1. SURE e Garapa: caracterização molecular e distribuição de dois retrotransposons com LTR em cana-de-açúcar. / SURE and Garapa: molecular characterization and distribution of two LTR retrotransposons in sugarcane.
O objetivo deste trabalho foi caracterizar uma nova família de retrotransposons Copia em cana-de-açúcar, e também compreender a diversidade de retrotransposons com LTR transcricionalmente ativos em cana, com base na análise filogenética de cDNAs provenientes do projeto SUCEST. Foi assim isolada uma nova família de retrotransposons de cana, denominada

2. Identificação de genes associados a produção de ocratoxina A em Aspergillus westerdijkiae
Mycotoxins, secondary metabolites of fungi, are toxic compounds found in great variety of foods, and when ingested can be very hazardous to animal and human health. Among the diverse mycotoxins, special interest has been given to the ochratoxin A (OA), produced by some species of Aspergillus and Penicillium. This mycotoxin is frequently found mainly in food

3. Estudo in silico de genes que codificam fatores de transcriÃÃo responsivos Ãseca, salinidade e congelamento nos genomas do eucalipto, cana e arroz
Abiotic stresses are the most responsable for causing changes in plant growth and development. The plants, in counterpart, make use of a variety of responses in order to maintain their metabolic and physiological processes. One of the main plants responses to environmental conditions alterations is the additional regulation of expression. Moreover, the biosy

4. Intergenic Transcription in the Human β-Globin Gene Cluster
Our previous studies on nascent transcription across the human β-globin gene cluster revealed the presence of intergenic transcripts in addition to the expected genic transcripts. We now show that transcription into the β-globin locus control region (LCR) begins within an ERV9 endogenous retroviral long terminal repeat upstream of DNase I hypersensitive si

5. Genic and Allelic Interactions in the Carotenogenic Response of Myxococcus Xanthus to Blue Light
In the bacterium Myxococcus xanthus, the synthesis of carotenoids requires illumination with blue light. This stimulates transcription of the carB locus, which is positively required for carotenogenesis. Mutations at the carR locus and the only mutation known at carA cause constitutive expression of carB and thus remove the light requirement for carotenoid a

6. Activation of MEF2 by muscle activity is mediated through a calcineurin-dependent pathway
Gene expression in skeletal muscles of adult vertebrates is altered profoundly by changing patterns of contractile work. Here we observed that the functional activity of MEF2 transcription factors is stimulated by sustained periods of endurance exercise or motor nerve pacing, as assessed by expression in trans genic mice of a MEF2-dependent reporter gene (de

7. The Genexpress IMAGE Knowledge Base of the Human Brain Transcriptome: A Prototype Integrated Resource for Functional and Computational Genomics
Expression profiles of 5058 human gene transcripts represented by an array of 7451 clones from the first IMAGE Consortium cDNA library from infant brain have been collected by semiquantitative hybridization of the array with complex probes derived by reverse transcription of mRNA from brain and five other human tissues. Twenty-one percent of the clones corre

8. Dedifferentiation of Tobacco Cells Is Associated with Ribosomal RNA Gene Hypomethylation, Increased Transcription, and Chromatin Alterations1[w]
Epigenetic changes accompanying plant cell dedifferentiation and differentiation are reported in 35S ribosomal DNA (rDNA) of tobacco (Nicotiana tabacum). There was a reduction of CG and CNG methylation in both intergenic and genic regions of the rDNA cistron in fully dedifferentiated callus and root compared to leaf. The rDNA hypomethylation was not random,

9. Genes encoding a subunit of respiratory NADH dehydrogenase (ND1) and a reverse transcriptase-like protein (RTL) are linked to ribosomal RNA gene pieces in Chlamydomonas reinhardtii mitochondrial DNA.
Two long and uninterrupted reading frames, specifying the ND1 and RTL genes, are embedded within fragmented rRNA genes in the 15.8-kb mitochondrial genome of Chlamydomonas reinhardtii, a unicellular green alga. The ND1 gene encodes a subunit of respiratory NADH dehydrogenase, a standard mitochondrial gene, while the RTL gene is related to the reverse transcr
