We have recently produced EMS-induced knock-out mutations at the Gc2 locus that were derived from Ae. sharonensis. Our data suggest that the Gc2 mutant is a knock-out of the gene encoding for the breaking agent. For analyzing the interactions of the Gc2 mutants with other Gc genes from different Aegilops species, we have crossed stocks with functional and mutant Gc2 genes with stocks having Gc ...
