Biocontrol Potential of an Endophytic Strain against the Grapevine Trunk Disease Pathogen and Its Mechanism of Action.

Grapevine trunk diseases (GTDs) impact the sustainability of vineyards worldwide and management options are currently limited. Biological control agents (BCAs) may offer a viable alternative for disease control. With an aim to develop an effective biocontrol strategy against the GTD pathogen , this study investigated the following: (1) the efficacy of the strains in suppressing the BD pathogen in detached canes and potted vines; (2) the ability of a strain of (BCA17) to colonize and persist within grapevine tissues; and (3) the mode of action of BCA17 to antagonize .

Production of Phytotoxic Metabolites by Botryosphaeriaceae in Naturally Infected and Artificially Inoculated Grapevines.

Grapevine trunk diseases (GTDs) are considered a serious problem to viticulture worldwide. Several GTD fungal pathogens produce phytotoxic metabolites (PMs) that were hypothesized to migrate to the foliage where they cause distinct symptoms. The role of PMs in the expression of Botryosphaeria dieback (BD) symptoms in naturally infected and artificially inoculated wood using molecular and analytical chemistry techniques was investigated.

Diversity Profiling of Grapevine Microbial Endosphere and Antagonistic Potential of Endophytic Against Grapevine Trunk Diseases.

Grapevine trunk diseases (GTDs) are a serious problem of grapevines worldwide. The microbiota of the grapevine endosphere comprises prokaryotic and eukaryotic endophytes, which may form varied relationships with the host plant from symbiotic to pathogenic. To explore the interaction between grapevine endophytic bacteria and GTDs, the endomicrobiome associated with grapevine wood was characterized using next-generation Illumina sequencing.
