Aggressiveness of Pseudocercospora griseola strains in common bean genotypes and implications for genetic improvement
Authors: R. Pereira, E.A. Souza, Q.L. Barcelos, A.F.B. Abreu and S.S. Librelon
The fungus Pseudocercospora griseola, the causal agent of angular leaf spot in the common bean (Phaseolus vulgaris L.), exhibits a broad pathogenic variability that complicates the development of resistant cultivars. For breeding programs to successfully obtain common bean cultivars with durable resistance, knowing the aggressiveness of different strains,.. Read More»

Acetobacter bacteria are found in Zhenjiang vinegar grains
Authors: C.Y. Wang, J. Zhang and Z.Z. Gui
Zhenjiang vinegar, the grains of which contain a unique microbial flora, is one of the four famous traditional Chinese vinegars. We investigated the components of Zhenjiang vinegar grains. Unique acetic acid bacteria were randomly isolated from Zhenjiang vinegar grains, and the obtained strains were qualitatively analyzed to compare their capacities for a.. Read More»

Distinct linear hydrocarbon profiles and chemical strategy of facultative parasitism among Mischocyttarus wasps
Authors: A.C. Ferreira C.A.L. Cardoso E.F. Neves Y.R. S�ºarez W.F. Antonialli-Junior
Insects use pheromones as a means of chemical communication. Pheromones act on individual receptors and produce specific behavioral or physiological responses that are fundamental to intra- and interspecific recognition. The objective of this study was to evaluate the interspecific differences among the linear hydrocarbon profiles of the cuticles of 3 wasp s.. Read More»

Microsatellite markers for Amazon pellona Pellona castelnaeana (Clupeiformes: Pristigasteridae)
Authors: A.M. Ximenes, E.J. Hern�¡ndez-Ruz, V.N. Machado, L.R.R. Rodrigues, G.C.S. Ritter and I.P. Farias
The Amazon pellona is one of the few species of Pristigasteridae with recognized commercial value in the Amazon. We isolated 24 and characterized 8 microsatellite loci for this species. The number of alleles ranges from 2-8 per locus. Observed heterozygosities ranged from 0.052-0.823, while expected heterozygosities from 0.052-0.836. These 8 microsatellit.. Read More»

Paracoccidioides brasiliensis RNA biogenesis apparatus revealed by functional genome analysis
Authors: PatrÃ?Âcia Albuquerque, Alessandra J. Baptista, Lorena da Silveira Derengowsky, Luciano ProcÃ?³pio, AndrÃ?© Moraes Nicola, FabrÃ?Âcio B.M. Arraes, Diorge Paulo de Souza, Cynthia Maria Kyaw and Ildinete Silva-Pereira
The RNA biogenesis machinery of Paracoccidioides brasiliensis was assessed by comparative analyses of PbAESTs (P. brasiliensis assembled expressed sequence tags (ESTs)) with sequences from Saccharomyces cerevisiae MIPS database. PbAESTs related to almost all categories of S. cerevisiae RNA biogenesis were found. Two of the 12 .. Read More»

General metabolism of the dimorphic and pathogenic fungus Paracoccidioides brasiliensis
Authors: FabrÃ?Âcio B.M. Arraes, Bruno Benoliel, Rafael T. Burtet, PatrÃ?Âcia L.N. Costa, Alexandro S. Galdino, Luanne H.A. Lima, Camila Marinho-Silva, Luciana Oliveira-Pereira, Pollyanna Pfrimer, Luciano ProcÃ?³pio-Silva, Viviane Castelo-Branco Reis and Maria Sueli S. Felipe
Annotation of the transcriptome of the dimorphic fungus Paracoccidioides brasiliensis has set the grounds for a global understanding of its metabolism in both mycelium and yeast forms. This fungus is able to use the main carbohydrate sources, including starch, and it can store reduced carbons in the form of glycogen and trehal.. Read More»

Paracoccidioides brasiliensis translation and protein fate machineries revealed by functional genome analysis
Authors: Diorge Paulo de Souza, Simoneide Souza Silva, Alessandra J. Baptista, Andr�© Moraes Nicola, Cynthia M. Kyaw and Ildinete Silva-Pereira
The translational and post-translational modification machineries of Paracoccidioides brasiliensis were assessed by means of comparative analyses of PbAESTs (P. brasiliensis assembled expressed sequence tags) with sequences deposited on different databases. Of the 79 sequences corresponding to cytosolic ribosomal proteins, we .. Read More»

Cell cycle, DNA replication, repair, and recombination in the dimorphic human pathogenic fungus Paracoccidioides brasiliensis
Authors: Viviane Castelo Branco Reis, Fernando Araripe GonÃ?§alves Torres, Marcio JosÃ?© PoÃ?§as-Fonseca, Marlene Teixeira De-Souza, Diorge Paulo de Souza, JoÃ?£o Ricardo Moreira Almeida, Camila Marinho-Silva, NÃ?¡dia Skorupa Parachin, Alessandra da Silva Dantas, Thiago Machado Mello-de-Sousa and LÃ?Âdia Maria Pepe de Moraes
DNA replication, together with repair mechanisms and cell cycle control, are the most important cellular processes necessary to maintain correct transfer of genetic information to the progeny. These processes are well conserved throughout the Eukarya, and the genes that are involved provide essential information for understand.. Read More»

Cell signaling pathways in Paracoccidioides brasiliensis - inferred from comparisons with other fungi
Authors: Larissa Fernandes, Marcus A.M. Ara�ºjo, Andr�© Amaral, Viviane Castelo Branco Reis, Nat�¡lia F. Martins and M.S. Felipe
The human fungal pathogen Paracoccidioides brasiliensis is an ascomycete that displays a temperature-dependent dimorphic transition, appearing as a mycelium at 22°C and as a yeast at 37°C, this latter being the virulent form. We report on the in silico search made of the P. brasiliensis transcriptome-expressed sequence.. Read More»

Paracoccidioides brasiliensis - Special Session
Authors: Maria Sueli Soares Felipe
Paracoccidioidomycosis (PCM) is the most important systemic mycosis in Brazil, and it is widespread throughout Latin America. An estimated 10 million individuals are infected, with about 2% developing the disease. This mycosis has also been reported among patients with AIDS in Latin America. PCM presents several clinical forms.. Read More»
