1. Ephebe brasiliensis (Ascomycota, Lichinaceae): an overlooked freshwater lichenized fungus
Resumo Ephebe brasiliensis é um cianolíquen fruticoso e semiaquático que ocorre em ambientes de água doce do Brasil e Uruguai. Embora essa espécie possa ser localmente abundante e apresente uma ampla distribuição geográfica, ela ainda é pouco estudada e permanece incompreendida. Nesse artigo, E. brasiliensis é registrada pela primeira para o Sul do

2. Regulação da expressão gênica por oxigênio no fungo aquático Blastocladiella emersonii / Regulation of gene expression by oxygen in the aquatic fungus Blastocladiella emersonii
In this work we analyzed global gene expression changes in the aquatic fungus Blastocladiella emersonii submitted to oxygen deprivation (hypoxia), using cDNA microarrays containing 3,773 distinct genes. In gradual hypoxia (gradual decrease in dissolved oxygen concentration, followed by reoxygenation) and direct hypoxia (direct decrease of dissolved oxygen co

3. Globlal gene expression analysis during germination of the aquatic fungus Blastocladiella emersonii / Análise da expressão gênica global durante a germinação do fungo aquático Blastocladiella emersonii
We conducted large scale cDNA sequencing from libraries obtained using RNA from germinating cells of the aquatic fungus Blastocladiella emersonii. Data obtained in this work, along with cDNAs from sporulating cells, lead to the discovery of nearly 4.900 different genes from B. emersonii (Ribichich et al., 2005). The putative genes were annotated and associat

4. Analysis of gene expression in response to cadmium and heat shock in the aquatic fungus Blastocladiella emersonii / Análise da expressão gênica em resposta ao choque térmico e cádmio no fungo aquático Blastocladiella emersonii
In this work we realized a large scale, sequencing program of cDNAs libraries obtained from mRNA of B. emersonii cells submitted to heat shock and cadmium stress. A total of 6350 high quality expressed sequence tags (ESTs) were obtained, representing 2326 unique putative genes (unigenes) of this fungus. From these putative unigenes, 1282 genes were classifie

5. Expressão gênica diferencial durante o desenvolvimento e na resposta ao choque térmico em Blastocladiella emersonii / Differential gene expression during development and in the heat shock response in Blastocladiella emersonii
Usando incorporação \"in vivo\" de 35S metionina tradução \"in vitro\" de RNA e eletroforese bidimensional, iniciamos um estudo do controle da síntese de proteínas durante duas fases distintas de diferenciação celular, a esporulação e a germinação, do fungo Blastocladiella emersonii. Durante a esporulação ocorre uma intensa variação no padrã

6. Characterization and Submitochondrial Localization of the α Subunit of the Mitochondrial Processing Peptidase from the Aquatic Fungus Blastocladiella emersonii
In an effort to investigate the molecular mechanisms responsible for the drastic morphological changes the mitochondria go through during the life cycle of the aquatic fungus Blastocladiella emersonii, the gene encoding the α subunit of the mitochondrial processing peptidase (α-MPP) was isolated. Nucleotide sequence analysis revealed that the predicted α-

7. In Vitro Ribonucleic Acid Synthesis in the Zoospores of the Aquatic Fungus Blastocladiella emersonii
The zoospores of Blastocladiella emersonii posses three ribonucleic acid polymerases. No general or specific inhibitor for the enzymes were found in the protoplasm of the spores.

8. Novel Ca2+-activated neutral protease from an aquatic fungus, Allomyces arbuscula.
A Ca2+-activated neutral protease was purified to homogeneity from an aquatic Phycomycete fungus, Allomyces arbuscula. It requires millimolar concentrations of Ca2+ for activation (1.8 to 2 mM for 50% activation). Sr2+ can replace Ca2+ but at higher concentrations (4 mM for 50% activation). The enzyme is a dimer of 40-kilodalton subunits and contains six cys

9. Colonization of a Submersed Aquatic Plant, Eurasian Water Milfoil (Myriophyllum spicatum), by Fungi under Controlled Conditions
A laboratory assay to assess colonization of a submersed aquatic plant, Eurasian water milfoil (Myriophyllum spicatum), by fungi was developed and used to evaluate the colonization potential of Colletotrichum gloeosporioides, Acremonium curvulum, Cladosporium herbarum, Aureobasidium pullulans, a Paecilomyces sp., and an unidentified sterile, septate fungus.

10. Interactions Between DDT and River Fungi: I. Effects of p,p′-DDT on the Growth of Aquatic Hyphomycetes
Concentrations of p,p′-DDT between 0.1 and 60 μg/ml enhanced the growth rate of Heliscus submersus, and concentrations greater than 2 μg/ml had a similar effect on Tetracladium setigerum, Varicosporium elodeae, and Clavariopsis aquatica. The rate of growth of each fungus increased with increased DDT concentration.

11. Selective Medium for Isolation of Mycoleptodiscus terrestris from Soil Sediments of Aquatic Environments
A selective medium was developed for the dilution plate isolation of Mycoleptodiscus terrestris from natural soils and sediments from aquatic environments. The ingredients per liter of the selective medium are as follows: KH2PO4, 0.5 g; MgSO4 7H2O, 0.5 g; dextrose, 10.0 g; peptone, 5.0 g; chloramphenicol, 0.25 g; rose bengal, 50 mg; oxgall, 5.0 g; Terraclor
