The life cicle of Plasmopara viticola
2000
Plasmopara viticola (Berk. & M. A. Curtis) Bed. & De Toni is an obligate biotrophic oomycetous organism which causes downy mildew of grape vine. An understanding of its life-cycle is essential in relation to the pathology and epidemiology, and for the development of better control of the disease. It overwinters as oospores within fallen leaves.

Naphthalenone polyketides produced by Neofusicoccum parvum, a fungus associated with grapevine Botryosphaeria dieback
2016
A strain of Neofusicoccum parvum isolated from declining vines was pathogenic to grapevine cultivar Inzolia in Sicily. This strain produced some metabolites in liquid medium. Crude extract, through a bio-guided purification process, yielded four naphthalenone polyketides. They were identified by comparison with spectroscopic data and optical proprieties reported in literature as: (3S, 4S)-7-ethyl-3,4,8-trihydroxy-6-methoxy-3,4-dihydro-1-(2H)-naphthalenone, (3S*, 4S*)-3,4-dihydro-3,4,8-trihydroxy-7-(1-hydroxyethyl)-6-methoxy-1-(2H)-naphthalenone, (4S)-3,4-dihydro-4,8-dihydroxy-1-(2H)-naphthalenone, named botryosphaerones D and A, isosclerone, respectively, and (3S*,4S*)-3,4,5-trihydroxy-1-…
Stato sanitario e micorrizazione in specie arboree forestali: casi studio in Italia
2016
La sanità delle piante è notoriamente correlata a elevati livelli di micorrizazione, soprattutto in ospiti strettamente dipendenti dalla simbiosi. Eventuali fattori di stress, abiotici o biotici, agenti di deperimento alterano il bilancio fotosintetico e influenzano, spesso negativamente, l’associazione mutualistica, aggravando così lo stato di sofferenza delle piante. Relativamente alle piante forestali, diversi studi hanno confermato l’intima interazione tra stato sanitario e micorrizazione. In questa nota si riportano i risultati di nostre indagini, condotte in due Regioni ecologicamente molto diverse, Lazio e Sicilia, rilevando lo stato micorrizico di piante di Fagus sp., Pinus sp. e Qu…
Oxidative Stress in the Pathogenesis of Aorta Diseases as a Source of Potential Biomarkers and Therapeutic Targets, with a Particular Focus on Ascend…
2022
Aorta diseases, such as ascending aorta aneurysm (AsAA), are complex pathologies, currently defined as inflammatory diseases with a strong genetic susceptibility. They are difficult to manage, being insidious and silent pathologies whose diagnosis is based only on imaging data. No diagnostic and prognostic biomarkers or markers of outcome have been known until now. Thus, their identification is imperative. Certainly, a deep understanding of the mechanisms and pathways involved in their pathogenesis might help in such research. Recently, the key role of oxidative stress (OS) on the pathophysiology of aorta disease has emerged. Here, we describe and discuss these aspects by revealing some OS …
