Establishment of grapevine leafroll associated virus 1 and 2 ELISAs

Project number: PATHSOL GP 24-02
Project leader: Prof Gerhard Pietersen
This project aims to develop ELISA tests to detect GLRaV-1 and GLRaV-2 and, if successful, combine them into a GLRaV1, -2, & -3 cocktail ELISA, which can detect all three viruses within a single test.

Critical wine analyses for monitoring authenticity adulteration – Tools for the authentication of South African wines

Project number: FShip P04000340
Project leader: Dr Francois van Jaarsveld
This project aims to allow for additional analytical capacity and investigate the effectiveness of Fourier transform infrared spectroscopy (FT-IR) as a cost-effective screening tool for the authentication of wines, including all variations caused by grape cultivar, geographic location, and vintage. FT-IR and other methods in the authenticity studies will be compared and validated for their feasibility for the local authentication of South African wines.

South African de-alcoholised wines

Project number: SAGWRI WDT 24-01
project leader: Prof Wessel du Toit
The project aims to obtain new information on how to improve the quality and stability of de-alc wines.

CRISPR-2: first applications for virus resistance and drought tolerance

Project Number: FShip GenUS 21-01
Project leaders: Vivier, M & Burger, J
This project aims to provide proof of the principle of gene manipulation, specifically genome editing, as an approach to developing grapevine plant material (both scion and rootstock) that can withstand drought better.
