A 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...
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 ...
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 کاملAsperfuran, a novel antifungal metabolite from Aspergillus oryzae.
Asperfuran is a novel antifungal dihydrobenzofuran derivative produced by a strain of Aspergillus oryzae. Asperfuran weakly inhibited chitin synthase from Coprinus cinereus. This inhibition could be abolished by the addition of egg lecithin. In the agar diffusion assay asperfuran induced morphological changes in Mucor miehei at very low concentrations (20 ng/disc) while growth was only partly i...
