　　Male sterile genes and mutants are valuable resources in hybrid seed production for monoclinous crops.High genetic redundancy due to allohexaploidy makes it difficult to obtain the nuclear recessive male sterile mutants through spontaneous mutation or chemical or physical mutagenesis methods in wheat.The emerging effective genome editing tool,CRISPR/Cas9 system,makes it possible to achieve simultaneous mutagenesis in multiple homoeoalleles.To improve the genome modification efficiency of the CRI...
