COMPOSITIONS AND METHODS OF MODIFYING A PLANT GENOME TO PRODUCE A MS1 OR MS5 MALE-STERILE PLANT

摘要

Compositions and methods are provided for genome modification of a nucleotide sequence located in or near a male fertility gene of Ms1 or Ms5 in the genome of a plant cell or plant to produce a male-sterile plant. In some examples, the methods and compositions employ a guide RNA/Cas endonuclease system for modifying or altering target sites located in or near a male fertility gene of Ms1 or Ms5 in the genome of a plant cell, plant or seed to produce a male-sterile plant. Also provided are compositions and methods employing a guide polynucleotide/Cas endonuclease system for genome modification a nucleotide sequence located in or near a male fertility gene of Ms1 or Ms5 in the genome of a plant cell to produce a male-sterile plant. Compositions and methods are also provided for restoring fertility to a Ms1 or Ms5 nucleotide sequence to a male-sterile Ms1 or Ms5 plant produced using the methods and compositions described herein.
