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 ...

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.

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.

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

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.

[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.

The Relationship Between Lineage and Virulence inPyricularia griseain the Philippines
Phytopathology, 1995The relationship between phylogeny and pathotype was examined for a selected group of isolates of the blast fungus Pyricularia grisea from two sites in the Philippines. Based on DNA fingerprinting and cluster analysis with the repetitive DNA probe MGR586, isolates fell into several distinct groups.

[Relationship between genetic lineage and pathotype of Pyricularia grisea in Yunnan Plateau].
Yi chuan xue bao = Acta genetica Sinica, 2004Rice blast caused by Pyricularia grisea is the most destructive disease in Yunnan Plateau, China. In order to elucidate the relationship between genetic lineage and pathotype of P. grisea of Yunnan Plateau as well as the variability of the fungus at DNA level,the repetitive element-based PCR (rep-PCR) of Pot2, an element found in approximately 100 ...
