Pyricularia oryzae: Lab star and field scourge [PDF]

Molecular Plant Pathology, Volume 25, Issue 4, April 2024.
The fungal pathogen Pyricularia oryzae (syn. Magnaporthe oryzae) is the causal agent of blast disease on cereals and grasses and a model organism in plant–pathogen interaction research. Abstract Pyricularia oryzae (syn. Magnaporthe oryzae), is a filamentous ascomycete that causes a major disease called blast on cereal crops, as well as on a wide ...

IDENTIFICATION OF NON-PATHOGENIC FUNGI OF RICE AND THE EVALUATION OF THEIR EFFECT ON BIOLOGICAL CONTROL OF Pyricularia grisea, THE CAUSAL AGENT OF RICE BLAST DISEASE in vitro

Acta Scientiarum Polonorum: Hortorum Cultus, 2016
Rice blast disease, caused by Pyricularia grisea, is an important rice disease in Iran and throughout the world. Out of 150 infected samples collected from paddy fields of Guilan province, 57 fungal isolates were isolated for which PDA and W.A media ...

Expression of resistance in rice hybrids to Pyricularia grisea [PDF]

Fitopatologia Brasileira, 2002
Thirty-nine rice (Oryza sativa) hybrids and their restorers were assessed for vertical resistance to Pyricularia grisea in the rice blast nursery, and in artificial inoculation tests with two pathotypes, under controlled greenhouse conditions. The hybrids were developed from cytoplasmic genetic male sterile lines 046I and IR 58025A, derived from WA ...

Eficiência da disseminação aérea em Pyricularia grisea [PDF]

Summa Phytopathologica, 2007
Pyricularia grisea (teleomorfa Magnaporthe grisea) é um patógeno que infecta mais de 80 gramíneas. No Brasil ataca importantes culturas como arroz e trigo, causando a brusone. Mais recentemente foi reportada na triticale, cultura alternativa para os produtores de trigo no sul do estado de São Paulo. Um dos principais meios de disseminação da doença é a

Pathotypes of Pyricularia grisea in Rice Fields of Central and Southern China [PDF]

Plant Disease, 2001
Blast, caused by the fungal pathogen Pyricularia grisea, is the most devastating disease of rice worldwide. Knowledge of the pathotype composition of the pathogen in rice fields is essential for rational deployment of resistance genes in rice breeding programs. In this study, we assayed the pathotypes of the pathogen populations using samples recently
