In this thesis, the different inoculating methods, including leaves in vitro and in vivo and whole plants being inoculated were studied, and the resistance to blast of rice in cultivars was identified by these methods.
Resistance of 3255 Sichuan rice germplasm( O. Saliva. L. ) to rice blast(Pyricularia oryzae Cav, )were identified- The results showed that there existed various kinds of resistant resources in the local rice germplasm. The germplasm resistant to seedling blast of rice were more than those resistant to leaf or neck blast.
Tenuazonic acid, toxin of rice blast fungus, induces disease resistance and reactive oxygen production in plants
Furthermore, transgenic F1 plants, resulting from a cross of R2 homozygous lines with high resistance to rice blast with the non-transgenic male sterile line Peiai 64S, showed not only high resistance to M.
Resistance to rice blast (Pyricularia oryzae) caused by the expression of trichosanthin gene in transgenic rice plants transferr
In antifungal assay the degrees of rice blast (Pyricularia oryzae) infection of the transgenic plants expressing trichosanthin and expressingGUS gene as control have been evaluated.
The differences such as the time of disease symptom observed, the number of infected plants and damaged leaves, the growth of infected plants of the two transgenic plants after being inoculated by rice blast (Pyricularia oryzae) are significant.
trichocarpa (AF057708) determined by blast analysis in the GenBank.
This new cultivar also has other characteristics such as enhanced resistance of blast and fallen, steady productivity, and strong adaptability.
The successes of breeding Jiafuzhan is a solution to the existing perennial problems in the rice industry, such as poor grain quality of big-grain rice and early indica rice, low productivity, and poor blast resistance of elite rice.
In recent clinical studies we targeted the increased IMP dehydrogenase activity in leukemic blast cells by an inhibitor drug, tiazofurin, and achieved 77% responses, including complete remissions.
A BLAST analysis revealed an open reading frame (ORF) that appears to encode for the Tetrahymena DNA-[adenine] methyltransferase ((MTase), based on the presence of motifs characteristic of the enzymes in prokaryotes.
Defense mechanism of the rice plant against rice blast disease
grisea), the causal agent of rice blast disease, was generated from segregation data utilizing 97 RFLP markers, two isoenzyme loci and the mating type locus among progeny of a cross between parental strains Guy 11 and 2539.
Saturation mapping with subclones of YACs: DNA marker production targeting the rice blast disease resistance gene, Pi-b
Rice blast disease is a major constraint for rice breeding.
The rice Pi5(t) locus confers broad-spectrum resistance to Magnaporthe grisea, the causal agent of rice blast disease.
