Proteomic analysis of cucumber (Cucumis sativus) fruit peel in response to pre-storage cold acclimation

ABSTRACT: To distinguish PsCA-responsive proteins, total proteins extracted from the non-acclimated fruit, the fruit exposed to 3 d of cold acclimation, the control fruit stored at 5oC for 12 d and the fruit exposed to 3d of PsCA treatment followed by 9 d of cold storage were separated by 2-DE, respectively. More than 750 protein spots were detected using PDQuest Advanced 2-D Gel Analysis software (Version 8.0) following the 2-DE gel analysis. Of the 750 spots, 58 that displayed significant and reproducible changes in abundance were isolated, and 56 spots were successfully characterized using MS/MS coupled with database searching, which matched 51 proteins. 38 proteins have scores greater than threshold scores of 61(P < 0.05) and they are regarded as the significant differentially- accumulated proteins (SDAPs).

Proteomic Analysis of Differentially Accumulated Proteins in Cucumber (<i>Cucumis sativus</i>) Fruit Peel in Response to Pre-storage Cold Acclimation.

Wang Bin B Shen Fei F Zhu Shijiang S

Frontiers in plant science 20180118

Harvested fruits are still living organs and respond to environmental stimuli. Low temperature storage is effective in extending life of harvested fruit, but it may also cause chilling injury. Cold acclimation has been shown to induce chilling tolerance in plants, but what proteomic changes caused by cold acclimation are related to defense against chilling stress remains largely unclear. Here, 3 d of pre-storage cold acclimation (PsCA) at 10°C reduced chilling injury and secondary disease severi ...[more]

Podophyllum hexandrum Royle MS/MS

Project description:In order to study the molecular mechanisms of cold-adaption and PPT accumulation to understand why P. hexandrum adapts to chilling temperature, the differentially expressed proteins (DAPs) of P. hexandrum seedling exposed to chilling temperatures (4 and 10°C, 22°C as control) were conducted by using 2-DE in combination with MALDI-TOF-MS, a total of 35 DAP spots were detected and identified. Interestingly, 14 of the 35 DAPs played key roles in PPT biosynthesis, and 21 proteins participated in growth and development. These protein spots were classified into 7 functional categories, including PPT biosynthesis, primary metabolism, transcription and protein synthesis, cell growth/division, defense, transport, and energy. The present data would be useful in better understanding the molecular basis of chilling temperature response in P. hexandrum.

Gene expression of Drosophila melanogaster in response to multiple cold exposures

Project description:In the field, insects suffer multiple cold exposures during winter. When exposed to repeated low temperatures, Drosophila melanogaster females showed an increase in survival, but a reduction in reproduction. In this study, the microarrays were used to analyze the gene expression of female D. melanogaster after multiple, single sustained (or single prolonged) and single short cold treatments, which exposed the flies at 0 M-0C for repeated 2 h, single 10 h and single 2 h respectively. Candidate genes that were involved in 6 h recovery from different types of cold exposures were identified. After repeated cold exposures, candidates particularly included genes involved in muscle protein and muscle activity. Stress-related genes, Turandot A, Turandot C, and Turandot M were up-regulated in response to multiple cold exposures, and improve the cold survival in female D. melanogaster. This work also suggested a strong relationship between cold exposure and the immune system. I suggest that in fruit flies, chilling injuries after cold exposure may induce immune responses and contribute to recovery from cold.

KIWIFRUIT PROTEIN CHANGES DURING POSTHARVEST COLD STORAGE

Project description:We report on the kiwifruit postharvest phase through an approach consisting of 2D-DIGE/nanoLC-ESI-LIT-MS/MS-based proteomic measurements. Kiwifruit samples stored under conventional, cold-based postharvest conditions were sampled at four stages (from fruit harvest to pre-commercialization) and analyzed in comparison protein content. Proteomics showed that proteins associated with disease/defense, energy, protein destination/storage, cell structure and metabolism functions were affected at precise fruit postharvest times. By lining up kiwifruit postharvest processing to a proteomic depiction, this study integrates previous observations on protein content in postharvest pomes treated with specific chemical additives, and provides a reference framework for further studies on the optimization of fruit storage before its commercialization.

Comparative proteome analysis of a clonal virulent and attenuated Histomonas meleagridis strain.

Project description:The current study aimed to detect and identify significant differentially expressed proteins between a virulent and an attenuated Histomonas meleagridis strain which was in vitro co-cultivated with Escherichia coli DH5α. Two-dimensional gel electrophoresis (2-DE) was used for proteome visualization , gel image software for computational detection of significantly up-regulated protein spots and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry (MALDI-TOF/TOF MS) for protein identification. The statistical analysis fulfilling two criteria (> or = 3-fold up-regulation and P<0.05) detected 119 differentially expressed protein spots out of which 62 spots were located in gels of the virulent strain and 57 spots in gels of the attenuated strain. The mass spectrometric analysis of 32 spots, up-regulated in gels of the virulent strain, showed that they are of H. meleagridis origin. As opposed to this, the mass spectrometric analysis of 49 protein spots , up-regulated in the gels of the attenuated strain , identified 32 spots as specific to the protozoan. Additionally, the analysis identified a number of E. coli DH5α proteins which were detected as differentially expressed by the computational gel image and statistical analysis.

