The Potential of Streptomyces as Biocontrol Agents against the Rice Blast Fungus, Magnaporthe oryzae (Pyricularia oryzae)
Rice is a staple food source for more than three billion people worldwide. However, rice is vulnerable to diseases, the most destructive among them being rice blast, which is caused by the fungus Magnaporthe oryzae (anamorph Pyricularia oryzae). This fungus attacks rice plants at all stages of development, causing annual losses of approximately 10-30% in various rice producing regions. Syntheti...
متن کاملBiochemical changes in rice plants due to application of bioinoculant, organic product, plant activator and moculation of Pyricularia oryzae
Rice continues to be the major staple food crop for human population. With the twin forces of population growth and economic expansion particularly in Asia, world rice requirements are expected to increase by 1.7 per cent annually between 1990 and 2025. Although seemingly small, this growth rate translates into an additional requirement of 13 million tonnes of rice per year. With less land avai...
متن کاملPathogenic Variation and Molecular Characterization of Pyricularia oryzae, Causal Agent of Rice Blast Disease in Tanzania
Rice blast disease, caused by the fungus Pyricularia oryzae, is one of the most devastating diseases of rice. Understanding pathogenic variation and molecular characterization of P. oryzae is one of the most efficient ways to manage the disease. Studies on identification, characterization and pathogenic variation of P. oryzae were conducted in the laboratory and screen-house at Sokoine Universi...
متن کاملFitness Characters in Parasexual Recombinants of the Rice Blast Fungus, Pyricularia oryzae
We examined the fitness characters in parasexual recombinants derived from cocultures of two isolates, NAO-02 (race 133.1) and TH77-1 (race 047.0), of the rice blast fungus, Pyricularia oryzae, in liquid yeast extract medium. The cocultured isolates were transferred to oatmeal agar to produce a conidial inoculum. Then, the conidial suspension was sprayed on the japonica rice cultivar Akiyutaka,...
متن کاملAcquired Tolerance to Blasticidin-S in Pyricularia oryzae
HWANG, B. K., and H. S. CHUNG. 1977. Acquired tolerance to Blasticidin-S in Pyricularia oryzae. Phytopathology 67: 421-424. Thirteen naturally-occurring isolates of Pyricularia oryzae transfers on fungicide-free media. Successive monoconidial varied in tolerance to Blasticidin-S [l-(1'-cytosinyl)-4-[L-3'cultures of Bu7 were genetically homogeneous for tolerance. amino-5-(l"-N-methylguanidino) v...
