Biochemical 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 کاملThe 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 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...
