Researchers from Stellenbosch University and the Agricultural Research Council have achieved a first for Africa: the successful DNA editing of a woody crop plant. Using CRISPR technology, the team made precise changes to grapevine DNA by “switching off” a single gene, VvDMR6.1, which is associated with the plant’s disease response. The researchers say the edit made the grapevine plants less susceptible to downy mildew, a major disease affecting …
