Abstract

The disclosure provides novel corn, tomato, and soybean U6, U3, U2, U5, and 7SL snRNA promoters which are useful for CRISPR/Cas-mediated targeted gene modifications in plants. The disclosure also provides methods for use for U6, U3, U2, U5, and 7SL promoters in driving expression of sgRNA polynucleotides which function in a CRISPR/Cas system of targeted gene modification in plants. The disclosure also provides methods of genome modification by insertion of blunt-end DNA fragments at a site of genomic cleavage.
