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 کاملGenetic variation in resistance to blast (Pyricularia oryzae Cavara) in rice (Oryza sativa L.) germplasms of Bangladesh
Genetic variation in blast resistance was clarified in 334 Bangladesh rice accessions from 4 major ecotypes (Aus, Aman, Boro and Jhum). Cluster analysis of polymorphism data of 74 SSR markers separated these accessions into cluster I (corresponding to the Japonica Group) and cluster II (corresponding to the Indica Group). Cluster II accessions were represented with high frequency in all ecotype...
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 کاملComparative analyses of genomic locations and race specificities of loci for quantitative resistance to Pyricularia grisea in rice and barley.
Comparative genomic analyses have revealed extensive colinearity in gene orders in distantly related taxa in mammals and grasses, which opened new horizons for evolutionary study. The objective of our study was to assess syntenic relationships of quantitative trait loci (QTL) for disease resistance in cereals by using a model system in which rice and barley were used as the hosts and the blast ...
متن کاملA cross-resistance of Pyricularia oryzae Cavara to kasugamycin and blasticidin S.
A cross resistance of pathogenic organisms to various chemicals has been increasing over a long period of time causing serious problems in the field of antibacterial drugs and veterinary drugs. Recently, it was reported that some phytopathogenic bacteria and fungi resistant to antibiotics and synthetic fungicides were isolated from diseased plants in the field and that distribution of resistant...
