《Miniaturized Photo-Ionization Fourier Deconvolution Ion Mobility Spectrometer for the Detection of Volatile Organic Compoundsã€?was written by Yang, Binwang; Yu, Jianna; Liu, Wen; Jing, Guoxing; Li, Wenshan; Liu, Wenjie. COA of Formula: C8H8O3This research focused onvolatile organic compound photo ionization deconvolution detection; Fourier deconvolution; ion mobility spectrometer; miniaturized drift tube; multiplexing; photoionization. The article conveys some information:

Because of its simplicity, reliability, and sensitivity, the drift tube ion mobility spectrometer (IMS) has been recognized as the equipment of choice for the on-site monitoring and identification of volatile organic compounds (VOCs). However, the performance of handheld IMS is often limited by the size, weight, and drift voltage, which heavily determine the sensitivity and resolving power that is crucial for the detection and identification of VOCs. In this work, we present a low-cost, miniaturized drift tube ion mobility spectrometer incorporated with a miniaturized UV ionization lamp and a relatively low drift voltage. The sensitivity and resolving power are boosted with the implementation of Fourier deconvolution multiplexing compared to the conventional signal averaging data acquisition method. The drift tube provides a high resolving power of up to 52 at a drift length of 41 mm, 10 mm ID dimensions, and a drift voltage of 1.57 kV. Acetone, benzene, di-Me Me phosphonate, Me salicylate, and acetic acid were evaluated in the developed spectrometer and showed satisfactory performance. In the part of experimental materials, we found many familiar compounds, such as Methyl Salicylate(cas: 119-36-8COA of Formula: C8H8O3)

《Overexpression of Citrus reticulata SAMT in Nicotiana tabacum increases MeSA volatilization and decreases Xylella fastidiosa symptomsã€?was published in Planta in 2020. These research results belong to Gomez, Laura M.; Teixeira-Silva, Natalia S.; Caserta, Raquel; Takita, Marco A.; Marques, Marcia O. M.; de Souza, Alessandra A.. Computed Properties of C8H8O3 The article mentions the following:

Main conclusion: Nicotiana tabacum overexpressing CrSAMT from Citrus reticulata increased production of MeSA, which works as an airborne signal in neighboring wild-type plants, inducing PR1 and increasing resistance to the pathogen Xylella fastidiosa. Xylella fastidiosa is one of the major threats to plant health worldwide, affecting yield in many crops. Despite many efforts, the development of highly productive resistant varieties has been challenging. In studying host plant resistance, the S-adenosyl-L-methionine: salicylic acid carboxyl methyltransferase gene (SAMT) from Citrus reticulata, a X. fastidiosa resistant species, was upregulated in response to pathogen infection. SAMT is involved with the catalysis and production of Me salicylate (MeSA), an airborne signal responsible for triggering systemic acquired resistance. Here we used tobacco as a model system and generated transgenic plants overexpressing C. reticulata SAMT (CrSAMT). We performed an in silico structural characterization of CrSAMT and investigated its biotechnol. potential in modulating the immune system in transgenic plants. The increase of MeSA production in transgenic lines was confirmed by gas chromatog. (GC-MS). The transgenic lines showed upregulation of PR1, and their incubation with neighboring wild-type plants activated PR1 expression, indicating that MeSA worked as an airborne signal. In addition, transgenic plants showed significantly fewer symptoms when challenged with X. fastidiosa. Altogether, these data suggest that CrSAMT plays a role in host defense response and can be used in biotechnol. approaches to confer resistance against X. fastidiosa.Methyl Salicylate(cas: 119-36-8Computed Properties of C8H8O3) was used in this study.

