Missouri Researchers Engineer Blight-Resistant Rice
University of Missouri scientists used an AI-designed gene-editing tool to develop rice plants resistant to bacterial blight, a disease that threatens harvests across Asia and Africa.

University of Missouri researchers developed rice plants resistant to bacterial blight using OpenCRISPR-1, a gene-editing system developed by California biotechnology company Profluent. The findings were published May 20, 2026, in aBIOTECH, and the resistant plants remain at the laboratory stage.
Why it matters
Bacterial blight can severely reduce both the quantity and quality of rice harvests. The approach shows how open-source, AI-designed gene-editing tools may help strengthen crop defenses against disease.
The study is a laboratory-stage peer-reviewed publication in aBIOTECH, with the resistant rice plants not yet tested in commercial varieties. OpenCRISPR-1 had previously been tested only in animal cells, and the extraction does not report field results.
The players
Bing Yang
Bing Yang is a Curators' Distinguished Professor in the College of Agriculture, Food and Natural Resources at the University of Missouri, who leads the research on blight-resistant rice.
Profluent
Profluent is a California biotechnology company that developed the OpenCRISPR-1 gene-editing system used in the Missouri research.
The details
The team adapted OpenCRISPR-1, which is open source and free for research and commercial crop genome editing, to make targeted DNA changes affecting rice's vulnerability to disease. Researchers are studying how bacterial pathogens interact with rice at the genetic level to identify ways to strengthen the crop's defenses.
Timeline
May 20, 2026: The rice bacterial blight resistance study was published in aBIOTECH.
November 7, 2026: SciTechDaily published an article about the rice research.
Big Picture
The Missouri work extends OpenCRISPR-1, Profluent's open-source gene-editing system, from earlier animal-cell testing into rice. It shows that the tool can be applied to a major food crop, with possible future use in corn and soybeans.
Farmers may have to wait several years before rice varieties developed through this research become available. Corn and soybeans could eventually benefit from similar genetic approaches, though such applications would require further research.
The takeaway
Open-source, AI-designed gene-editing tools could eventually help crops resist disease and environmental stress. Commercial availability for farmers, however, depends on field testing and regulatory approval that have not yet occurred.
What happens next
The next steps are transferring the findings into commercially grown rice varieties, additional testing, regulatory review, and partnerships with companies.
