High Resolution Mapping of the Indica-Derived Rice Blast Resistance Genes II. Pi-ta2 and Pi-ta and a Consideration of Their Origin [PDF]
The indica-derived rice blast resistance genes Pi-ta2 and Pi-ta, introgressed into a japonica background, were mapped on the middle of chromosome 12 with restriction fragment length polymorphism (RFLP)/random amplified polymorphic DNA (RAPD) markers and ...

Intron-targeted gene insertion in rice using CRISPR/Cas9: A case study of the Pi-ta gene
Intron-targeted gene insertion strategy using CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/CRISPR-associated Cas9) has been shown to be a potential tool for crop genetic improvement by targeted mutagenesis or gene replacement of

Identification of a New Locus, Ptr(t), Required for Rice Blast Resistance Gene Pi-ta–Mediated Resistance [PDF]
Resistance to the blast pathogen Magnaporthe oryzae is proposed to be initiated by physical binding of a putative cytoplasmic receptor encoded by a nucleotide binding site-type resistance gene, Pi-ta, to the processed elicitor encoded by the ...

Fitness benefits play a vital role in the retention of the Pi-ta susceptible alleles. [PDF]
Abstract In plants, large numbers of R genes, which segregate as loci with alternative alleles conferring different levels of disease resistance to pathogens, have been maintained over a long period of evolution. The reason why hosts harbor susceptible alleles in view of their null contribution to resistance is unclear.

Transcriptome Analysis and Functional Identification of Xa13 and Pi-ta Orthologs in Oryza granulata [PDF]
Nees & Arn. ex Watt, a perennial wild rice species with a GG genome, preserves many important genes for cultivated rice ( L.) improvement. At present, however, no genetic resource is available for studying .

Statistical inference of selection and divergence of the rice blast resistance gene Pi-ta. [PDF]
AbstractThe 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.

Identifying mutations in sd1, Pi54 and Pi-ta, and positively selected genes of TN1, the first semidwarf rice in Green Revolution. [PDF]
Abstract Background Taichung Native 1 (TN1) is the first semidwarf rice cultivar that initiated the Green Revolution. As TN1 is a direct descendant of the Dee-geo-woo-gen cultivar, the source of the sd1 semidwarf gene, the

Exploring Distribution and Evolution of Pi-ta Haplotypes in Rice Landraces across Different Rice Cultivation Regions in Yunnan. [PDF]
Background: Rice blast, caused by Magnaporthe oryzae, seriously damages the yield and quality of rice worldwide. Pi-ta is a durable resistance gene that combats M. oryzae carrying AVR-Pita1. However, the distribution of the Pi-ta gene in rice germplasms in Yunnan Province has been inadequately studied.

Natural Variation at the Pi-ta Rice Blast Resistance Locus [PDF]
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

Effectiveness and durability of the ricePi-tagene in Yunnan province of China [PDF]
Rice blast is one of the most damaging diseases of rice worldwide. In the present study, we analyzed DNA sequence variation of avirulence (AVR) genes of AVR-Pita1 in field isolates of Magnaporthe oryzae in order to understand the effectiveness of the resistance gene Pi-ta in China. Genomic DNA of 366 isolates of M.
