13. 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

14. RESPOSTA ESPECTRAL DE FOLHAS DE Eucalyptus globulus (Labill.) ATACADAS POR Mycosphaerella spp. / SPECTRAL RESPONSE OF Eucalyptus globulus (Labill.) LEAFS ATTACKED BY Mycosphaerella spp.
Eucalyptus globulus one of the most important species for paper and pulp industries, nowadays faces development problems in several countries due to its susceptibility to the fungus Mycosphaerella spp., which causes leaf spots that may cause the crown defoliation. The study aims at analyzing the spectral behavior of E. globulus leafs in response to the sever

15. 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

16. Variabilidad de Puccinia sorghi en la zona maicera núcleo Argentina
Common rust caused by Puccinia sorghi is one of the endemic diseases of corn in Argentina. It appears every year with different levels of severity depending on the genotype of the host, the biotypes of the pathogen, and the environmental conditions. Estimates of grain weight losses ranged from about 3 to 8% for 10% of the total leaf area affected. P. sorghi

17. Biphasic haustorial differentiation of coffee rust (Hemileia vastatrix race II) associated with defense responses in resistant and susceptible coffee cultivars.
The objective of this study was to assess whether defence responses in coffee (Coffea arabica) were linked to a specific developmental stage of the rust fungus Hemileia vastatrix. Histological observations in compatible and incompatible highyielding Brazilian coffee cultivars showed that the fungus produced ?pioneer? haustoria in adjacent and subsidiary stom

19. PredIP: an in silico approach for automated protein interaction prediction in genomic and transcriptomic sequence databanks.
The fast-growing amount of protein interaction databanks have made possible to analyze deeply several metabolic or signaling pathways in different organisms. The information available in such databanks can be used to predict new protein interactions in transcriptome or proteome sequences, most of times this task is done by sequence homology or by structure s

20. Uso de microorganismos promotores de crescimento como tecnologia para incrementar a produção de madeira e sequestro de carbono de Schizolobium amazonicum Huber ex Ducke (Paricá) em condições de campo
Schizolobium amazonicum Heber ex Ducke occurs naturally in Amazon and presents huge commercial importance due to its rapid growth and excellent performance on cropping systems a fact that has been raising much interest in the study of new strategies to increase more efficiently the wood yield. The use of soil microorganisms and its growth-promoting potent

21. The role of mycorrhization helper bacteria in the establishment and action of ectomycorrhizae associations
More than 95 % short roots of most terrestrial plants are colonized by mycorrhizal fungi as soon as they emerge in the upper soil profiles. The establishment of mycorrhizal association involves profound morphological and physiological changes in root and fungus. It is affected by other rhizospheric microorganisms, specifically by the bacteria. Bacteria may h

22. Biological activity of the mite Sancassania sp. (Acari: Acaridae) from bat guano associated with the pathogenic fungus Histoplasma capsulatum
Mites and the mammal pathogenic fungus Histoplasma capsulatum are the major components of bat guano microbiota. Interactions between mites and H. capsulatum were evaluated under laboratory conditions. Acarid mites, mainly Sancassania sp., were the most abundant microarthropod in the sampled guano of the Mexican bat Tadarida brasiliensis mexicana and, based o

23. Bacillus subtilis induces morphological changes in Fonsecaea pedrosoi in vitro resulting in more resistant fungal forms in vivo
Interactions among microorganisms may be the cause of morphological modifications, particularly in fungal cells. The aim of this work was to examine the changes that occur in cells of the fungus Fonsecaea pedrosoi after in vitro co-culturing with Bacillus subtilis and to explore the results of this interaction in vivo in an experimental murine infection.

24. Induction of apoptosis in A549 pulmonary cells by two Paracoccidioides brasiliensis samples
Paracoccidioidomycosis presents a variety of clinical manifestations and Paracoccidioides brasiliensis can reach many tissues, most importantly the lungs. The ability of the pathogen to interact with host surface structures is essential to its virulence. The interaction between P. brasiliensis and epithelial cells has been studied, with particular emphasis o