A review. In this short review, we attempt to unfold various aspects of excited-state intramol. proton transfer (ESIPT) from the studies that are available up to date. Since Weller’s discovery of ESIPT in salicylic acid (SA) and its derivative Me salicylate (MS), numerous studies have emerged on the topic and it has become an attractive field of research because of its manifold applications. Here, we discuss some critical aspects of ESIPT and tautomerization from the mechanistic viewpoint. We address excitation wavelength dependence, anti-Kasha ESIPT, fast and slow ESIPT, reversibility and irreversibility of ESIPT, hydrogen bonding and geometrical factors, excited-state double proton transfer (ESDPT), concerted and stepwise ESDPT.Methyl Salicylate(cas: 119-36-8Electric Literature of C8H8O3) was used in this study.

Computed Properties of C8H8O3In 2019 ,《Novel insight into the role of withering process in characteristic flavor formation of teas using transcriptome analysis and metabolite profiling》 was published in Food Chemistry. The article was written by Wang, Yu; Zheng, Peng-Cheng; Liu, Pan-Pan; Song, Xiao-Wei; Guo, Fei; Li, Ye-Yun; Ni, De-Jiang; Jiang, Chang-Jun. The article contains the following contents:

Withering is an indispensable process for improving flavors in green, black and white teas during their manufacturing The effects of the withering process on the formation of tea flavors were investigated using transcriptome and metabolite profiling in withered tea leaves. A total of 3268, 23,282 and 25,185 differentially expressed genes (DEGs) were identified at 3 h (68%, water content), 12 h (61%) and 24 h (48%) of the withering process, resp. The DEGs, involved in flavonoid biosynthesis were significantly downregulated, which could be correlated with the reduction of catechins. Enhancement of terpenoids and alpha-linolenic acid metabolism could trigger an increase in the total content and number of volatiles. The increase in free amino acid-content could be related to 261 DEGs. Our study suggests that dehydration stress during withering induced significant changes in the gene transcription and content of the tea flavor compounds, which promoted the special flavors in various teas.

《Identification and analysis of key genes involved in methyl salicylate biosynthesis in different birch species》 was published in PLoS One in 2020. These research results belong to Singewar, Kiran; Moschner, Christian R.; Hartung, Eberhard; Fladung, Matthias. Name: Methyl Salicylate The article mentions the following:

In this study, we performed a comprehensive bioinformatics anal. of two candidate genes mediating MeSA biosynthesis, SALICYLIC ACID METHYLTRANSFERASE (SAMT) and SALICYLIC ACID-BINDING PROTEIN 2 (SABP2), of high (B. lenta, B. alleghaniensis, B. medwediewii, and B. grossa) and low (B. pendula, B. utilis, B. alnoides, and B. nana) MeSA-producing birch species. Phylogenetic analyses of SAMT and SABP2 genes and homologous genes from other plant species confirmed their evolutionary relationships. Multiple sequence alignments of the amino acid revealed the occurrence of important residues for substrate specificity in SAMT and SABP2. The anal. of cis elements in different birches indicated a functional multiplicity of SAMT and SABP2 and provided insights into the regulation of both genes. We successfully developed six prominent single nucleotide substitution markers that were validated with 38 addnl. birch individuals to differentiate high and low MeSA-producing birch species. Relative tissue-specific expression anal. of SAMT in leaf and bark tissue of two high and two low MeSA-synthesizing birches revealed a high expression in the bark of both high MeSA-synthesizing birches. In contrast, SABP2 expression in tissues revealed indifferent levels of expression between species belonging to the two groups. The comparative expression and bioinformatics analyses provided vital information that could be used to apply plant genetic engineering technol. in the mass production of organic MeSA. In addition to this study using Methyl Salicylate, there are many other studies that have used Methyl Salicylate(cas: 119-36-8Name: Methyl Salicylate) was used in this study.

