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 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 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 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 کاملGenetic variation in resistance to blast disease (Pyricularia oryzae Cavara) in Japanese rice (Oryza sativa L.), as determined using a differential system
A total of 324 Japanese rice accessions, including landrace, improved, and weedy types were used to 1) investigate genetic variations in blast resistance to standard differential isolates, and 2) across the genome using polymorphism data on 64 SSR markers. From the polymorphism data, the accessions were classified into two clusters,. Accessions from irrigated lowland areas were included mainly ...
