Development of a warning system for wheat blast caused by Pyricularia grisea [PDF]

Summa Phytopathologica, 2008
Wheat (Triticum aestivum L.) blast caused by Pyricularia grisea is a new disease in Brazil and no resistant cultivars are available. The interactions between temperature and wetness durations have been used in many early warning systems. Hence, growth chamber experiments to assess the effect of different temperatures (10, 15, 20, 25, 30 and 35ºC) and ...

Reação de acessos de Cenchrus a Pyricularia grisea no semiárido brasileiro

Journal of Environmental Analysis and Progress, 2021
O fungo Pyricularia grisea causa manchas foliares em capim buffel (Cenchrus ciliaris), sendo um problema em pastagens dessa forragem no Texas, EUA e México. Apesar desta doença não apresentar problemas graves ao capim buffel no Semiárido brasileiro, a busca de germoplasma com algum nível de tolerância a esta doença tem importância preventiva.

Gain of Virulence Caused by Insertion of a Pot3 Transposon in a Magnaporthe grisea Avirulence Gene

Molecular Plant-Microbe Interactions, 2001
The avirulence gene AVR-Pita in Magnaporthe grisea prevents the fungus from infecting rice cultivars carrying the disease resistance gene Pi-ta. Insertion of Pot3 transposon into the promoter of AVR-Pita caused the gain of virulence toward Yashiro-mochi,
