Complete sequence, genotyping and comparative analysis of Pepino mosaic virus discovered isolates from Italy

2011

Pepino mosaic virus (PepMV) causes economic damage to the tomato industry worldwide. In Italy, the virus is endemic in Sicily, an important tomato-production region, and a new outbreak has been recorded in Sardinia after the first PepMV appearance in 2001. Italian PepMV isolates from these two geographically distant regions were molecularly characterized and the complete nucleotide sequence of four isolates was determined by walking primer strategy. The complete nucleotide and deduced amino acid sequences were analyzed and compared with published PepMV sequences. Italian isolates belong to the PepMV-Ch2 strain and had 97.2% to 98.5% identity with those of the reference PepMV-Ch2 deposited i…

Root and crown tot of olive caused dy Phytophthora spp.

2011

Phytophthora root and crown rot has been traditionally considered a minor disease of olive. However, in recent years it has been recognized as an emerging problem in several olive-growing countries such as Australia, Italy and Spain probably as a consequence of the expansion of plantings in new areas with heavy soils and the more intensive use of irrigation in both olive nurseries and commercial groves. The disease has been reported from most olive-growing countries and is caused by several soil -borne species of Phytophthora, including P. cinnamomi, P. citricola, P. cryptogea, P. drechsleri, P. gonapodyides, P. inundata, P. megasperma,P. nicotianae and P.palmivora. Diagnosis is currently b…

Studio delle popolazioni di aspergilli e penicilli in uve della sicilia occidentale

2008

In diversi vigneti della Sicilia occidentale è stata monitorata, su uve sane e infestate, la dinamica di presenza di specie di Aspergillus e Penicillium, alcune delle quali note produttrici di ocratossina A, la principale micotossina della filiera vitivinicola. Gli studi condotti dall’allegagione alla raccolta evidenziano la variabilità quali-quantitativa delle popolazioni di aspergilli e penicilli, in relazione alle condizioni ambientali. Le analisi tossicologiche, accertando la presenza occasionale della micotossina, confermano l’assenza di correlazione tra il livelli di OTA nelle uve e la presenza dei funghi in vigneto.

In semi-vivo antagonism of Acremoninum byssoides towards Plasmopara viticola

2008

In previous laboratory tests the culture filtrates and the crude extracts obtained from Acremonium byssoides were shown to completely inhibit Plasmopara viticola sporangia germination. A study was thus undertaken in order to investigate on the possible inhibiting activity of the hyphomycete towards pathogenesis of the oomycete in grapevine. A. byssoides was cultivated on malt-extract agar (MEA) to obtain pure colonies and on maltextract broth (MEB) to obtain culture filtrate and crude extract. Healthy leaves of grapevine were put in Petri dishes containing sporangia suspended in: deionized sterile water, malt-extract broth, dimethylsulfoxide (DMSO), culture filtrate, crude extract and a sus…
