Haplotype Diversity at the Pi-ta Locus in Cultivated Rice and Its Wild Relatives [PDF]
The Pi-ta gene in rice confers resistance to races of Magnaporthe oryzae that contain AVR-Pita. Pi-ta encodes a predicted cytoplasmic receptor protein with a nucleotide-binding site and a leucine-rich domain. A panel of 51 Oryza accessions of AA genome species Oryza sativa, O. glaberrima, O. rufipogon, O. nivara, and O.

A Telomeric Avirulence Gene Determines Efficacy for the Rice Blast Resistance Gene Pi-ta [PDF]
Genetic mapping showed that the rice blast avirulence gene AVR-Pita is tightly linked to a telomere on chromosome 3 in the plant pathogenic fungus Magnaporthe grisea. AVR-Pita corresponds in gene-for-gene fashion to the disease resistance (R) gene Pi-ta.

Fitness benefit plays 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 resistance to pathogens, have been maintained over a long evolutionary time.

OUTCOMES AND EFFECTIVENESS OF PERCUTANEOUS INTERVENTION IN PATIENTS WITH TAKAYASU’S ARTERITIS
Aim. Takayasu’s arteritis (TA) is a chronic inflammatory disease that affects predominantly the aorta. Percutaneous intervention (PI) may be use the TA. In this manuscript, we studied the outcomes (in-hospital and 6 months later) and effectiveness of PI ...

Projective prime ideals and localisation in pi-rings [PDF]
The results here generalise [2, Proposition 4.3] and [9, Theorem 5.11]. We shall prove the following. THEOREM A. Let R be a Noetherian PI-ring. Let P be a non-idempotent prime ideal of R such that PR is projective. Then P is left localisable and RP is

Molecular Evolution of thePi-taGene Resistant to Rice Blast in Wild Rice (Oryza rufipogon) [PDF]
AbstractRice blast disease resistance to the fungal pathogen Magnaporthe grisea is triggered by a physical interaction between the protein products of the host R (resistance) gene, Pi-ta, and the pathogen Avr (avirulence) gene, AVR-pita. The genotype variation and resistant/susceptible phenotype at the Pi-ta locus of wild rice (Oryza rufipogon), the ...

Indica and japonica crosses resulting in linkage block and recombination suppression on rice chromosome 12. [PDF]
Understanding linkage block size and molecular mechanisms of recombination suppression is important for plant breeding. Previously large linkage blocks ranging from 14 megabases to 27 megabases were observed around the rice blast resistance gene Pi-ta in

Rice Pi-ta gene Confers Resistance to the Major Pathotypes of the Rice Blast Fungus in the United States [PDF]
The Pi-ta gene in rice prevents the infection by Magnaporthe grisea strains containing the AVR-Pita avirulence gene. The presence of Pi-ta in rice cultivars was correlated completely with resistance to two major pathotypes, IB-49 and IC-17, common in the U.S. blast pathogen population.

Evolutionary Dynamics of the Genomic Region Around the Blast Resistance Gene Pi-ta in AA Genome Oryza Species [PDF]
Abstract The race-specific resistance gene Pi-ta has been effectively used to control blast disease, one of the most destructive plant diseases worldwide. A single amino acid change at the 918 position of the Pi-ta protein was known to determine resistance specificity.
