Abstract Melatonin ( N ‐acetyl‐5‐methoxytryptamine) was detected by a modified HPLC method and ELISA tests in extracts of eight different Vitis vinifera cultivars, namely Nebbiolo, Croatina, Sangiovese, Merlot, Marzemino, Cabernet Franc, Sauvignon Barbera. Its concentration varied greatly among the being highest Nebbiolo (0.965 ng g −1 ) Croatina (0. 870 ). Field treatments grapevine with plant defence activator benzothiadiazole, improved melatonin content berry skin extracts, indicating...
Basil (Ocimum basilicum L.) is a culinary, medicinal, and ornamental plant appreciated for its antioxidant properties, mainly attributed to high content of rosmarinic acid. This species also includes purple varieties, characterized by the accumulation anthocyanins in leaves flowers. In this work, we compared main morphological characteristics, capacity chemical composition leaves, flowers, corollas green ('Italiano Classico') ('Red Rubin' 'Dark Opal') basil varieties. The LC-ESI-MS/MS...
To acquire information on the relationships between structural maturation of proteins in endoplasmic reticulum (ER) and their transport along secretory pathway, we have analyzed destiny an assembly-defective form trimeric vacuolar storage glycoprotein phaseolin. In leaves transgenic tobacco, where assembly-competent phaseolin is correctly targeted to vacuole, defective remains located ER or a closely related compartment it represents major ligand chaperone BiP. Defective maintained...
Pre-harvest multiple treatments of grapevine (cv. Merlot) with the plant activator benzothiadiazole (BTH, 0.3 mM) enhanced trans-resveratrol content in berries by about 40%. An even more striking effect was observed on anthocyanin synthesis, particularly malvidine 3-glucoside, 3-(6-O-acetyl)glucoside and 3-(6-O-p-coumaroyl)glucoside, whose amounts were than doubled. These data obtained a novel time-saving HPLC method, set up for simultaneous detection stilbenes anthocyanins, using an...
Phaseolin, one of the major legume proteins for human nutrition, is a trimeric glycoprotein 7S class that accumulates in protein storage vacuoles common bean. Phaseolin cotranslationally introduced into lumen endoplasmic reticulum; from there, it transported through Golgi complex to vacuoles. also vacuole vegetative tissues transgenic plants. By transient and permanent expression tobacco leaf cells, we show here vacuolar sorting phaseolin saturable saturation leads Golgi-mediated secretion...
Grapevine ( Vitis vinifera) products, grape and juice, represent a valuable source of bioactive phytochemicals, synthesized by three secondary metabolic pathways (phenylpropanoid, isoprenoid alkaloid biosynthetic routes) stored in different plant tissues. In the last decades, compelling evidence suggested that regular consumption these products may contribute to reducing incidence chronic illnesses, such as cancer, cardiovascular diseases, ischemic stroke, neurodegenerative disorders aging,...
Melatonin has been reported in a variety of food plants and, consequently, number plant-derived foodstuffs. In grapevine (Vitis vinifera L.) products, it was found berry exocarp (skin) different cultivars and monovarietal wines. Herein, we assessed, by means mass spectrometry, the occurrence melatonin all tissues (skin, flesh, seed) at two phenological stages, pre-véraison véraison. We detected highest content skin, pre-véraison, whereas, véraison, levels were seed. Furthermore, during...
Background and Aims: Chitosan, a chitin deacetylated derivative, is biopolymer able to elicit the plant defence machinery against variety of pathogens. In crop protection, it successfully employed for its low toxicity, mainly virus diseases. this study, efficacy new chitosan formulation (Kendal Cops® (Kc)) was evaluated in grapevine powdery mildew infection. Total polyphenol (TP) content antiradical power different grape tissues experimental wines produced from treated grapes were also...
Abstract: Resistance inducers are a class of agrochemicals, including benzothiadiazole and chitosan, which activate the plant own defence mechanisms. In this work, open-field treatments with activators were performed on two red grape (Vitis vinifera L.) varieties cultivated in different localities, Groppello (Brescia, Lombardia, Italy) Merlot (Treviso, Veneto, Italy). Treatments carried out every 10 days until véraison and, after harvesting, experimental wines (microvinificates) prepared....
Field treatments of grapevine (cv. Merlot) with the plant activator benzothiadiazole (BTH, 0.3 mM) induced resistance against gray mold caused by Botrytis cinerea. Both incidence and severity disease were reduced. The was associated an increase total polyphenols in berry skins, particular, proanthocyanidin fraction, that increased up to 36%. amino acid profile leaves also modified treatments, particularly lysine, augmented 4-fold. Other acids involved mechanisms either biotic or abiotic...
