Review of CRISPR-Cas9 Crop Applications and Implications in Africa

Researchers from Lupane State University in Zimbabwe and partners reviewed the applications of CRISPR-Cas9 in producing climate-resilient crops that will help smallholder farmers in Africa.

The growth of the African population is threatened by malnutrition, food insecurity, and climate change. Africa's crop productivity is also declining due to drought and unpredictable precipitation patterns. To address these challenges, scientists use CRISPR-Cas9 to develop crops with enhanced traits, such as nutrition, drought tolerance, and disease resistance.

The researchers gave a comprehensive review of articles related to the usage of CRISPR gene editing for crop improvement in Africa. They highlighted the implications of CRISPR in developing climate-resilient crops, such as banana, wheat, and Ethiopian mustard. Social, ethical, and safety concerns regarding the adoption of gene-edited crops were also discussed. Their findings showed that growing gene-edited crops with stress resistance and better yields will help contribute to sustainable agriculture and food security in Africa.
