Enzimi, acidi organici ed altri metaboliti coinvolti nella patogenesi di Penicillium spp
Blue mould caused by Penicillium expansum Link is one of the most destructive rot of pome fruit in all growing areas (Snowdon, 1990; Jones and Aldwinckle, 1991; Tonini,1996) In the past, Penicillium rot has been controlled by fungicide postharvest treatment mainly by thiabendazole (TBZ) and benomyl …

Risposte di resistenza a batteri fitopatogeni di importanti specie coltivate indotte da molecole segnale di diversa natura
… solanacearum) and grapevine crown gall (Agrobacterium vitis). A virulent strain of R. solanacearum race 3 was inhibited by the antagonist on plate. When the pathogen was inoculated 48 h after their application to the root apparatus of tomato plants grown in a climatic chamber, bacterial …

Variation in peach fruit susceptibility to Monilinia laxa and gene expression
… to M.laxa infections, weekly, from the 6thto the 12th week after full bloom (AFB) inoculated with M. laxa or mock-inoculated. The data suggest a critical change in the expression level of the phenylpropanoid pathway from the 7th to the 8th week AFB; such change could be directly physiologically …

Metodi molecolari nello studio della variabilità genetica di Tuber borchii
Tuber borchii (Ascomycota, order Pezizales) is highly valued truffle sold in local markets in Italy. Despite its economic importance, knowledge on its distribution and population variation is scarce. The objective of this work was to investigate the evolutionary forces shaping the genetic structure …

Produzione di virus sintetici per lo studio dei meccanismi di interazione coinvolti nell'induzione di resistenza
Beet soil-borne mosaic virus (BSBMV) and Beet necrotic yellow vein virus (BNYVV) are members of Benyvirus genus. BSBMV has been reported only in the United States while BNYVV has a worldwide distribution. Both viruses are vectored by Polymyxa betae, possess similar host ranges, particles number and …

Studio dei meccanismi molecolari coinvolti nel determinismo sintomatologico di piante infette da virus e virus-satelliti
The aim of our work was to study the molecular mechanisms involved in symptoms appearance of plants inoculated either with a virus or with a virus-satellite complex. In the first case, we tried to set up a reliable method for an early identification of PVYNTN strains present in Italy and causing …

NOVEL PERSPECTIVES IN THE CONTROL OF PLANT PATHOGENIC OOMYCETES
… the productivity, quality and sustainability of agricultural production. Traditionally, the control of oomycete-borne diseases is achieved by means of chemical control based on fungicides. However, the negative impact of these molecules on the environment and the increase of resistant strains in …

Epidemiological studies on primary inoculum of Venturia inaequalis and V. asperata for apple scab management
Apple scab, caused by the ascomycete Venturia inaequalis, is the most important disease of apple, causing great losses worldwide. Its management is largely based on fungicide treatments, especially targeting ascosporic infections. To reduce the pesticide input, sanitation practices against …

INTEGRATED TERRITORIAL APPROACH FOR SUSTAINABLE AGRICULTURE: NITROGEN MANAGEMENT AND SOIL CARBON SEQUESTRATION IN LOMBARDY REGION
In the last years, intensive agriculture and high concentration of livestock activities have become two important environmental concerns, being partially responsible of nitrogen pollution and CO2 emissions caused by carbon loss from soil. That’s particularly true in Lombardy region, due to the …
