Comparative transcriptome analysis provides novel insights into the seed germination of Panax japonicus, an endangered species in China.

Panax japonicus, an endangered species in China, is usually used as a traditional medicine with functions of hemostasis, pain relief, and detoxify. However, the seeds of P. japonicus are hard to germinate in natural conditions, and the molecular events and systematic changes occurring in seed germination are still largely unknown.

Combined transcriptome and metabolome analyses reveal the effects of selenium on the growth and quality of .

Thunb () is an important medicinal and edible plant with outstanding functionality for selenium (Se) biofortification. However, the molecular response of to exogenous Se has not been fully elucidated. In this study, the effects of different levels of Se on growth and quality were explored by transcriptome, metabolome and biochemical analyses.

TMT-Based Proteomic Analysis of Continuous Cropping Response in Oliv.

The growth and development of , an important herb used in Chinese traditional medicine, have been seriously affected by continuous cropping obstacles. Therefore, understanding the molecular responses of to continuous cropping is imperative to improve its resistance to continuous cropping obstacles. Here, physiological and biochemical results showed that the levels of chlorophyll and malonaldehyde (MDA) were higher in the continuous cropping (LZ) group compared with those of the non-continuous cropping (FLZ) group, while superoxide dismutase (SOD) content was lower in the LZ group than in the FLZ group.

Transcriptomic Analysis Provides Novel Insights into the Heat Stress-Induced Response in .

Oliv () is a valuable traditional Chinese medicinal herb with tremendous health benefits. However, the growth and development of are seriously affected by high temperatures. Therefore, understanding the molecular responses of to high-temperature stress is imperative to improve its thermotolerance.

Transcriptome and metabolome analyses reveal novel insights into the seed germination of Michelia chapensis, an endangered species in China.

Michelia chapensis Dandy, a well-known medicinal woody plant endemic to China, is endangered and seriously constricted by seed dormancy-induced low-regeneration in natural conditions. Cold stratification can effectively reduce seed dormancy and promote the seed germination of M. chapensis.

Transcriptome analysis provides novel insights into the soil amendments induced response in continuously cropped .

Oliv () is an important Chinese traditional medicinal plant with various health benefits. However, the growth of are seriously affected by continuous cropping, which led to the decrease of the yield and quality. A field experiment was conducted to learn the effects of soil amendments on the growth of under continuous cropping condition, and the biological events which occurred at molecular level were investigated.

Effects of foliar selenium application on growth and rhizospheric soil micro-ecological environment of Koidz.

(), a famous medicinal herb in China, is widely cultivated and consumed in China with various beneficial effects. Numerous studies have shown that selenium (Se) plays an important role in promoting plant growth, although Se has not been considered an essential element for higher plants. The objectives of this research were to determine the effects of foliar Se application (0, 2.

Transcriptomic analysis of short-term heat stress response in Pinellia ternata provided novel insights into the improved thermotolerance by spermidine and melatonin.

Heat stress has been a major environmental factor limiting the growth and development of Pinellia ternata which is an important Chinese traditional medicine. It has been reported that spermidine (SPD) and melatonin (MLT) play pivotal roles in modulating heat stress response (HSR). However, the roles of SPD and MLT in HSR of P.

Transcriptome analysis reveals novel insights into the continuous cropping induced response in Codonopsis tangshen, a medicinal herb.

Water management impacts the soil microbial communities and total arsenic and methylated arsenicals in rice grains.

The bioavailability of the metalloid arsenic (As) in paddy soil is controlled by microbial cycling of As and other elements such as iron (Fe) and sulfur (S), which are strongly influenced by water management in paddy fields. In this study, we evaluated how water management affects As bioavailability by growing rice plants in a geogenic As-contaminated soil. We determined As speciation in soil porewater and the diversity of the associated microbial community.

Nitrate Stimulates Anaerobic Microbial Arsenite Oxidation in Paddy Soils.

Arsenic (As) bioavailability to rice plants is elevated in flooded paddy soils due to reductive mobilization of arsenite [As(III)]. However, some microorganisms are able to mediate anaerobic As(III) oxidation by coupling to nitrate reduction, thus attenuating As mobility. In this study, we investigated the impact of nitrate additions on As species dynamics in the porewater of four As-contaminated paddy soils.

Anaerobic arsenite oxidation by an autotrophic arsenite-oxidizing bacterium from an arsenic-contaminated paddy soil.

Microbe-mediated arsenic (As) redox reactions play an important role in the biogeochemical cycling of As. Reduction of arsenate [As(V)] generally leads to As mobilization in paddy soils and increased As availability to rice plants, whereas oxidation of arsenite [As(III)] results in As immobilization. A novel chemoautotrophic As(III)-oxidizing bacterium, designated strain SY, was isolated from an As-contaminated paddy soil.
