Aspectos alimentares e de criação de Bradysia hygida Sauaia & Alves (Diptera, Sciaridae) em laboratório
(Sociedade Brasileira de Zoologia, 1993)
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 ...
Bradysia aliciae sp. nov. (Diptera: Sciaridae) del Pleistoceno de Buenos Aires, Argentina.Bradysia aliciae sp. nov. (Diptera: Sciaridae) from the Pleistocene of Buenos Aires, Argentina
(Sociedad Entomológica Argentina, 2014-06)
Bradysia aliciae sp. nov .(Diptera: Sciaridae) es descripta a partir de un ala con un excepcional estado de preservación proveniente del afloramiento de Camet Norte en Buenos Aires, Argentina, con una antigüedad de 24500 ...
Mariner-like elements in Rhynchosciara americana (Sciaridae) genome: molecular and cytological aspects
(SPRINGER, 2008)
Two mariner-like elements, Ramar1 and Ramar2, are described in the genome of Rhynchosciara americana, whose nucleotide consensus sequences were derived from multiple defective copies containing deletions, frame shifts and ...
The DNA puff 4C expresses a salivary secretion protein in Trichosia pubescens (Diptera; Sciaridae)
(WILEY-LISS, 2008)
DNA puffs are genomic regions of polytene chromosomes that undergo developmentally controlled DNA amplification and transcription in salivary glands of sciarid flies. Here, we tested the hypothesis that DNA puff genes code ...
Fisiología cromosómica, síntesis de proteínas y ácido ribonucléico en las glándulas salivares de Rhynchosciara Millery Diptera (Sciaridae).
(2013-06-28)
Se han estudiado algunas características citológicas y bioquímicas delas glándulas salivares de R. millery. entre los parámetros escogidos para la realización de este trabajo se consideraron: Eventos de apertura y cierre ...
Bradysia hygida (Diptera, Sciaridae) presents two eukaryotic Elongation Factor 1A gene homologues: partial characterization of the eukaryotic Elongation Factor 1A-F1 gene
(Associação Brasileira de Divulgação Científica, 2010)
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 ...
5-Bromo-2'-deoxyuridine induces visible morphological alteration in the DNA puffs of the anterior salivary gland region of Bradysia hygida (Diptera, Sciaridae)
(Associação Brasileira de Divulgação Científica, 2010)
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 ...
Indirect immune detection of ecdysone receptor (EcR) during the formation of DNA puffs in Bradysia hygida (Diptera, Sciaridae)
(SPRINGER, 2008)
Gene amplification occurs in Bradysia hygida salivary glands, at the end of the fourth larval instar. The hormone 20-hydroxyecdysone (20E) triggers this process, which results in DNA puff formation. Amplified genes are ...
Functional and bioinformatics analyses reveal conservation of Cis-regulatory elements between sciaridae and Drosophilidae
(WILEY-LISS, 2008)
The sciarid DNA puff C4 BhC4-1 gene is amplified and transcribed in salivary glands at the end of the larval stage. In transgenic Drosophila, the BhC4-1 promoter drives transcription in prepupal salivary glands and in the ...
