As they explain in the report, wood-canker diseases\u00a0are a serious problem in vineyards in the U.S. and other mild grape-growing regions where the trunk of the vine is long-lived. These diseases significantly reduce yields and shorten the lifespan of infected vines, which means that the high startup costs of establishing a vineyard are unlikely to be repaid.<\/div>\n<div>\n<p>With no cure for trunk diseases, prevention is essential. Gaps in our ability to detect the pathogens in the nursery and the field, insufficient knowledge of disease-resistant cultivars, and limited grower adoption of preventive practices contributed to a high disease incidence. Accordingly, the team proposed three objectives, outlined below with highlights of their results as they relate to grape.<\/p>\n<p><strong>Goal 1: Develop new detection tools for diagnosticians, growers and nurseries<\/strong><\/p>\n<ul>\n<li>Developed an assay to\u00a0<strong>detect infection<\/strong>\u00a0of woody tissues as an expression of grape genes and pathogen genes, which can be used in nurseries to screen mother plants and other propagation materials. See\u00a0<a href=\"http:\/\/www.trunkdiseaseid.org\/\" shape=\"rect\">www.TrunkDiseaseID.org<\/a>\u00a0for the team&#8217;s DNA-sequence database on which the assay is based.<\/li>\n<li>Justified to grape growers the need for prevention of trunk diseases in young vineyards, using\u00a0<strong>spore traps for detection of trunk pathogens.<\/strong><\/li>\n<\/ul>\n<p><strong>Goal 2: Identify disease-resistant cultivars and germplasm accessions<\/strong><\/p>\n<ul>\n<li>Collaborated with\u00a0<i>Vitis<\/i>Gen (also an NGWI-supported SCRI project) to\u00a0<strong>identify molecular markers of grape resistance<\/strong>\u00a0to Phomopsis dieback, thereby establishing a basis for future crosses that are trunk-disease resistant. The team notes that, as acceptance of new cultivars in the table-grape industry is high, this work accelerates the possibility of resistant plant material as a long-term approach for trunk-disease management for this sector.<\/li>\n<li><strong>Identified table grapes with resistance to Esca,<\/strong>\u00a0a common trunk disease in California&#8217;s table-grape regions. The team found that the wood anatomy&#8211;particularly the size of the xylem vessels&#8211;seems to render plants more susceptible and may be a phenotype to screen for in breeding Esca-resistant table grapes. With its large xylem vessels, Thompson Seedless is more vulnerable than Flame Seedless and Scarlet Royal, which have smaller vessels.<\/li>\n<\/ul>\n<p><strong>Goal 3: Develop and deploy extension tools that increase adoption of preventative practices in young vineyards<\/strong><\/p>\n<ul>\n<li>Used impactful economic (vs. scientific) data to demonstrate the\u00a0<strong>long-term benefits of prevention.<\/strong>\u00a0The team also created excellent\u00a0<a href=\"http:\/\/treeandvinetrunkdiseases.org\/trunk-disease-management-in-california-preventative-practices-in-young-vineyards-post-infection-practices-in-mature-vineyards\" shape=\"rect\">management plans<\/a>\u00a0and an\u00a0<a href=\"http:\/\/treeandvinetrunkdiseases.org\/economic-tool\" shape=\"rect\">economic decision tool,<\/a>\u00a0available online.<\/li>\n<\/ul>\n<p>Congratulations to Kendra and the team for completing this important project!
