Jakobs, Ruth; Schweiger, Rabea; Mueller, Caroline published the artcile< Aphid infestation leads to plant part-specific changes in phloem sap chemistry, which may indicate niche construction>, Electric Literature of 87-73-0, the main research area is Tanacetum Macrosiphoniella Uroleucon phloem sap chem metabolomics niche construction; aphid; metabolomics; niche conformance; niche construction; phloem sap chemistry.

Phloem sap quality can differ between and within plants, and affect the performance of aphids. In turn, aphid infestation may change the chem. composition and nutritional value of phloem sap. However, the effects of different aphid species on the overall phloem sap composition of distinct parts within plant individuals in relation to aphid performance remain unclear. To test the specificity of plant responses to aphids, we used two chemotypes of Tanacetum vulgare plants and placed the monophagous aphids Macrosiphoniella tanacetaria and Uroleucon tanaceti on different plant parts (stems close to the inflorescence, young and old leaves). Aphid population growth was determined and sugars, organic acids, amino acids and metabolic fingerprints of phloem exudates were analyzed. Macrosiphoniella tanacetaria performed best on stems, whereas U. tanaceti performed best on old leaves, indicating differences in niche conformance. Aphid infestation led to distinct changes in the phloem exudate composition of distinct metabolite classes, differing particularly between plant parts but less between chemotypes. In summary, plant responses to aphids are highly specific for the chemotype, plant part, metabolite class and aphid species. These changes may indicate that aphids construct their own niche, optimizing the food quality on the plant parts they prefer.

Li, Linhan; Zhou, Ting; Zhong, Linyu; Zhou, Qian; Gu, Gang; Hu, Mengjun; Chen, Fengping; Lin, Sheng published the artcile< Bioremediation of quinclorac injury on tobacco by a rhizosphere bacterium>, Application In Synthesis of 87-73-0, the main research area is rhizosphere bacterium tobacco quinclorac injury bioremediation; Bioremediation; Herbicide; Klebsiella variicola; Plant growth-promoting bacterium; Tobacco.

The presence of herbicides residues in soil represents a serious problem for agriculture. Quinclorac is a common herbicide applied in rice field, but its residue can cause abnormal growth in successive crop of tobacco in Southern China. Remediation by microorganisms is considered to be an environmentally friendly method to remove such pollutants injury. The aims of this study were to obtain quinclorac remediation isolates and to investigate the possible mechanism(s) of remediation. Six bacterial isolates were obtained from rhizosphere of rice-tobacco rotation fields, and were found to be capable of degrading quinclorac on a mineral salt medium (MSM), with degradation efficiency ranging from 2.1 to 23.7%. Among these isolates, J5 had the highest degradation efficiency, and was identified as Klebsiella variicola based on phylogenetic anal. and a metabolic profile generating by Biolog GEN III system. Bioremediation of quinclorac injury was confirmed using pot assays with tobacco, in which J5 reversed the detrimental effect of quinclorac on leaf area, leaf number, and plant height. The J5 isolate also seemed to promote plant growth, in terms of tobacco seedling growth and seed germination, which were 2.2 times and 1.6 times higher compared to untreated control, resp. The mechanisms of plant growth promoting (PGP) traits were found to involve nitrogen-fixing, indole-3-acetic acid (IAA) production, and phosphate solubilization ability. In addition, proteomic anal. and relative quant. PCR revealed an elevated level of 4-hydroxyphenylacetate 3-monooxygenase (HPMO) in quinclorac-treated J5, suggesting that this enzyme may play an important role in quinclorac remediation. This study showed that the J5 isolate could be exploited to not only assist in soil remediation due to quinclorac residue issues but also promote tobacco growth.

Du, Wenchao; Liu, Xing; Zhao, Lijuan; Xu, Yanwen; Yin, Ying; Wu, Jichun; Ji, Rong; Sun, Yuanyuan; Guo, Hongyan published the artcile< Response of cucumber (Cucumis sativus) to perfluorooctanoic acid in photosynthesis and metabolomics>, Synthetic Route of 87-73-0, the main research area is Cucumis perfluorooctanoic acid photosynthesis metabolome; Amino acid; Bioaccumulation; Chlorophyll; PFOA; Phenolic.