Copper stress-induced changes in leaf soluble proteome of Cu-sensitive and tolerant Agrostis capillaris L. populations

Project description:Changes in leaf soluble proteome were explored in 3-month-old plants of Cu-tolerant (metallicolous, M) and sensitive (non-metallicolous, NM) Agrostis capillaris L. populations exposed to increasing Cu concentrations (1-50 µM). Aims of the study were to investigate (1) differential protein expression in NM and M leaves under increasing Cu exposure, and (2) molecular mechanisms underlying higher Cu tolerance in M plants. Plants were cultivated on perlite (CuSO4 spiked-nutrient solution); fresh leaf aliquots were frozen in liquid nitrogen. Soluble leaf proteins were extracted by the trichloroacetic acid/acetone procedure, and separated with 2-DE (linear 4-7 pH gradient). Analysis of CCB-stained gels (PDQuest) reproducibly detected 214 spots, of which 107 were analyzed using LC-MS/MS.

Na2CO3-responsive proteins in Puccinellia tenuiflora leaves

Project description:Puccinellia tenuiflora is a monocotyledonous halophyte species belonging to the Gramineae. It has strong ability for surviving in the extreme saline-alkali soil (pH range of 9-10). In the present study, proteins from leaves under various Na2CO3 treatments were separated and visualized on Coomassie Brilliant Blue-stained two-dimensional gel electrophoresis (2-DE) gels. After gel image analysis on the base of the calculated average vol% values of each protein spot, 174 protein spots were detected as abundance changed protein spots (1.5-fold changes, p < 0.05). Among them, 104 protein spots were identified using MALDI-TOF MS/MS and Mascot database searching. Thus the 104 protein identities represented 80 unique proteins were taken as Na2CO3-responsive proteins in leaves. After integrative analysis by BLAST alignment, Kyoto Encyclopedia of Genes and Genomes, and referring information from related literature, they were classified into 10 functional categories, including photosynthesis, carbohydrate and energy metabolism, other metabolisms, stress and defense, membrane and transport, signaling, protein synthesis, folding, and turnover, cell wall mechanism, cell cycle, and miscellaneous or unknown.

Alterations in kernel proteome after infection with Fusarium culmorum in two triticale cultivars with contrasting resistance to Fusarium head blight

Project description:Triticale was used as a model to recognize new components of molecular mechanism of resistance to Fusarium head blight (FHB) in cereals. Fusarium-damaged kernels of two lines distinct in levels of resistance to FHB were applied into a proteome profiling using two-dimensional gel electrophoresis (2-DE) to create protein maps and mass spectrometry to identify the proteins differentially accumulated between the analyzed lines. The 2-DE analysis indicated a total of 23 spots with clear differences in a protein content between the more resistant and more susceptible triticale lines after infection with F. culmorum. A majority of the proteins were involved in a cell carbohydrate metabolism, stressing the importance of this protein group in a plant response to Fusarium infection. The increased accumulation levels of different isoforms of plant beta-amylase were observed for a more susceptible triticale line after inoculation. The more resistant line was characterized by a higher abundance of alpha-amylase inhibitor CM2 subunit.

Effect of 1-methylcyclopropene (1-MCP) and ozone (Ο 3 ) post-harvest treatments on the proteomic profiling of Granny Smith apple peel (Malus x domestica Borkh) after cold storage

Project description:Superficial scald is a major physiological disorder in apple fruit that is induced by cold storage and is mainly expressed as brown necrotic patches on peel tissue. However, a global view of the gene-protein-metabolite interactome underlying scald prevention/sensitivity is currently missing. Herein, we have found for the first time that cold storage in an atmosphere enriched with ozone (O3) induced scald symptoms in ‘Granny Smith’ apple fruits during subsequent ripening at room temperature. In contrast, treatment with the ethylene perception inhibitor 1-methylcyclopropene (1-MCP) reversed this O3-induced scald effect. Amino acids, including branched-chain amino acids, were the most strongly induced metabolites in peel tissue of 1-MCP treated fruits. Proteins involved in oxidative stress and protein trafficking were differentially accumulated prior to and during scald development. Genes involved in photosynthesis, flavonoid biosynthesis and ethylene signaling displayed significant alterations in response to 1-MCP and O3. Analysis of regulatory module networks identified putative transcription factors (TFs) that could be involved in scald. Subsequently, a transcriptional network of the genes-proteins-metabolites and the connected TFs was constructed. This approach enabled identification of several genes co-regulated by TFs, notably encoding glutathione S-transferase (GST) protein(s) with distinct signatures following 1-MCP and O3 treatments. Overall, this study is an important contribution to future functional studies and breeding programs for this fruit, aiding to the development of improved apple cultivars to superficial scald.
