamnaceae).

We have sequenced the cv. Bokjo chloroplast genome by assembly using next-generation sequencing. The complete circular chloroplast genome consisted of 161,714 bp and contained four parts: a large single-copy (LSC) region of 89,323 bp, a small single-copy (SSC) region of 19,361 bp, and two inverted repeat regions (IRa and IRb) of 26,515 bp each.

The complete chloroplast genome of cv. Hwang-Moran (Paeoniaceae).

The complete chloroplast genome of cv. Hwang-Moran (PHM), a yellow flowering tree peony, was assembled and characterized from high-throughput next-generation sequencing data. The total length of the circular PHM chloroplast genome was 152,519 bp, including a large single-copy (LSC) region of 84,214 bp, a small single-copy (SSC) region of 17,026 bp, and a pair of inverted repeat regions (IRs) of 25,640 bp.

Development of 18 microsatellite markers for .

Premise: (Asteraceae) is endemic to East Asia, where its rhizomes are used in traditional medicine. To investigate the genetic diversity of this species, we developed polymorphic microsatellite markers.

Methods And Results: We obtained a total of 175,825 simple sequence repeat (SSR) loci using the Illumina HiSeq 2500 system.

The complete chloroplast genome of Pall. (Paeoniaceae).

The complete chloroplast genome sequence of was obtained by assembly using next-generation sequencing. The circular molecule of the genome constituted of four parts, with 152,731 bp in the complete chloroplast genome, including a large single-copy (LSC) region of 84,402 bp, a small single-copy (SSC) region of 16,969 bp, and two inverted repeat (IRa and IRb) regions of 25,680 bp each. The genome annotation predicted a total of 111 genes, including 77 protein-coding genes, 30 tRNA genes, and 4 rRNA genes.

Development of Genome-Wide SSR Markers from Angelica gigas Nakai Using Next Generation Sequencing.

Nakai is an important medicinal herb, widely utilized in Asian countries especially in Korea, Japan, and China. Although it is a vital medicinal herb, the lack of sequencing data and efficient molecular markers has limited the application of a genetic approach for horticultural improvements. Simple sequence repeats (SSRs) are universally accepted molecular markers for population structure study.