The article was titled 《Use of headspace GC/MS combined with chemometric analysis to identify the geographic origins of black tea》.SDS of cas: 119-36-8 The article contains the following contents:

Some black teas demand high market prices. Black tea samples (306) collected from 10 geog. origins, including China (Guxi, Likou, Jinzipai, Guichi, Dongzhi, Changning, Wuyishan, Shaowu), India (Darjeeling), and Sri Lanka (Kandy), were analyzed using headspace volatilization followed by GC/MS (HS-GC/MS). Forty-eight volatile compounds were identified. The aroma compounds were mainly identified as alcs., aldehydes, ketones, and esters. Anal. of either full-spectrum data or 22 tea compounds shared among the samples with k-Nearest Neighbor (k-NN) and Random Forest (RF) models discriminated all origins at 100% using KNN and 95% with RF using either data set. The discrimination rates using 2 key aroma compounds (linalool and geraniol) by k-NN were 100% for nine origins, with the rate for Guxi area at 89%, because 3 samples were classified to Jinzipai. The findings support the use of HS-GC/MS combined with chemometrics as a tool to identify the origin of black tea.

《Characterization of volatile organic compounds emitted from endophytic Burkholderia cenocepacia ETR-B22 by SPME-GC-MS and their inhibitory activity against various plant fungal pathogens》 was written by Chen, Jian-Hua; Xiang, Wei; Cao, Ke-Xin; Lu, Xuan; Yao, Shao-Chang; Ding, Hung; Huang, Rong-Shao; Li, Liang-Bo. Recommanded Product: Methyl SalicylateThis research focused onvolatile organic endophytic burkholderia cenocepacia antifungal biocontrol; Burkholderia cenocepacia; antifungal activity; bacteria; biocontrol agents; volatile organic compounds. The article conveys some information:

The use of antagonistic microorganisms and their volatile organic compounds (VOCs) to control plant fungal pathogens is an eco-friendly and promising substitute for chem. fungicides. In this work, endophytic bacterium ETR-B22, isolated from the root of Sophora tonkinensis Gagnep., was found to exhibit strong antagonistic activity against 12 fungal pathogens found in agriculture. Strain ETR-B22 was identified as Burkholderia cenocepacia based on 16S rRNA and recA sequences. We evaluated the antifungal activity of VOCs emitted by ETR-B22. The VOCs from strain ETR-B22 also showed broad-spectrum antifungal activity against 12 fungal pathogens. The composition of the volatile profiles was analyzed based on headspace solid phase microextraction (HS-SPME) gas chromatog. coupled to mass spectrometry (GC-MS). Different extraction strategies for the SPME process significantly affected the extraction efficiency of the VOCs. Thirty-two different VOCs were identified. Among the VOC of ETR-B22, di-Me trisulfide, indole, Me anthranilate, Me salicylate, Me benzoate, benzyl propionate, benzyl acetate, 3,5-di-tert-butylphenol, allyl benzyl ether and nonanoic acid showed broad-spectrum antifungal activity, and are key inhibitory compounds produced by strain ETR-B22 against various fungal pathogens. Our results suggest that the endophytic strain ETR-B22 and its VOCs have high potential for use as biol. controls of plant fungal pathogens. The results came from multiple reactions, including the reaction of Methyl Salicylate(cas: 119-36-8Recommanded Product: Methyl Salicylate)

《Methyl salicylate glycosides in some Italian varietal wines》 was written by Carlin, Silvia; Masuero, Domenico; Guella, Graziano; Vrhovsek, Urska; Mattivi, Fulvio. Quality Control of Methyl SalicylateThis research focused onwine methyl salicylate glycoside Italy; Verdicchio wine; gaultherin; glycosides; methyl salicylate; methyl salicylate canthoside A; methyl salicylate gentiobioside; methyl salicylate glucoside; methyl salicylate rutinoside; methyl salicylate sambubioside; violutoside. The article conveys some information:

