The underlying toxicity mechanism is not well understood. Here, 3-week-old cucumber plants were foliar exposed to different copper concentrations (10, 100, and 500 mg/L) for a final dose of 0.21, 2.1, and 10 mg/plant, using CuSO4 as the Cu ion source for 7 days, three times per day. Metabolomics quantified 149 primary and 79 secondary metabolites. A number of intermediates of the tricarboxylic acid (TCA) cycle were significantly down-regulated 1.4−2.4 fold, indicating a perturbed carbohy- drate metabolism. Ascorbate and aldarate metabolism and shikimate- phenylpropanoid biosynthesis (antioxidant and defense related pathways) were perturbed by excess copper. These metabolic responses occur even at the lowest copper dose considered although no phenotype changes were observed at this dose. High copper dose resulted in a 2-fold increase in phytol, a degradation product of chlorophyll. -

Review Article Umami the Fifth Basic Taste: History of Studies on Receptor Mechanisms and Role As a Food Flavor
Hindawi Publishing Corporation BioMed Research International Volume 2015, Article ID 189402, 10 pages http://dx.doi.org/10.1155/2015/189402 Review Article Umami the Fifth Basic Taste: History of Studies on Receptor Mechanisms and Role as a Food Flavor Kenzo Kurihara Aomori University, Aomori 030-0943, Japan Correspondence should be addressed to Kenzo Kurihara; [email protected] Received 23 March 2015; Accepted 16 June 2015 Academic Editor: Francesco Perticone Copyright © 2015 Kenzo Kurihara.

Three umami substances (glutamate, 5 -inosinate, and 5 -guanylate) were found by Japanese scientists, but umami has not been recognized in Europe and America for a long time. In the late 1900s, umami was internationally recognized as the fifth basic taste based on psychophysical, electrophysiological, and biochemical studies. Three umami receptors (T1R1 + T1R3, mGluR4, and mGluR1) were identified. There is a synergism between glutamate and the5 -nucleotides. Among the above receptors, only T1R1 + T1R3 receptor exhibits the synergism. In rats, the response to a mixture of glutamate and 5 -inosinate is about 1.7 times larger than that to glutamate alone. In human, the response to the mixture is about 8 times larger than that to glutamate alone. Since glutamate and 5 -inosinate are contained in various foods, we taste umami induced by the synergism in daily eating. Hence umami taste induced by the synergism is a main umami taste in human. 1. Introduction and 5 -nucleotides was seen in rodents, but magnitude of the synergism was extremely lower than that in human. -

Mach 1, 38010 San Michele all’Adige (TN), Italy ARTICLE INFO ABSTRACT Chemical compounds studied in this article: Dihydrochalcones are plant secondary metabolites comprising molecules of significant commercial interest as Phloretin (PubChem CID: 4788) antioxidants, antidiabetics, or sweeteners. To date, their heterologous biosynthesis in microorganisms has been Naringenin (PubChem CID: 932) achieved only by precursor feeding or as minor by-products in strains engineered for flavonoid production. Pinocembrin (PubChem CID: 68071) Here, the native ScTSC13 was overexpressed in Saccharomyces cerevisiae to increase its side activity in Phlorizin (PubChem CID: 6072) reducing p-coumaroyl-CoA to p-dihydrocoumaroyl-CoA. De novo production of phloretin, the first committed Nothofagin (PubChem CID: 42607691) dihydrochalcone, was achieved by co-expression of additional relevant pathway enzymes. Naringenin, a major Trilobatin (PubChem CID: 6451798) Naringin dihydrochalcone (PubChem CID: by-product of the initial pathway, was practically eliminated by using a chalcone synthase from barley with 9894584) unexpected substrate specificity. -
