Cytological aspects of incompatible and compatible interactions between rice, wheat and the blast pathogen Pyricularia oryzae Scientia Agricola
Araujo,Leonardo; Soares,Juliana Moreira; Filippi,Marta Cristina Corsi de; Rodrigues,Fabrício Ávila.
ABSTRACT Blast, caused by the fungus Pyricularia oryzae, is an important disease affecting rice and wheat yield worldwide. This study investigated the cytological aspects of incompatible (non-host resistance) and compatible (host resistance) rice- (R_Po) and wheat- (W_Po) Pyricularia oryzae isolate interactions. Inoculations of rice and wheat with the R_Po and W_Po isolates of P. oryzae, respectively, were expected to be compatible interactions (host resistance), whereas inoculations of rice and wheat with the W_Po and R_Po isolates of P. oryzae, respectively, were considered to be incompatible interactions (non-host resistance). For the compatible interactions (rice-R_Po and wheat-W_Po), fungal hyphae penetrated and colonized the epidermal cells and also...

Resistance to triazole fungicides in Pyricularia species associated with invasive plants from wheat fields in Brazil Agronomy
Dorigan, Adriano Francis; Carvalho, Giselle de; Poloni, Nadia Maria; Negrisoli, Matheus Mereb; Maciel, João Leodato Nunes; Ceresini, Paulo Cezar.
Triazole fungicides have not been effective for managing the wheat blast disease in Brazil. A broad analysis across six geographical populations of Pyricularia graminis-tritici in central-southern Brazil indicated a high level of resistance to triazole fungicides. Since P. graminis-tritici is also associated with others poaceous species, here, we analyzed whether triazole-resistant isolates of the blast pathogen could be recovered from other poaceous hosts that are invasive of sprayed wheat fields. In addition to P. graminis-tritici (Pygt), we also evaluated the levels of sensitivity of three other grass-associated blast pathogens, which included P. grisea (Pg), P. pennisetigena (Pp), and P. urashimae (Pu). Resistance to the triazole fungicides...