Glycosides are ubiquitous plant secondary metabolites consisting of a non-sugar component called an aglycon, attached to one or more sugars. One of the most interesting aglycons in grapes and wine is Me salicylate (MeSA), an organic ester naturally produced by many plants, particularly wintergreens. To date, nine different MeSA glycosides from plants have been reported, mainly spread over the genera Gaultheria, Camellia, Polygala, Filipendula, and Passiflora. From a sensorial point of view, MeSA has a balsamic-sweet odor, known as Wintergreen. MeSA was found in Vitis riparia grapes, in Vitis vinifera sp. and in the Frontenac interspecific hybrid. We found that the MeSA glycosides content in Verdicchio wines and in some genetically related varieties (Trebbiano di Soave and Trebbiano di Lugana) was very high. In order to understand which glycosides were present in wine, the methanolic extract of Verdicchio wine was injected into a UPLC-Q-TOF-HDMS and compared to the extracts of different plants rich in such glycosides. Using pure standards, we confirmed the existence of two glycosides in wine: MeSA 2-O-β-D-glucoside and MeSA 2-O-β-D-xylopyranosyl (1-6) β-D-glucopyranoside (gaultherin). For the first time, we also tentatively identified other diglycosides in wine: MeSA 2-O-α-L-arabinopyranosyl (1-6)-β-D-glucopyranoside (violutoside) and MeSA 2-O-β-D-apiofuranosyl (1-6)-β-D-glucopyranoside (canthoside A), MeSA 2-O-β-D-glucopyranosyl (1-6)-O-β-D-glucopyranoside (gentiobioside) and MeSA 2-O-α-L-rhamnopyranosyl (1-6)-β-D-glucopyranoside (rutinoside). Some of these glycosides have been isolated from Gaultheria procumbens leaves by preparative liquid chromatog. and structurally annotated by 1H- and 13C-NMR anal. Two of the peaks isolated from Gaultheria procumbens leaves, namely MeSA sambubioside and MeSA sophoroside, were herein observed for the first time. Six MeSA glycosides were quantified in 64 Italian white wines, highlighting the peculiar content and pattern in Verdicchio wines and related cultivars. The total concentration in bound and free MeSA in Verdicchio wines varied in the range of 456-9796μg/L and 5.5-143μg/L, resp., while in the other wines the bound and free MeSA was below 363μg/L and 12μg/L, resp. As this compound’s olfactory threshold is between 50 and 100μg/L, our data support the hypothesis that Me salicylate can contribute to the balsamic scent, especially in old Verdicchio wines.

In 2019,Plant Physiology included an article by Chen, Lu; Wang, Wen-Shuai; Wang, Ting; Meng, Xia-Fei; Chen, Ting-Ting; Huang, Xu-Xu; Li, Yan-Jie; Hou, Bing-Kai. Computed Properties of C8H8O3. The article was titled 《Methyl salicylate glucosylation regulates plant defense signaling and systemic acquired resistance》. The information in the text is summarized as follows:

Here, we characterized a uridine diphosphate-glycosyltransferase, UGT71C3, in Arabidopsis (Arabidopsis thaliana), which was induced mainly in leaf tissue by pathogens including Pst DC3000/avrRpt2 (Pseudomonas syringae pv tomato strain DC3000 expressing avrRpt2). Biochem. anal. indicated that UGT71C3 exhibited strong enzymic activity toward MeSA to form MeSA glucosides in vitro and in vivo. After primary pathogen infection by Pst DC3000/avrRpt2, ugt71c3 knockout mutants exhibited more powerful systemic resistance to secondary pathogen infection than that of wild-type plants, whereas systemic resistance in UGT71C3 overexpression lines was compromised. In agreement, after primary infection of local leaves, ugt71c3 knockout mutants accumulated significantly more systemic MeSA and SA than that in wild-type plants. whereas UGT71C3 overexpression lines accumulated less. Our results suggest that MeSA glucosylation by UGT71C3 facilitates neg. regulation of the SAR response by modulating homeostasis of MeSA and SA. This study unveils further SAR regulation mechanisms and highlights the role of glucosylation of MeSA and potentially other systemic signals in neg. modulating plant systemic defense.
