Melatonin content in grape: myth or panacea?
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,…
Traditional knowledge on medicinal and food plants used in Val San Giacomo (Sondrio, Italy)--an alpine ethnobotanical study.
Chemical Diversity and Defence Metabolism: How Plants Cope with Pathogens and Ozone Pollution
The synthesis of ethylene and polyamines can be regulated by ozone at level of S-adenosylmethionine, the biosynthetic precursor of both classes of hormones, which can, therefore, mutually inhibit their own biosynthesis with consequence on plant phenotype.
Chitosan as a MAMP, searching for a PRR
There is a threshold for chitosan concentration able to switch the induction of a cell death programme into necrotic cell death (cytotoxicity) and it must be pointed out that biological activity of chitOSan, besides the plant model, strictly depends on its physicochemical properties.
Chitosan antitranspirant activity is due to abscisic acid-dependent stomatal closure
Phenolic compounds from Achillea millefolium L. and their bioactivity.
The results confirmed A. millefolium as an important source of bioactive metabolites, justifying its pharmaceutical and ethnobotanical use.
Anticancer Molecular Mechanisms of Resveratrol
Promising role to counteract multidrug resistance: in adjuvant therapy, associated with 5-fluoruracyl and cisplatin, resveratrol had additive and/or synergistic effects increasing the chemosensitization of cancer cells.
Benzothiadiazole enhances resveratrol and anthocyanin biosynthesis in grapevine, meanwhile improving resistance to Botrytis cinerea.

Results indicate that BTH treatments, besides improving the content of two important classes of nutraceuticals, with their well-known antioxidant, antitumoral, and phytoestrogenic activities, could be exploited in vineyard to protect grape against gray mould infection, thereby limiting an excessive use of fungicides.

Benzothiadiazole (BTH) Induces Cell-Death Independent Resistance in Phaseolus vulgaris against Uromyces appendiculatus
Histochemical and cytochemical investigations showed that BTH causes hydrogen peroxide accumulation in the treated tissues, and no cell death was detected at BTH concentrations below the phytotoxicity threshold, suggesting that acquired resistance against bean rust is mainly related to the enhanced activity of anionic peroxidases promoted by H 2 O 2 accumulation, thereby leading to cell wall strengthening.
