Indian Scientists Develop First AI-designed Genome Editing Tools for Crop Improvement

Genome editing has emerged as one of the most transformative biotechnological tools for modern agriculture, which enable precise crop improvement with unprecedented speed and accuracy. However, all currently available plant genome editing systems are derived from naturally occurring bacterial or archaeal proteins. In addition, the two most widely used genome editing platforms, Cas9 and Cas12, are protected by complex intellectual property frameworks, limiting their global accessibility and commercial deployment in some regions.

In a recent study published in New Phytologist, researchers from the ICAR-Central Rice Research Institute developed and experimentally validated Plant OpenCRISPR-1 (POC1), an artificial intelligence-designed genome editing nuclease tailored for plant systems. Built upon the OpenCRISPR-1 platform, POC1 represents one of the first AI-designed genome editing systems for crop improvement and commercial applications.

Alongside gene disruption, POC1 can efficiently induce precise point mutations through base editing and prime editing approaches. The researchers demonstrated that POC1-mediated knockout, adenine base editing, cytosine base editing, and prime editing exhibit efficiencies comparable to those of the conventional SpCas9 system while recognizing the same NGG PAM sequence. Stable transformation and validation in regenerated rice plants further confirmed its practical applicability in crops. The study highlights how AI-designed proteins could transform agricultural biotechnology, particularly for the Global South, by potentially improving the accessibility and affordability of genome editing technologies through reduced intellectual property constraints, without compromising editing efficiency.
