Rapid survey for presence of a blast resistance gene Pi‐ta in rice cultivars using the dominant DNA markers derived from portions of the Pi‐ta gene

Plant Breeding, 2007
AbstractThe Pi‐ta gene in rice confers resistance to strains of the blast pathogen Magnaporthe grisea (Herbert) Borr. (anamorph Pyricularia oryza Cav.) containing the corresponding avirulence gene AVR‐Pita in a gene‐for‐gene fashion. The Pi‐ta gene is a typical nucleotide‐binding site type resistance gene.

Development of Dominant Rice Blast Pi‐ta Resistance Gene Markers

Crop Science, 2002
ABSTRACTIncorporation of resistance genes into existing rice (Oryza sativa L.) cultivars is a powerful strategy and is commonly applied in breeding rice resistance to blast disease [caused by Pyricularia grisea Sacc. = P. oryzae Cavara (teleomorph: Magnaporthe grisea (Hebert) Barr)].

Characterization ofPi-tablast resistance gene in an international rice core collection

Plant Breeding, 2009
With 3 figures and 3 tables Abstract The Pi-ta gene in rice prevents the infections by races of Magnaporthe oryzae containing AVR-Pita. In the present study, 1790 accessions were characterized for Pi-ta, and Pi-ta independent resistance genes using marker analysis, disease evaluation with the race IB-49 carrying AVR-Pita, and IE-1k not carrying AVR-

Development of a SNLP marker from the Pi-ta blast resistance gene by tri-primer PCR

Euphytica, 2004
The Pi-ta gene from indica introgressed into japonica rice has been used to control the blast disease caused by the fungal pathogen Magnaporthe grisea (Herbert) Barr. (anamorph Pyricularia oryzae Cav.) worldwide. A single nucleotide length polymorphism (SNLP) was identified at the intron region of the Pi-ta gene to develop a codominant Pi-ta gene ...

Field Resistance Expressed when the Pi-ta Gene is Compromised by Magnaporthe oryzae

2009
The Pi-ta gene provided 14 years of durable resistance to contemporary field population of Magnaporthe oryzae in southern USA rice production areas before being overcome during 2004 in ‘Banks’, a Pi-ta-based cultivar, by race IE-1k of the blast pathogen.

Screening for the rice blast resistance gene Pi-ta using LNA displacement probes and real-time PCR

Molecular Breeding, 2006
Single nucleotide polymorphisms (SNPs) will become a molecular breeding tool of increasing significance as a growing range of SNP data becomes available. In order for these markers to be incorporated into breeding programs, simple, high throughput and low cost detection methods need to be available.

Understanding the Co-evolution of the Rice Blast Resistance Gene PI-TA and Magnaporthe oryzae Avirulence Gene AVR-PITA

2009
The Pi-ta gene in rice effectively prevents infection by races of Magnaporthe oryzae that contain the corresponding AVR gene, AVR-Pita. Pi-ta is a putative cytoplasmic protein with a centrally located nucleotide binding sites (NBS) and a leucine rich domain (LRD) at the carboxyl terminus.

Artificial introgression of a large chromosome fragment around the rice blast resistance gene Pi-ta in backcross progeny and several elite rice cultivars

Heredity, 2009
Studying the size of genomic introgressions should lead to a better understanding of linkage disequilibrium in crop breeding. In this study, progeny of the cross between a tropical japonica rice cultivar Katy containing the rice blast resistance gene Pi-ta and a temperate japonica cultivar M202 (pi-ta)' [corrected].
