Early Detection

Baumgartner_SCRIupdateDetection-p1agaqv3dk17odh09dqv56p1o1mKendra Baumgartner
Our goal is to develop a new method to detect trunk diseases by sampling asymptomatic leaves. We revealed a unique set of grape genes expressed in asymptomatic leaves in the early phase of infection, using Botryosphaeria dieback pathogen Neofusicoccum parvum as a model to study host responses to a trunk pathogen.  Tests are in progress to confirm specificity of these grape genes to Neofusicoccum infection, in inoculations with other trunk pathogens, common foliar pathogens, and to rule out possible interactions with drought stress.

Evaluating grapevine germplasm for resistance to Eutypa Dieback

We developed methodologies to rapidly and reliably screen grapevines in the greenhouse.  Now we are examining cultivars and germplasm for sources of resistance to trunk diseases, specifically Eutypa dieback and Phomopsis dieback.

Molecular determinants of wood colonization by trunk pathogens

This is a presentation about the progress we made in understanding the mechanisms underlying grape trunk diseases with the objective to (i) facilitate the development of more accurate diagnostic tools and (ii) assist the effort to identify genetic sources of tolerance in the grape germplasm.

Identifying biochemical and anatomical markers of resistance in grape, almond, and pistachio wood.

The use of varieties resistant to trunk pathogens could mitigate some yield losses encountered by the grape, almond, and pistachio industries. The goal of our research is to identify resistant varieties and to understand the basis of resistance.

Economic benefits of disease prevention in young vineyards.

Kaplan_picJonathan Kaplan
This is a presentation about some of the progress we’ve made on the economic benefits of adoption of preventative practices in young vineyards years before trunk disease symptoms might appear in the vineyard. We set out to determine whether growers might benefit from using these practices in young and mature vineyards.
