Provedor de dados: Genetics and Molecular Biology
Autores: Saccuti,Cecília Ferreira; Soares,Maria Albertina de Miranda; Falco,José Ricardo Penteado; Fernandez,Maria Aparecida.
We determined the genome size of the Brazilian sciarid flies Bradysia hygida, Rhynchosciara americana and Trichosia pubescens (Diptera: Sciaridae) using absorbance measurements of Feulgen-stained nuclei belonging to these species (and chicken erythrocytes as a standard) to calculate the amount of DNA in picograms (pg) and the number of base pairs (bp), or C-value, for each of these species. The C-values were: 3 x 10(8) bp (0.31 pg) for B. hygida; 3.6 x 10(8) bp (0.37 pg) for R. americana; and 1 x 10(9) bp (1.03 pg) for T. pubescens. The sciarids investigated in this work had considerably higher C-values than the average for previously described dipteran species, including D. melanogaster.

The histone genes cluster in Rhynchosciara americana and its transcription profile in salivary glands during larval development
Provedor de dados: Genetics and Molecular Biology
Autores: Siviero,Fábio; Rezende-Teixeira,Paula; Andrade,Alexandre de; Santelli,Roberto Vicente; Machado-Santelli,Glaucia Maria.
Abstract In this work we report the characterization of the Rhynchosciara americana histone genes cluster nucleotide sequence. It spans 5,131 bp and contains the four core histones and the linker histone H1. Putative control elements were detected. We also determined the copy number of the tandem repeat unit through quantitative PCR, as well as the unequivocal chromosome location of this unique locus in chromosome A band 13. The data were compared with histone clusters from the genus Drosophila, which are the closest known homologues.

Montagem de lâminas permanentes de Sciaridae da coleção Embrapa Florestas.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: CRUZ, P. C. da; SCHUHLI, G. S. e; QUEIROZ, D. L. de.
Lâminas de microscopia são usadas para diversos propósitos na entomologia, entre os mais importantes estão a identificação e preservação de material. Estas coleções também fundamentam a descrição de novas espécies, conservando tipos de descrições (holótipos, lectótipos e neótipos). São novos atributos desta proposta para o estudo da família Sciaridae tanto o uso do ácido lático, quanto do linoneno como solvente.

A new name for the Neotropical genus Aniarella Enderlein (Diptera, Sciaridae)
Provedor de dados: Revista Brasileira de Entomologia
Autores: Özdikmen,Hüseyin; Başar,Kadir.
A new name for the Neotropical genus Aniarella Enderlein (Diptera, Sciaridae). A junior homonym was detected among neotropical sciarid flies genera and the following replacement name is proposed: Novaniarella nom. nov. for Aniarella Enderlein, 1911 (nec Bolivar, 1906). Accordingly, new combinations are herein proposed for the species currently included in this genus: Novaniarella azteca (Lane, 1959) comb. nov., Novaniarella brevis (Rubsaamen, 1894) comb. nov. and Novaniarella pelluscens (Enderlein, 1911) comb. nov.

Aspectos alimentares e de criação de Bradysia hygida Sauaia &amp;amp; Alves (Diptera, Sciaridae) em laboratório
Provedor de dados: Zoologia
Autores: Bravo,Iara S. Joachim; Alves,Maurílio A. R; Zucoloto,Fernando S; Andrade,Luiz A. M.
In nature, the Sciaridae live in moist and shady places, where exists vegetable material in decomposition. It is very dificult to determine the proper Sciaridae's alimentary habit and then, it is dificult, also, to rear Sciaridae species in laboratory. To improvement the Bradysia hygida rearing, the objectives of this research were to analyse the nutritive value of mucuna bean foliage for the larves, to verify the role of the ground (as larvae substrate and in diet composition) and also to verify the possibility of ground substituition by another kind of substrate. Two kinds of sand were employed in the place of the ground and three diets, free of ground, were prepared. The parameters analysed were: duration of the life cicle, porcentage of emergence, egg...

5-Bromo-2’-deoxyuridine induces visible morphological alteration in the DNA puffs of the anterior salivary gland region of Bradysia hygida (Diptera, Sciaridae)
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: de Almeida,J.C.; Sauaia,H.; Viana,J.C.
5-Bromo-2’-deoxyuridine (BrdUrd) has long been known to interfere with cell differentiation. We found that treatment ofBradysia hygida larvae with BrdUrd during DNA puff anlage formation in the polytene chromosomes of the salivary gland S1 region noticeably affects anlage morphology. However, it does not affect subsequent metamorphosis to the adult stage. The chromatin of the chromosomal sites that would normally form DNA puffs remains very compact and DNA puff expansion does not occur with administration of 4 to 8 mM BrdUrd. Injection of BrdUrd at different ages provoked a gradient of compaction of the DNA puff chromatin, leading to the formation of very small to almost normal puffs. By immunodetection, we show that the analogue is preferentially...

Bradysia hygida (Diptera, Sciaridae) presents two eukaryotic Elongation Factor 1A gene homologues: partial characterization of the eukaryotic Elongation Factor 1A-F1 gene
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Candido-Silva,J.A.; Monesi,N.
Elongation factor 1A is a highly conserved protein that participates in translation. We report the occurrence of two genes homologous to the eukaryotic Elongation Factor 1A in Bradysia hygida and describe the partial cloning and characterization of the B. hygida eukaryotic Elongation Factor 1A-F1 (BheEF1A-F1) gene. The pattern of BheEF1A-F1 expression in the salivary gland at the end of the fourth larval instar was investigated using real-time PCR. The results showed that BheEF1A-F1 expression levels are relatively constant at the time when rapid changes in protein synthesis occur in this tissue. In situ hybridization experiments coupled to Southern blot analyses showed that the BheEF1A-F1 gene is located at position 3d of the A chromosome and a second...
