Label-free quantitative proteomic approach to investigate the effect of heat stress on Panax ginseng leaves

ABSTRACT: Ginseng is one of the well-known medicinal plants, exhibiting diverse medicinal effects. Its roots possess anticancer and anti-aging properties and are being used in the medical systems of East Asian countries. Ginseng is grown in low-light and low-temperature conditions and its growth is strongly inhibited at temperatures above 25 ℃. However, the molecular responses of ginseng to heat stress are currently poorly understood, especially at protein level. Therefore, here we utilized a shotgun proteomics approach to investigate the effect of heat stress on ginseng leaves. Total proteins were isolated from control (25 ℃) and ginseng plants exposed to 35 ℃ for 1 and 3 days and subjected to in-solution trypsin digestion. A total of 3,359 ginseng proteins were identified when searched in an in-house developed RNA-seq (PAC-BIO) database.

Label-free Quantitative Proteomic analysis of drought-responsive proteins in Panax ginseng Meyer

Project description:Korean ginseng (Panax ginseng Meyer) has long been cultivated as an important medicinal plant. Drought results from the moderate water loss, which primarily impairs the growth of ginseng and reduction of yield loss. However, basis of biological clues to understanding the accurate mechanisms related to drought stress in proteome level are still elusive. Therefore, we carried out label-free quantitative proteomic analysis using ginseng roots subjected to drought stress which was grown at less than 10% soil moisture for two weeks, compared with normal ginseng which was grown at 25% soil moisture. The acquired proteins were carried out label-free proteomic analysis using LC-MS/MS. This approach led to the identification of total 2,471 proteins, and out of 195 proteins showed significant modulation. Functional classification revealed that proteins related to secondary metabolites, calcium signaling, and photosynthesis were enriched in control sample (cluster_1), while proteins associated with stress responsive, redox, electron transport, and protein synthesis were mainly dominated in cluster_2 (drought stress condition). Taken together, our results provided an overview of the drought-induced proteomic changes in ginseng root, and it is correlated with physiological changes, contributing to reveal potential marker at proteome level in ginseng.

Optimization of Protein Isolation and Label–free Quantitative Proteomic Analysis in Four Different Tissues of Korean Ginseng

Project description:Korean ginseng is one of the most valuable medicinal plants worldwide. Yet, our understanding of ginseng proteomics is largely limited due to difficulties in extraction and resolution of ginseng proteins because of the presence of natural contaminants such as polysaccharides, phenols, and glycosides. Here, we compared four different protein extraction methods, namely, TCA/acetone, TCA/acetone–MeOH/chloroform, Phenol–TCA/acetone, and Phenol–MeOH/chloroform methods. Consequently, the TCA/acetone–MeOH/chloroform method displayed the highest extraction efficiency, thus it was used for the comparative proteome profiling of leaf, root, shoot, and fruit by a label–free quantitative proteomics approach. This approach led to the identification of 2,604 significantly modulated proteins among four tissues. We could pinpoint differential pathways and proteins associated with ginsenoside biosynthesis including the methylerythritol 4–phosphate (MEP) pathway, the mevalonate (MVA) pathway, UDP–glycosyltransferases (UGTs), and oxidoreductases (CYP450s). The current study reports an efficient and reproducible method for the isolation of proteins from a wide range of ginseng tissues and provides a detailed organ–based proteome map and a more comprehensive view of enzymatic alterations in ginsenoside biosynthesis.

Proteomic analysis of Panax ginseng leaves subjected to salinity stress

Project description:Ginseng is an important crop in East Asia due to its medicinal and nutritional benefits originating from ingredients such as the ginsenosides. Numerous researches have been directed to cultivate ginseng with high yield especially targeting its growth and development for protection against abiotic stresses, which are affecting both the yield and quality. Particularly, salinity has been characterized as a major abiotic stressor that affects the annual yield of ginseng. Therefore, to characterize the salt-responsive proteins in the ginseng plant, ginseng leaves were harvested post-treatment with salt in a time-dependent manner. Utilizing a label-free quantitative proteome analysis approach, this study identified a total of 2,484 proteins. Among them, 468 proteins showed a significant modulation in their abundance among ginseng leaf samples at 4 different time points (0, 24, 72, 96 h) following salt stress. Further functional classification revealed that catalase-peroxidase 2, voltage-gated potassium channel subunit beta-2, fructose-1,6-bisphosphatase class 1, and chlorophyll a-b binding protein associated proteins accumulated in response to the salt stress. Of these, glycosyl hydrolase 17 (GH17) showed similar abundance profiles at both the transcript and proteome level. Therefore, for further understanding of GH17 underlying salt stress response mechanism, GH17 overexpressing transgenic Arabidopsis were generated. In response to salt stress, transgenic plants uncovered a tolerance phenotype without compromising plant growth. The proteome alterations in response to salt stress presented here resulted in identifying a protein GH17 with a potential key role in salt-stressed ginseng.

