New CRISPR-Based Method Boosts Agricultural Resilience
Scientists from Tel Aviv University, the University of Chinese Academy of Sciences, and Israeli agri-tech firm NetaGenomiX have unveiled a groundbreaking gene-editing approach that could revolutionize global agriculture. Their innovation addresses key limitations of traditional CRISPR technology, enabling large-scale editing of gene families in plants.
Overcoming Genetic Redundancy
Previous CRISPR methods struggled with 'genetic redundancy,' where similar genes compensate for edited ones, limiting effectiveness. The team developed an algorithm creating CRISPR libraries capable of targeting thousands of related genes simultaneously. In trials with 1,300 tomato plants, researchers tracked how genetic modifications influenced traits like sweetness, shape, and disease resistance.
Sweet Success in Tomato Trials
Published in Nature Communications, results showed edited plants produced fruits with varying sugar levels and improved disease resistance. The technology demonstrated unprecedented precision in modifying taste, size, and resilience – critical factors for addressing climate-driven agricultural challenges.
Global Food Security Implications
Researchers are now adapting the method for rice and other staple crops. This advancement comes as climate change and population growth intensify pressure on food systems. The technology could accelerate development of hardier crop varieties, potentially transforming agricultural practices worldwide.
