Restoring Function To A Non-Functional Gene Product Via Guided Cas Systems And Methods Of Use

Patent No. EP3365440 (titled "Restoring Function To A Non-Functional Gene Product Via Guided Cas Systems And Methods Of Use") was filed by Pioneer HI Bred on Oct 17, 2016. The application was issued on Sep 14, 2022.

Patent Summary

This method involves the DNA-free, particle-mediated delivery of a ribonucleoprotein (RNP) complex into a plant cell containing a cell wall. The RNP complex, comprising a Cas endonuclease protein and a guide RNA with a polynucleotide sequence complementary to a genomic target site, is applied to a particle delivery matrix containing a microparticle. Once introduced, the RNP complex binds to the target genomic sequence. The technology is utilized for genome editing, including restoring function to non-functional gene products (e.g., correcting frameshift mutations via NHEJ without a modification template) and modifying nucleotide sequences. The system can employ restored functional selectable markers to identify modified cells without introducing recombinant DNA constructs.