A mechanistic understanding of perfluorooctanoic acid (PFOA) toxicity to plants is essential for future risk assessment of PFOA in agricultural soil. In this study, soil-grown cucumber (Cucumis sativus) was exposed to 0, 0.2, and 5 mg/kg of PFOA for 60 days. At harvest, contaminant accumulation, cucumber biomass, photosynthesis profiles and metabolites were measured. Results showed that PFOA depressed cucumber biomass and accumulated highest in leaves. Photosynthesis anal. revealed that PFOA at both doses reduced the chlorophyll contents and net photosynthesis rate of cucumber leaves. Gas chromatog.-mass spectrometry-based non-targeted metabolomics revealed that PFOA induced metabolic reprogramming in cucumber leaves, including up-regulation of phenols (at 0.2 and 5 mg/kg) and down-regulation of amino acids (at 5 mg/kg), indicating disrupted nitrogen and carbon metabolism Results revealed how PFOA represses plant growth by down-regulating photosynthetic pigments and disturbing the metabolism of carbohydroxides, phenols and amino acids. These findings provide valuable information for understanding the mol. mechanisms involved in plant responses to PFOA-induced stress.

Shi, Honghui; Yang, Endian; Yang, Heyue; Huang, Xiaoling; Zheng, Mengxia; Chen, Xiaoyang; Zhang, Junjie published the artcile< Dynamic changes in the chemical composition and metabolite profiles of drumstick (Moringa oleifera Lam.) leaf flour during fermentation>, Product Details of C6H10O8, the main research area is Moringa Aspergillus Candida Bacillus carbohydrate amino acids myoinositol oligosaccharides.

Solid-state fermentation (SSF) using mixed strains can increase the nutritional value and antioxidant content of Moringa oliefera Lam. leaf flour (MLF). However, little is known about the chem. composition and metabolite profiles of MLF during the fermentation process. In this work, mixed strains of Aspergillus Niger, Candida utilis and Bacillus subtilis were inoculated into MLF for SSF. The MLF′s contents of crude protein (CP), crude fiber (CF), water soluble carbohydrate (WSC), reducing sugar, tannin and phytic acid all changed significantly as fermentation proceeded. A metabolomic anal. was performed using GC-TOF-MS, resulting in the identification of 347 metabolites. Fermentation with mixed strains significantly affected levels of amino acids, sugars, and organic acids; concentrations of most amino acids, oligosaccharides, organic acids, nucleosides, γ-aminobutyric acid (GABA), and myo-inositol were higher after 3 d of SSF than at the start. Addnl., several intermediate metabolites were detected in 3 d fermented MLF. The mixed microorganisms′ metabolic activity thus seems to peak after 3 d of fermentation under the tested conditions. These results provide new insights into the changes in the chem. composition and metabolite content of MLF during SSF and reveal possibilities for producing valuable compounds via this process.

An aerobic, Gram-stain-neg. ovoid, designated as strain A21T, was isolated using the dilution-to-extinction method from a soil sample taken from Rambla Salada, an athalassohaline habitat located in Murcia (south-eastern Spain). Strain A21T is nonmotile, has a respiratory metabolism and grows at NaCl concentrations within the range 0.5-15% (w/v) [optimum, 5% (w/v)], at 5-35°C (optimum, 28°C) and at pH 6-8 (optimum, pH 7.0). This strain is pos. for catalase activity, oxidase activity and nitrate reduction The 16S rRNA gene sequence indicates that it belongs to the genus Roseovarius in the class Alphaproteobacteria. The most closely related species are Roseovarius pacificus and Roseovarius halotolerans to which the strain A21T shows 16S rRNA gene sequence similarity values of 98.06 and 97.7%, resp. The average nucleotide identity in blast and digital DNA-DNA hybridization values between strain A21T and R. pacificus LMG 24575T are 76.8 and 21%, resp. The DNA G+C content based on the genome is 61.28mol%. The major fatty acids (>5% of the total fatty acids) of strain A21T are C18:1ω7c/C18:1ω and C18:1. The only detected isoprenoid quinone in strain A21T is ubiquinone 10 (Q-10). The polar lipid profile contains phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and three unidentified polar lipids. Based on the phylogenetic, genotypic, phenotypic and chemotaxonomic data, the strain represents a novel species of the genus Roseovarius, for which the name Roseovarius bejariae sp. nov. is proposed. Strain A21T (=CECT 9817T =LMG 31311T) is the type strain.

Huanglongbing (HLB) is one of the most destructive diseases in citrus worldwide. Unfortunately, HLB has no cure and management relies on insecticides to reduce populations of the vector, Diaphorina citri Kuwayama (Hemiptera: Liviidae). We propose an attract-and-kill strategy using a trap crop as an alternative to vector control to reduce transmission of the pathogen, ‘Candidatus Liberibacter asiaticus’. We evaluated vector response to phytoene desaturase-silenced citrus trees using virus-induced gene silencing technol. Citrus tristeza virus (CTV) was used to produce a phytoene desaturase-silenced citrus (CTV-tPDS) that expresses visual, olfactory, and gustatory cues to attract D. citri. We found that D. citri were more attracted to CTV-tPDS plants with noticeably better fecundity and overall population fitness than on control plants. Moreover, rearing D. citri on CTV-tPDS plants significantly increased their survival probability compared with those reared on control plants. CTV-tPDS plants possessed reduced content of both carotenoid and chlorophyll pigments resulting in a consistent photobleached phenotype on citrus leaves which provided a sufficient close-range visual attractant to stimulate D. citri landing. Addnl., CTV-tPDS plants exhibited an enriched profile of volatile organic compounds (VOCs), which offered adequate olfactory cues to attract psyllid from long-range. Finally, CTV-tPDS plants exhibited an enriched metabolite content of phloem sap and leaves which offered appropriate gustatory cues that influenced probing/feeding behavior. We believe that introducing CTV-tPDS plants (as a trap crop) to D. citri-infested orchards will attract and congregate psyllids to facilitate their removal from the target crop with insecticides or by other means. This new strategy could be deployed relatively quickly and economically to HLB-impacted citrus industries. Moreover, it is an eco-friendly strategy because it should partially reduce the input of chem. insecticides ameliorating the indirect cost of HLB infection.

