25. Identification of the soybean HyPRP family and specific gene response to Asian soybean rust disease
Soybean [Glycine max (L.) Merril], one of the most important crop species in the world, is very susceptible to abiotic and biotic stress. Soybean plants have developed a variety of molecular mechanisms that help them survive stressful conditions. Hybrid proline-rich proteins (HyPRPs) constitute a family of cell-wall proteins with a variable N-terminal domain

26. Evaluation of sugarcane introgression lines for resistance to brown rust disease caused by Puccinia melanocephala
Sugarcane brown rust disease caused by Puccinia melanocephala is one of the important fungal diseases affecting sugarcane yield around the world. Cultivar resistance is the most appropriate control method for this disease. In this study, 62 introgression lines chosen from the crossing Saccharum officinarum L. cv. Ludashi x Erianthus rockii Yunnan 95-19 were

27. Rust resistance in Arabic Coffee cultivars in northern Paraná
The objective of the study was to evaluate the resistance to rust in coffee cultivars developed by research institutes of Brazil in Paraná state. Resistance to the local leaf rust races was assessed in high disease intensity field conditions at Londrina and Congonhinhas in 2009 and 2010.The cultivars were developed by the EPAMIG/UFV, IAPAR, IAC and MAPA/Pro

28. Estabelecimento de um patossistema modelo e análise da interação molecular planta-patógeno entre Eucalyptus grandis e Puccinia psidii Winter por meio da técnica de RNA-Seq. / Establishment of a model pathosystem and analysis of the molecular plant-pathogen interaction between Eucalyptus grandis and Puccinia psidii Winter
More than 20 million hectares are destined to Eucalyptus plantations worldwide and Brazil has the second largest planted area. The International Eucalyptus Genome Network, EUCAGEN, was created in 2007 in order to perform genomic research on Eucalyptus. Brazil provided the biological material from the model tree (Brasuz) to have the complete genome sequenced

29. PROGRESSO DE Phakopsora pachyrhizi EM FUNÇÃO DO ESTÁDIO FENOLÓGICO E DA IDADE DE TRIFÓLIOS EM SOJA / PROGRESS OF Phakopsora pachyrhizi RELATED TO THE SOYBEANS PHENOLOGICAL STAGE AND LEAFLETS AGE
O uso de fungicidas com diferentes mecanismos de ação, assim como a época de aplicação dos mesmos, são fatores que devem ser levados em consideração para o controle da ferrugem asiática na soja. Uma vez que muitos produtos têm apresentado perda de eficiência, surge a necessidade de novas alternativas de controle dessa doença. Com este trabalho bu

30. Additional physiological races of coffee leaf rust (Hemileia vastatrix) identified in Kenya
Coffee leaf rust (CLR), caused by the fungus Hemileia vastatrix, is among the most important diseases affecting coffee all over the world. In Kenya, it is currently the second most important disease, and breeding coffee to obtain new resistant cultivars has been a priority. Over time, new rust pathogenic races able to infect hitherto resistant coffee genotyp

31. Epidemiologia e resistência do cafeeiro conilon à ferrugem / Epidemiology and resistance of coffee conilon to rust
Nos últimos anos a ferrugem no cafeeiro conilon (Coffea canephora), causada por Hemileia vastatrix, tem ocorrido no campo sob grandes epidemias. Pouco se conhece sobre esse patossistema e a partir de questionamentos sobre o hospedeiro, o patógeno e o ambiente dessa interação surgiu o interesse em desenvolver este trabalho, que teve como objetivos: 1) det

32. Resistência de híbridos de Coffea canephora Pierre ex Froehner às raças II e XXXIII de Hemileia vastatrix Berk. et Br / Resistance of Coffea canephora Pierre ex Froehner hybrids to races II and XXXIII of Hemileia vastatrix Berk. et Br
O café é um dos principais produtos comercializados no mundo e possui, historicamente, uma grande importância para a agricultura brasileira. Em 2011, estimase no Brasil a produção de 43,54 milhões de sacas beneficiadas de café, sendo o café conilon (Coffea canephora Pierre ex Froehner), responsável por aproximadamente 26,1% deste montante. A ferruge

33. Identificação e caracterização de genes que codificam proteínas secretadas por Hemileia vastatrix na interação com o cafeeiro / Identification and characterization of genes encoding proteins secreted by Hemileia vastatrix during interaction with coffee
The coffee leaf rust caused by the biotrophic fungus Hemileia vastatrix, it is the most important fungal disease of coffee, causing productivity losses and its control increases the costs of coffee production. This study aimed to identify genes of H. vastatrix that encode secreted proteins that may function as effectors needed for the establishment of the bi

34. Identification of SSR markers linked to rust resistance in andean common bean PI 260418.
The objective of this study was to identify molecular markers linked to the rust resistance gene or genes present in PI 260418. These markers will be very useful in the introgression of this new resistance into dry and snap bean cultivars.

35. Inheritance of coffee leaf rust reistance and identification of AFLP markers linked to the resistance gene.
The most important disease of Coffea arabica is coffee leaf rust caused by the fungus Hemileia vastatrix. The purpose of this study was to characterize the inheritance of coffee resistance gene(s) to race II of this pathogen and to identify and map molecular markers linked to this trait. Different populations were used: F2 (160 plants), BCr (20), and BCs (13
