Chemical Diversity and Defence Metabolism: How Plants Cope with Pathogens and Ozone Pollution
Chemical defences represent a main trait of the plant innate immune system. Besides regulating the relationship between plants and their ecosystems, phytochemicals are involved both in resistance… Expand

ETHNOPHARMACOLOGICAL RELEVANCE This work increases the ethnobotanical data from Northern Italy and, in particular, the Lombardy region, till now poorly documented, safeguarding the local folk… 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
Chitosan as a MAMP, searching for a PRR
Chitosan, a deacetylated chitin derivative, behaves like a general elicitor, inducing a non-host resistance and priming a systemic acquired immunity. The defence responses elicited by chitosan… 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 foliar… Expand

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… Expand
Phenolic compounds from Achillea millefolium L. and their bioactivity.
Since antiquity, Achillea millefolium L. (Asteraceae) has been used in traditional medicine of several cultures, from Europe to Asia. Its richness in bioactive compounds contributes to a wide range… Expand
The ectopic expression of the rice Osmyb4 gene in Arabidopsis increases tolerance to abiotic, environmental and biotic stresses
Abstract The Osmyb4 rice gene encodes a Myb transcription factor involved in cold acclimation. Its constitutive expression in Arabidopsis thaliana results in improved cold and freezing tolerance.… Expand
Chemical-induced resistance against powdery mildew in barley: the effects of chitosan and benzothiadiazole
Chitosan (CHT), a deacetylated chitin derivative, and benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH), a non toxic synthetic functional analogue of salicylic acid, were applied as… Expand
Benzothiadiazole (BTH) Induces Cell-Death Independent Resistance in Phaseolus vulgaris against Uromyces appendiculatus
Benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH), trade name Bion®, was used to induce resistance in bean cultivars Borlotto Nano Lingua di Fuoco (BLF), Borlotto Taylor, Cannellino,… Expand
