Tóm tắt

BACKGROUND: Wild relatives have substantial impacts on the resistance of wheat to biotic and abiotic stresses. The genetic diversity of these wild varieties can be employed to widen the wheat gene pool by introducing wild allele introgression and genome structure variations. The powdery mildew resistance gene Pm13 was derived from the wheat wild relative species Aegilops longissima (S RESULTS: In this study, translocations between the Pm13 introgression and wheat homoeologous A, B and D chromosomes were developed by using a wheat ph1b mutant. The 3S CONCLUSIONS: Our results provide novel alien homoeologous Pm13 translocations for improving powdery mildew resistance in wheat and insights into the interactions between different wheat genomes and alien chromosome segments.
