This review illuminates key findings in our understanding of grapevine xylem resistance to fungal vascular wilt diseases. Grapevine (Vitis spp.) vascular diseases such as esca, botryosphaeria dieback, and eutypa dieback, are caused by a set of taxonomically unrelated ascomycete fungi. Fungal colonization of the vascular system leads to a decline of the plant host because of a loss of the xylem ...

Defense mechanisms in woody tissue are poorly understood, especially in vine colonized by trunk pathogens. However, several investigations suggest that molecular mechanisms in the central tissue of Vitis vinifera L. may be involved in trunk-defense reactions. In this work, the perception of Phaeoacremonium aleophilum and Phaeomoniella chlamydospora alone or together were investigated in cutting...

Growing grapevine (Vitis vinifera) is a key contribution to the economy of many countries. Tools provided by genomics and bioinformatics did help researchers in obtaining biological knowledge about the different cultivars. Several genetic markers for common diseases were identified. Recently, the impact of microbiome has been proved to be of fundamental importance both in humans and in plants f...

A significant reduction in vine production has recently been recorded in several vine regions in Algeria due to the death (total or partial) of many vines and to the pulling of many vineyards that had showed too many symptoms of decline. This study was conducted during spring 2010 2012 to detect the responsible agents for this disease. Samples of grapevine wood were collected in five grapevine ...

Grapevine crown gall (GCG), which is caused by tumorigenic Allorhizobium vitis (=Rhizobium vitis), the most important bacterial disease in grapevine, and its economic impact on grapevine very high. When young vines develop GCG, they often die, whereas older may show stress poor growth depending severity of because GCG interferes with vascular system trunk prevents nutrient flow, leading to infe...

the incidence of grapevine virus a (gva) is reported from almost all of the major grapevine growing regions in iran. grapevine is vegetatively propagated by rooting of cuttings or grafting. in such plants, viral diseases are transmitted from stock plants to the progeny. therefore, the control of grapevine viruses can be achieved primarily through production of healthy stock plants. in the p...
