Metabolomes and transcriptomes revealed the saponin distribution in root tissues of and .

Background: and are widely used and well known for their pharmacological effects. As main pharmacological components, saponins have different distribution patterns in the root tissues of plants.

Methods: In this study, the representative ginsenosides were detected and quantified by desorption electrospray ionization mass spectrometry and high-performance liquid chromatography analysis to demonstrate saponin distribution in the root tissues of and , and saponin metabolite profiles were analyzed by metabolomes to obtain the biomarkers of different root tissues.

Integrated metabolomic and transcriptomic analyses revealed the distribution of saponins in .

is famous for its important therapeutic effects. Saponins are bioactive compounds found in different parts and developmental stages of plants. Thus, it is urgently to study saponins distribution in different parts and growth ages of plants.

Rhizospheric microbial communities are driven by at different growth stages and biocontrol bacteria alleviates replanting mortality.

The cultivation of plants is hindered by replanting problems, which may be caused by plant-driven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased, whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages.

Panax ginseng genome examination for ginsenoside biosynthesis.

Ginseng, which contains ginsenosides as bioactive compounds, has been regarded as an important traditional medicine for several millennia. However, the genetic background of ginseng remains poorly understood, partly because of the plant's large and complex genome composition. We report the entire genome sequence of Panax ginseng using next-generation sequencing.

[DNA marker-assisted selection of medicinal plants (Ⅰ) .Breeding research of disease-resistant cultivars of Panax notoginseng].

DNA marker-assisted selection of medicinal plants is based on the DNA polymorphism, selects the DNA sequences related to the phenotypes such as high yields, superior quality, stress-resistance and so on according to the technologies of molecular hybridization, polymerase chain reaction and high-throughput sequencing, and assists the breeding of new cultivars. This study bred the first disease-resistant cultivar of notoginseng "Miaoxiang Kangqi 1" using the technology of DNA marker-assisted selection of medicinal plants and systematic breeding. The disease-resistant cultivar of notoginseng contained 12 special SNPs based on the analysis of Restriction-site Associated DNA Sequencing (RAD-Seq).

[DNA marker-assisted selection of medicinal plants (Ⅲ)Evaluation of disease resistance of "Miaoxiang Kangqi 1" --a new cultivar of Panax notoginseng].

DNA marked-assisted selection of medicinal plants accelerated the breeding and promotion of new cultivars, and guaranteed the healthy development of Chinese medicinal materials industry. The first disease-resistant cultivar of notoginseng, namely "Miaoxiang Kangqi 1", served as the object of study. We evaluated the Kangqi's resistance of seeds, seedlings and root against the pathological bacteria (Fusarum oxysporum) of root rot.

High-throughput sequencing technology reveals that continuous cropping of American ginseng results in changes in the microbial community in arable soil.

Background: American ginseng ( L.) is renowned worldwide for its eutherapeutic effects. The replantation of American ginseng usually fails due to problems associated with continuous cropping.
