Germination and processing are always accompanied by significant changes in the metabolic compositions of rice. In this study, polished rice(rice), brown rice, wet germinated brown rice(WGBR), high temperature and pressure-treated WGBR(WGBR-HTP), and low temperature-treated WGBR(WGBR-T18) were enrolled. An untargeted metabolomics assay isolated 6 122 positive ions and 4 224 negative ions(multiple difference ≥1.2 or ≤0.8333, P<0.05, and VIP≥1) by liquid chromatography-mass spectrum. These identified ions were mainly classified into three categories, including the compounds with biological roles, lipids, and phytochemical compounds. In addition to WGBR-T18 vs. WGBR, massive differential positive and negative ions were revealed between rice of different forms. Flavonoids, fatty acids, carboxylic acids, and organoxygen compounds were the dominant differential metabolites. Based on the Kyoto Encyclopedia of Genes and Genomes(KEGG) database, there 7 metabolic pathways(phenylalanine/tyrosine/tryptophan biosynthesis, histidine metabolism, betalain biosynthesis, C5-branched dibasic acid metabolism, purine metabolism, zeatin biosynthesis, and carbon metabolism) were determined between brown rice and rice. Germination changed the metabolic pathways of porphyrin and chlorophyll, pyrimidine, and purine metabolisms in brown rice. In addition, phosphonate and phosphinate metabolism, and arachidonic acid metabolism were differential metabolic pathways between WGBR-HTP and WGBR-T18. To sum up, there were obvious variations in metabolic compositions of rice, brown rice, WGBR, and WGBR-HTP. The changes of specific metabolites, such as flavonoids contributed to the antioxidant, anti-inflammatory, anti-cancer, and immunomodulatory effects of GBR. HTP may further improve the nutrition and storage of GBR through influencing specific metabolites, such as flavonoids and fatty acids.

作者： Jericha Mill Lingjun Li Department of Chemistry University of Wisconsin-MadisonMadisonWI 53706USA School of Pharmacy University of Wisconsin-MadisonMadisonWI 53705USA

Alzheimer’s disease(AD)is the leading cause of dementia in the aging population,but despite extensive research,there is no consensus on the biological cause of AD.While AD research is dominated by protein/peptide-centric research based on the amyloid hypothesis,a theory that designates dysfunction in beta-amyloid production,accumulation,or disposal as the primary cause of AD,many studies focus on metabolomics as a means of understanding the biological processes behind AD progression.In this review,we discuss mass spectrometry(MS)-based AD metabolomics studies,including sample type and preparation,mass spectrometry data acquisition strategies,and data analysis,as well as biological insights gleaned from these studies,with the hope of informing future AD metabolomic studies.

Geographical indication(GI)rice refers to the rice of specific geographical origin,which tends to have a good taste quality and a high commodity price.Rice is favored for its soft texture and chewiness after cooking.However,GI rice is also plagued by rice fraud.Understanding the reasons for the excellent taste quality of GI rice and identifying its geographical origin can help maintain the stability of the rice market and promote the development of the rice industry.In this study,we determined the taste quality of rice.Untargeted metabolomics based on UHPLC-Q-Exactive-MS was used to identify metabolites in GI and regular rice before and after cooking.Our findings suggested that GI rice showed lower protein and amylose content,resulting in higher starch gelatinization properties and taste quality.This study identified 520 metabolites,among which 142 and 175 were significantly different between GI and regular rice,before and after cooking,respectively.The increased variety of metabolites after cooking was significantly negatively correlated with the taste quality of rice.GI rice was lower in amino acids and lipid metabolite content before and after cooking,which may be the reason for the excellent taste quality.Through linear discriminant analysis,we found that the differential metabolites of rice after cooking were more accurate in discriminating rice from different geographic origins,up to 100%.This work gained new insights into the metabolites of GI rice,which explains its excellent taste quality.The rice metabolites after cooking could be used for more accurate geographical identification of rice.

Tomato is one of the most important vegetable crops in the world and is a model plant used to study the ripening of climacteric fleshy fruit.During the ripening process of tomato fruit,flavor and aroma metabolites,color,texture and plant hormones undergo significant changes.However,low temperatures delayed the ripening process of tomato fruit,inhibiting flavor compounds and ethylene production.metabolomics and transcriptomics analyses of tomato fruit stored under low temperature(LT,5°C)and room temperature(RT,25°C)were carried out to investigate the effects of storage temperature on the physiological changes in tomato fruit after harvest.The results of transcriptomics changes revealed that the differentially expressed genes(DEGs)involved in tomato fruit ripening,including several kinds of transcription factors(TFs)(TCP,WRKY,MYB and bZIP),enzymes involved in cell wall metabolism[beta-galactosidase(β-GAL),pectinesterase(PE)and pectate lyase(PL),cellulose and cellulose synthase(CESA)],enzymes associated with fruit flavor and aroma[acetyltransferase(AT),malic enzyme(ME),lipoxygenase(LOX),aldehyde dehydrogenase(ALDH),alcohol dehydrogenase(ADH)and hexokinase(HK)],genes associated with heat stress protein 70 and genes involved in the production of plant hormones such as Ethylene responsive factor 1(ERF1),Auxin/indoleacetic acids protein(AUX/IAA),gibberellin regulated protein.Based on the above results,we constructed a regulatory network model of the effects of different temperatures during the fruit ripening process.According to the analysis of the metabolomics results,it was found that the contents of many metabolites in tomato fruit were greatly affected by storage temperature,including,organic acids(L-tartaric acid,a-hydroxyisobutyric acid and 4-acetamidobutyric acid),sugars(melezitose,beta-Dlactose,D-sedoheptulose 7-phosphate,2-deoxyribose 1-phosphate and raffinose)and phenols(coniferin,curcumin and feruloylputrescine).This study revealed the effects of storage temperature on postharvest tomato fruit and provided a