Renal cell carcinoma (RCC) is a malignant tumor that currently lacks clin. useful biomarkers indicative of early diagnosis or disease status. RCC has commonly been diagnosed based on imaging results. Metabolomics offers a potential technol. for discovering biomarkers and therapeutic targets by comprehensive screening of metabolites from patients with various cancers. We aimed to identify metabolites associated with early diagnosis and clinicopathol. factors in RCC using global metabolomics (G-Met). Tumor and nontumor tissues were sampled from 20 cases of surgically resected clear cell RCC. G-Met was performed by liquid chromatog. mass spectrometry and important metabolites specific to RCC were analyzed by multivariate statistical anal. for cancer diagnostic ability based on area under the curve (AUC) and clinicopathol. factors (tumor volume, pathol. T stage, Fuhrman grade, presence of coagulation necrosis and distant metastasis). We identified 58 metabolites showing significantly increased levels in tumor tissues, 34 of which showed potential early diagnostic ability (AUC >0.8), but 24 did not discriminate between tumor and nontumor tissues (AUC ≤0.8). We recognized 6 pathways from 9 metabolites with AUC >0.8 and 7 pathways from 10 metabolites with AUC ≤0.8 about malignant status. Clinicopathol. factors involving malignant status correlated significantly with metabolites showing AUC ≤0.8 (p = 0.0279). The tricarboxylic acid cycle (TCA) cycle, TCA cycle intermediates, nucleotide sugar pathway and inositol pathway were characteristic pathways for the malignant status of RCC. In conclusion, our study found that metabolites and their pathways allowed discrimination between early diagnosis and malignant status in RCC according to our G-Met protocol.

Metabolites can mediate species interactions and the assembly of microbial communities. However, how these chems. relate to the assembly processes and co-occurrence patterns of diazotrophic assemblages in root-associated soils remains largely unknown. Here, we examined the diversity and assembly of diazotrophic communities and further deciphered their links with metabolites on Tibetan Plateau. We found that the distribution of sugars and organic acids in the root-associated soils was significantly correlated with the richness of diazotrophs. The presence of these two soil metabolites explains the variability in diazotrophic community compositions The differential concentrations of these metabolites were significantly linked with the distinctive abundances of diazotrophic taxa in same land types dominated by different plants or dissimilar soils by same plants. The assembly of diazotrophic communities is subject to deterministic ecol. processes, which are widely modulated by the variety and amount of sugars and organic acids. Organic acids, for instance, 3-(4-hydroxyphenyl)propionic acid and citric acid, were effective predictors of the characteristics of diazotrophic assemblages across desert habitats. Diazotrophic co-occurrence networks tended to be more complex and connected within different land types covered by the same plant species. The concentrations of multiple sugars and organic acids were coupled significantly with the distribution of keystone species, such as Azotobacter, Azospirillum, Bradyrhizobium, and Mesorhizobium, in the co-occurrence network. These findings provide new insights into the assembly mechanisms of root-associated diazotrophic communities across the desert ecosystems of the Tibetan Plateau.

As a useful chem., furan can be produced from bio-based chems., such as furfural and furoic acid (FA). There were few reports on the preparation of furan from bio-based C6 aldaric acids. Herein, a new method was developed to produce furan from D-glucaric acid (GA) without transition metals, and nearly 80% yield of furan was produced in the water/toluene biphasic system with SnCl4 at 200°C in 2 h. The 3-Hydroxy-2-pyrone (3-HP) and FA were proved to be the key intermediates in the formation of furan from GA, and the reaction pathway was proposed to be GA→ 3-HP→ FA→ furan based on the kinetic study, model substrate reaction, and isotope labeling experiments SnCl4 gave the highest furan yield among the common acid catalysts, and the contrast experiments suggested that H+, Cl- and Sn4+ all have promoting effect on GA conversion to furan. This method was also applicable with other C6 aldaric acids.
