Characterization of Magnaporthe grisea (Pyricularia grisea) from Black Oat in Brazil
Journal of Phytopathology, 2011AbstractBlast caused by Magnaporthe grisea (Pyricularia grisea) is a disease that occurs in many important gramineous plants in Brazil such as rice, wheat, triticale and barley. In 2005, the presence of this disease was reported on black oat (Avena strigosa) at different locations of Parana state. Due to little information of M.

Phytotoxins from Pyricularia grisea and Their Effect on Finger Millet
Journal of Plant Biochemistry and Biotechnology, 2006Pyricularia grisea, the fungus that causes blast disease in finger millet [Eleusine coracana (L) Gaertn] produced maximum quantity of crude toxins. Crude toxins were partially purified and characterized by UV and mass spectra. Pyrichalasin H, a phytotoxic metabolite, has been identified and found to be toxic when tested for inhibition of seed ...

Spore Dispersal in Pyricularia grisea (Cooke) Sacc.
Nature, 1962Pyricularia grisea is probably best known in relation to ‘blast’ disease of rice. Some workers have considered this fungus to be the causal organism, but others ascribe the disease to a distinct species. P. oryzae Cav.1. P. grisea is associated with ‘pitting’ disease of Cavendish bananas in Brazil, Trinidad and Australia2–6. Pitting is commonest on the

Monoclonal antibodies to an extracellular component of Pyricularia grisea
Canadian Journal of Botany, 1992Monoclonal antibodies were produced from fusions of myeloma cells with splenocytes from BALB/c mice immunized with an extract of a liquid culture fluid of an isolate of Pyricularia grisea race IB—49. The hybridomas were screened with the immunogen, and three were selected and propagated in mice for antibodies in ascites fluid.

Cross-Incompatibility Among Indian Isolates ofPyricularia grisea
Plant Disease, 1995There have been few investigations into the occurrence of the perfect state of Pyricularia grisea in India. We collected isolates of the fungus from several native cereal and grass hosts. We made 756 crosses among 172 monoconidial isolates from these collections of P. grisea.

[Effects of ecological factors on infection process of Pyricularia grisea].
Ying yong sheng tai xue bao = The journal of applied ecology, 2002Rice blast is one of the main rice diseases. In order to discuss the occurrence regularity and improve the veracity of forecasting, the effects of ecological factors on infecting process, such as rice growth period, cultivar resistance, temperature, precipitation, and fertilization of nitrogen, were studied quantitatively.

Genetic Structure of Pyricularia grisea (Cooke) Sacc. Isolates from Italian Paddy Fields
Journal of Phytopathology, 2005AbstractRice blast disease, caused by the fungus Pyricularia grisea (Cooke) Sacc., is responsible for considerable damages in rice crops in Italy and in other parts of the world. This study was conducted in order to investigate the genetic structure of a P. grisea population in the Po area, the largest rice area in Italy.

Abstract Appressorial penetration of onion epidermal walls by wild-type strains P-2 and O-42 of Pyricularia oryzae was more sensitive to fthalide (4,5,6,7-tetrachlorophthalide) than penetration by wildtype strain 4091-5-8 and black mutant strain BL-3 of Pyricularia grisea. Cerulenin completely blocked appressorial penetration by P.
