Bayesian factorial design as a tool in the identification of rice blast resistance sources. Repositório Alice
MELLO, R. N.; MORAIS JUNIOR, O. P.; ABREU, A. G.; BORBA, T. C. O..
Rice germplasm banks have many promising sources of resistance to pathogens. However, identification of resistant genotypes is often arduous, notably when the host-pathogen relationship is complex as in rice blast. In addition, selection of representative Magnaporthe oryzae isolates to adequately identify sources of broad-spectrum resistance is challenging. To overcome these obstacles, data from pathogenicity assays were analyzed as a factorial design, where the pairwise combination comprised rice genotypes and blast isolates. Using this methodology, we aimed to access information about host resistance.

Cladosporium cladosporioides C24G modulates gene expression and enzymatic activity during leaf blast suppression in rice plants. Repositório Alice
CHAIBUB, A. A.; SOUSA, T. P. de; ARAÚJO, L. G. de; FILIPPI, M. C. C. de..
The inclusion of biological control in the integrated management of rice blast (Magnaporthe oryzae) is an alternative to reduce pesticides application. C24G, classified, as Cladosporium cladosporioides was isolated from the phylloplane of the rice plant, therefore, adapted to natural conditions of the original habitat. This study aimed to compare four application methods of C24G in rice plants to suppress leaf blast together with the increase in enzymatic activity and expression of defense genes. It was conducted by four assays (1: seed and soil, 2: soil drenching, 3: foliar spray pulverization-preventive and 4: foliar spray pulverization-curative) for choosing the best application method. The best methods identified were further investigated for the...

Cytological aspects of incompatible and compatible interactions between rice, wheat and the blast pathogen Pyricularia oryzae. Repositório Alice
ARAUJO, L.; SOARES, J. M.; FILIPPI, M. C. C. de; RODRIGUES, F. A..
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 invaded...

Elevated atmospheric CO2 concentration increases rice blast severity. Repositório Alice
GÓRIA, M. M.; GHINI, R.; BETTIOL, W..
Abstract: The predicted atmospheric carbon dioxide concentration?s increases are likely to alter plant-pathogen interactions. To assess the effects on rice blast, during three years (2007, 2008 and 2009), three rice cultivars (Agulha Precoce, Shao Tiao Tsao and Caloro) were exposed to elevated CO2 air concentration (approximately 100 - 300 ?mol mol-1 higher than ambient) in open-top chamber facility. The disease was more severe under high CO2 concentration. Area under disease progress curve was 35.43 under high CO2 concentration and 17.48 for the current concentration. Leaves of treated plants tended to contain less silicon. In 2009, plant height of two cultivars was greater in high CO2. Understanding and predicting the climate-driven changes in the...

Genetic structure and mating type analysis of the Pyricularia oryzae population causing widespread epidemics in southern Brazil. Repositório Alice
D'ÁVILA, L. S.; LEHNER, M. S.; FILIPPI, M. C. C.; SCHEUERMANN, K. K.; DEL PONTE, E. M..
Blast is a major disease of rice in Brazil, the largest rice-producing country outside Asia. This study aimed to assess the genetic structure and mating-type frequency in a contemporary Pyricularia oryzae population, which caused widespread epidemics during the 2012/13 season in the Brazilian lowland subtropical region. Symptomatic leaves and panicles were sampled at flooded rice fields in the states of Rio Grande do Sul (RS, 34 fields) and Santa Catarina (SC, 21 fields). The polymorphism at ten simple sequence repeats (SSR or microsatellite) loci and the presence of MAT1-1 or MAT1-2 idiomorphs were assessed in a population comprised of 187 isolates. Only the MAT1-2 idiomorph was found and 162 genotypes were identified by the SSR analysis. A discriminant...
