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. Expand
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,Expand
Traditional knowledge on medicinal and food plants used in Val San Giacomo (Sondrio, Italy)--an alpine ethnobotanical study.
The calculated indices demonstrated that in the studied area there is a small retention of plant knowledge, and could be the basis for subsequent research on the species that are interesting from a phytochemical point of view and on the potential use of their active metabolites. Expand
Chitosan antitranspirant activity is due to abscisic acid-dependent stomatal closure
Abstract Chitosan (CHT) is a natural compound able to activate the plant own defence machinery against pathogen attacks and to reduce both transpiration and stomatal opening when applied as foliarExpand
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. Expand
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. Expand
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.

Melatonin in traditional Mediterranean diets
In this view, the presence of melatonin in some Mediterranean foods and beverages adds a new element to the hypothesis of health benefits associated to Mediterranean dietary patterns, although the available data are still preliminary and incomplete. Expand
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.

The ectopic expression of the rice Osmyb4 gene in Arabidopsis increases tolerance to abiotic, environmental and biotic stresses
Analysis of biochemical and physiological differences between Osmyb4 -expressing and wild-type plants found increased levels of several amino acids that are involved in stress adaptation, acting as osmolytes, scavengers and/or metabolite precursors. Expand
