gene-editing-tools
Gene-editing tools are molecular techniques, such as CRISPR-Cas9, that allow scientists to precisely modify, add, or remove specific sequences within an organism's DNA. In plant science, these tools have transformed the ability to engineer crops with desired traits—such as disease resistance, drought tolerance, or improved nutritional profiles—far more rapidly and precisely than traditional breeding methods. They also serve as powerful research instruments for uncovering the function of individual genes in plant development, metabolism, and stress response.

Scientists tested 50 different CRISPR-style gene-editing tools side by side, ranking them on cutting efficiency, accuracy, and safety. The results provide the first comprehensive guide for choosing the right molecular tool for precise genome editing applications, including crop improvement.
AsCas12a-Ultra, LbCpf1, and AsCas12a-Plus matched or exceeded SpCas9 (the current gold-standard editing tool) in cutting efficiency across the 50 systems tested
enCas12f-HKRA frequently caused chromosomal translocations — dangerous large-scale DNA rearrangements — while Cas12j-SF05 posed significantly lower risk of such structural damage
enRhCas12f1 and SpaCas12f1 showed the lowest cell toxicity of any system tested, whereas enAsCpf1-HF strongly inhibited cell proliferation, flagging it as a safety concern
