The genus Neofusicoccum is comprised of approximately 50 species with a worldwide distribution and typically associated plants. well-known for the diseases it causes on economically ecologically relevant host In particular, members this are responsible grapevine diseases, such as leaf spots, fruit rots, shoot dieback, bud necrosis, vascular discoloration wood, perennial cankers. Many secondary ...

Grapevine rupestris stem pitting-associated virus (GRSPaV) is a worldwide-distributed pathogen in grapevines with a high genetic variability. Our study revealed differences in the complexity of GRSPaV population in a single host. A single-variant GRSPaV infection was detected from the SK30 grapevine plant. On the contrary, SK704 grapevine was infected by three different GRSPaV variants. Variant...

Whole-genome comparisons of Vitis vinifera subsp. sativa and V. vinifera subsp. sylvestris are expected to provide a better estimate of the valuable genetic diversity still present in grapevine, and help to reconstruct the evolutionary history of a major crop worldwide. To this aim, the increase of molecular marker density across the grapevine genome is fundamental. Here we describe the SNP dis...

A nonpathogenic strain of Rhizobium vitis ARK-1 was tested as a biological control agent for grapevine crown gall. When grapevine roots were soaked in a cell suspension of strain ARK-1 before planting in the field, the number of plants with tumors was reduced. The results from seven field trials from 2009 to 2012 were combined in a meta-analysis. The integrated relative risk after treatment wit...

Grapevine leafroll (LR) and corky bark (CB) diseases occur wherever grapevines are grown and are associated with undesirable viticultural effects which include delayed ripening of fruit, reduced yield, altered fruit pigmentation, and reduced accumulation of sugar (6,24). Rootstockscion incompatibility (RSI) is a disease syndrome characterized by incompatibility at the graft union resulting in s...