Transcript profiles of the flowering period Panax ginseng C.A. Meyer root and analysis the gene function

Project description:Panax ginseng C.A. Meyer is one of the most popular medicinal herbs. In order to research the genes that related to the flowering period of ginseng, and find out the antifungal proteins and transcription factors that combat various biotic and abiotic stress, a cDNA sample was prepared from the flowering period ginseng root of a five-year-old plant and sequenced using the Illumina sequencing platform. In this study, we produced nearly 40 million sequencing reads. These reads were assembled into 134,045 contigs using Trinity software (mean size: 282 bp). Based on a similarity search with known proteins, we identified 79,307 sequences with a cut-off E-value of 10-5. Assembled sequences were then annotated using gene ontology (GO) terms, clusters of orthologous group (COG) classifications and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways respectively.

An Integrated Biochemical, Proteomics, and Metabolomics Approach for Supporting Medicinal Value of Panax ginseng Fruits (GC-MS assay)

Project description:Panax ginseng roots are well known for their medicinal properties and have been used in Korean and Chinese traditional medicines for 1000s of years. However, the medicinal value of P. ginseng fruits remain poorly characterized. Using gas chromatography-time of flight mass spectrometry (GC-TOF MS), 66 metabolites including amino acids, sugars, organic acids, phenolic acids, phytosterols, tocopherols, and policosanols were identified and quantified. Some of these are well known medicinal compounds and were not previously identified in ginseng. Interestingly, the concentration of almost all metabolites was higher in the Chunpoong and Gumpoong cultivars. Parallel comparison of the four cultivars also revealed higher amounts of the medicinal metabolites in Chunpoong and Gumpoong cultivars. Taken together, our results demonstrate that ginseng fruits are a rich source of medicinal compounds with potential beneficial health effects.

Genome-wide sequencing small RNAs in response to powdery mildew and heat stress in wheat

Project description:To test whether non-coding RNAs play roles in regulating response to powdery mildew infection and heat stress in wheat, by using Solexa high-throughput sequencing and computational analysis and experimental approach we cloned the small RNAs and identified 125 putative long npcRNAs from wheat leaves infected by preponderant physiological strain Erysiphe graminis f. sp. tritici (Egt) or by heat stress treatment. Among long non-coding RNAs, some were precursors of small RNAs such as microRNAs and siRNAs, two long npcRNAs were identified as signal recognition particle (SRP) 7S RNA variants, and three were characterized as U3 snoRNAs. Wheat long npcRNAs showed tissue dependent expression patterns and were responsive to powdery mildew infection and heat stress. Examination non-coding RNAs of 2 near isogenic lines 8866 (Susceptible) and Pm30 (Resistant) in response to powdery milew and two genotypes CK (insensitive) and TAM107 (insensitive) to heat. CK and TAM107 represent the same material in different treatments (no heat stress or 1hour after heat stress).

Hybrid_Poplar_H11-11_Leaves_Local_Stress_Response_DataSet2

Project description:We investigated the transcriptional response of hybrid poplar (Populus trichocarpa x deltoides) leaves to methyl jasmonate treatment over a 24 hour time course. Experiments were conducted using clonal trees under greenhouse conditions at the University of British Columbia. We used the 15.5K poplar cDNA microarray platform previously described by Ralph et al. (Molecular Ecology 2006, 15:1275-1297). Differentially expressed genes were determined using three criteria: fold-change between methyl jasmonate-treated and tween-treated control leaves > 1.5-fold, P value < 0.05 and Q value < 0.05. This study identified > 1,000 differentially expressed genes in response to methyl jasmonate treatment. A factorial hybridization design was chosen to assess gene expression between tween-treated control leaves, and leaves subjected to methyl jasmonate treatment. For each tree, all but the lowest five mature leaves were covered with a light-weight plastic bag and then sprayed with either methyl jasmonate or tween, the solvent control. Leaves were harvested 2, 6 or 24 hours after the initiation of each treatment and total RNA was individually isolated from each tree. For each treatment and time point, equal amounts of total RNA were combined from each of the five biological replicate trees prior to cDNA microarray analysis. A total of 18 hybridizations were performed to directly compare total RNA from methyl jasmonate-treated and tween-treated control leaves at each time point, as well as among methyl jasmonate-treated leaves across time points, with dye balance.

Comparative analysis of maca (Lepidium meyenii) proteome profiles reveals insights into response mechanisms of herbal plants to high-temperature stress

Project description:High-temperature stress (HTS) is one of the main environmental stresses that limit plant growth and crop production in agricultural systems. Maca (Lepidium meyenii) is an important high-altitude herbaceous plant adapted to a wide range of environmental stimuli such as cold, strong wind and UV-B exposure. However, it is an extremely HTS-sensitive plant species. Thus far, there is limited information about gene/protein regulation and signaling pathways related to the heat stress responses in maca. In this study, proteome profiles of maca seedlings exposed to HTS for 12 h were investigated using a tandem mass tag (TMT)-based proteomic approach. In total, 6,966 proteins were identified, of which 300 showed significant alterations in expression following HTS. Bioinformatics analyses indicated that protein processing in endoplasmic reticulum was the most significantly up-regulated metabolic pathway following HTS. Quantitative RT-PCR (qRT-PCR) analysis showed that the expression levels of 19 genes encoding proteins mapped to this pathway were significantly up-regulated under HTS. These results show that protein processing in the endoplasmic reticulum may play a crucial role in the responses of maca to HTS. Our proteomic data can be a good resource for functional proteomics of maca and our results may provide useful insights into the molecular response mechanisms underlying herbal plants to HTS.
