  • Nucleic acid markers for rice blast resistance genes and rice blast resistance genes isolated by the use of these markers
    Patent number: 6333151
    Abstract: The present invention provides nucleic acid markers for rice blast resistance genes Pi-ta and Pi-ta2, which hybridize with any RFLP probes isolated from rice genomic DNA and are located within a distance of 2.0 cM from rice blast resistance genes Pi-ta or Pi-ta2. According to the present invention, it becomes possible to easily identify rice blast resistance genes and related genes from rice cultivars containing Pi-ta or Pi-ta2, thus promoting development and breeding of superior cultivars. It becomes also possible to easily carry out a resistance test of rice. This will open up way to create new resistance genes.
    Type: Grant
    Filed: July 29, 1994
    Date of Patent: December 25, 2001
    Assignees: Research Development Corporation of Japan, National Institute Agrobiological Resources Ministry of Agriculture Forestry and Fisheries
    Inventors: Shinji Kawasaki, Masaya Satoh, Naoki Katsura, Akira Saitoh, Ikuo Andoh

  • Nucleic acid markers for rice blast resistance genes and rice blast resistance genes isolated by the use of these markers
    Patent number: 5674993
    Abstract: The present invention provides nucleic acid markers for rice blast resistance genes, which are isolated from the rice genomic DNA, are DNA sequences having a total length of up to 2 kb, with two identical sequences of at least ten bases at the both ends thereof and are located within a distance of 2.0 cM from rice blast resistance genes Pi-b, Pi-ta or Pi-ta.sup.2 . According to the present invention, it becomes possible to easily isolate rice blast resistance genes and related genes from rice cultivars containing Pi-b, Pi-ta.sup.2 or Pi-ta, thus promoting development and breeding of superior cultivars. It becomes also possible to easily carry out a resistance test of rice. This will open up the way to create new resistance genes.
