Project description
Virus diseases detrimentally affect both the quality and quantity of grapevine fruit production, and the longevity of infected vineyards. The major viral disease in South African vineyards is leafroll, however, new diseases, such as Shiraz disease (SD) and Shiraz decline are becoming more prevalent. The etiological agents of these diseases are unclear at present. The aim of this project is to elucidate the complex viral disease etiology associated with Shiraz disease with a metagenomic sequencing approach using the latest technology in next generation sequencing.
Objectives of the project:
- identify the viruses (incl. variants) associated with Shiraz disease through deep sequencing of diseased and healthy plants.
- design accurate diagnostic assays for Shiraz disease and confirm association of viruses (incl. variants) in larger survey.
- determine the biological contributions of individual viruses to the etiology of Shiraz disease.
- plan effective disease control strategies.
