Abstract: The present disclosure involves the production of Waxy maize. Compositions and methods are provided for knocking out expression of the Waxy (Wx1) gene in maize by making double strand breaks at one or more target sites in an endogenous WX1 encoding sequence. Some methods employ one or more guide polynucleotides and a Cas endonuclease, wherein Cas endonuclease is guided by the one or more guide polynucleotides to recognize and introduce double strand breaks at specific target sites in and around the Wx1 gene. Also provided are compositions and methods for the production of Waxy maize plant cells, plant explants, seeds and grain.

Abstract: The field is molecular biology, and more specifically, methods for chromosomal engineering of multiple native genes, such as disease resistance genes in a genomic locus using site-specific editing to produce plants. Also described herein are methods of generating heterologous genomic locus in a plant that comprises a plurality of intraspecies polynucleotide sequences.

Abstract: Compositions and methods for obtaining plant cells with modified Ht1 nucleotide sequences, modified NLB18 sequences, or both, are provided herein. The methods involve introducing double-strand breaks into the maize genome in an endogenous Ht1 encoding sequence, an endogenous NLB18 encoding sequence, or both, to modify the genomic sequence in order to enhance northern leaf blight resistance of a plant produced from the plant cell. Further provided are methods that introduce resistant alleles of Ht1 and/or NLB18 into specific sites in the genome. Plants produced by the plant cells, and seeds produced from the plants are also included. Guide polynucleotides are also provided for the use of the CRISPR-Cas system in inducing double strand breaks.
