Development of Dominant Rice Blast Pi-ta Resistance Gene Markers
genotypes can be easily identified (Huang et al., 1997; Hittalmani et al., 2000). A PCR-based Pi-ta gene marker Incorporation of resistance genes into existing rice (Oryza sativa is useful in marker-assisted selection breeding since it L.) cultivars is a powerful strategy and is commonly applied in breeding rice resistance to blast disease [caused by Pyricularia grisea Sacc. is the part of resi...
متن کاملNatural Variation at the Pi-ta Rice Blast Resistance Locus.
ABSTRACT The resistance gene Pi-ta protects rice crops against the fungal pathogen Magnaporthe grisea expressing the avirulence gene AVR-Pita in a gene-for-gene manner. Pi-ta, originally introgressed into japonica rice from indica origin, was previously isolated by positional cloning. In this study, we report the nucleotide sequence of a 5,113-base pair region containing a japonica susceptibili...
متن کاملpyramiding of blast resistance genes pi-1 and pi-2 in tarom mahalli rice cultivar
blast (magnaporthe grisea) is the most important disease of rice in mazandaran province, north of iran, which causes severe damages annually on susceptible cultivars. tarom mahalli is a local aromatic cultivar with high cooking quality and marketability, but very susceptible to blast. to protect this cultivar and similar susceptible cultivars against rice blast, farmers have to use high amounts...
متن کاملStatistical Inference of Selection and Divergence of the Rice Blast Resistance Gene Pi-ta
The resistance gene Pi-ta has been effectively used to control rice blast disease, but some populations of cultivated and wild rice have evolved resistance. Insights into the evolutionary processes that led to this resistance during crop domestication may be inferred from the population history of domesticated and wild rice strains. In this study, we applied a recently developed statistical met...
متن کاملIntrogression of Blast Resistance Genes (Putative Pi-b and Pi-kh) into Elite Rice Cultivar MR219 through Marker-Assisted Selection
Blast is the most common biotic stress leading to the reduction of rice yield in many rice-growing areas of the world, including Malaysia. Improvement of blast resistance of rice varieties cultivated in blast endemic areas is one of the most important objectives of rice breeding programs. In this study, the marker-assisted backcrossing strategy was applied to improve the blast resistance of the...
