Analysis of phenotypes altered by temperature stress and hipermutability in Drosophila willistoni
(2008) [Journal article]Drosophila willistoni (Sturtevant, 1916) é uma espécie do grupo willistoni de Drosophila que apresenta ampla distribuição geográfica desde o sul dos Estados Unidos (Flórida) e México até o norte da Argentina. Esta espécie ... -
Assemblages of drosophilids (Diptera, Drosophilidae) in mangrove forests : community ecology and species diversity
(2010) [Journal article]A fauna brasileira de drosofilídeos tem sido estudada em vários ecossistemas, mas os manguezais têm sido negligenciados a esse respeito no Brasil e em todo o mundo. O presente estudo traz uma caracterização das assembléias ... -
Chromosomal inversion polymorphism in Drosophila mediopunctata : seasonal, altitudinal, and latitudinal variation
(2004) [Journal article]The most polymorphic chromosome for inversions in Drosophila mediopunctata is the chromosome II, where 17 inversions have been found, eight of which occurring in the distal region and nine in the proximal region. We present ... -
Chromosomal polymorphism in Drosophila willistoni populations from Uruguay
(2003) [Journal article]Chromosomal polymorphism in natural populations of Drosophila willistoni from Uruguay and southern Brazil was investigated in order to understand the genetic characteristics and evolutionary potential of these almost ... -
Detection of P element transcripts in embryos of Drosophila melanogaster and D. willistoni
(2009) [Journal article]The P element is one of the most thoroughly studied transposable elements (TE). Its mobilization causes the hybrid dysgenesis that was first described in Drosophila melanogaster. While studies of the P element have mainly ... -
Distribution and conservation of the transposable element gypsy in Drosophilid species
(2007) [Journal article]In an attempt to understand the dynamics of transposable elements (T’S) in the genome of host species, we investigated the distribution, representativeness and conservation of DNA sequences homologous to the Drosophila ... -
Drosophila relics hobo and hobo-MITEs transposons as raw material for new regulatory networks
(2018) [Journal article]Hypermutable strains of Drosophila simulans have been studied for 20 years. Several mutants were isolated and characterized, some of which had phenotypes associated with alteration in development; for example, showing ... -
Drosophilidae (Diptera) associated to fungi : differential use of resources in anthropic and Atlantic Rain Forest areas
(2009) [Journal article]Foi realizado um estudo das espécies de Drosophilidae associadas aos corpos de frutificação de fungos em ambientes florestais e antrópicos no Bioma Mata Atlântica, no sul e sudeste do Brasil. Foram realizadas coletas de ... -
Drosophilids (Diptera) from an Atlantic Forest area in Santa Catarina, southern Brazil
(2008) [Journal article]O presente estudo tem como objetivo conhecer a composição da fauna de drosofilídeos em áreas de floresta no sul do Brasil. Além disso, a estimativa da riqueza de espécies desta fauna é brevemente discutida. As amostras ... -
Evolution of DNMT2 in drosophilids: evidence for positive and purifying selection and insights into new protein (pathways) interactions
(2018) [Journal article]The DNA methyltransferase 2 (DNMT2) protein is the most conserved member of the DNA methyltransferase family. Nevertheless, its substrate specificity is still controversial and elusive. The genomic role and determinants ... -
Horizontal transfer and the widespread presence of Galileo transposons in Drosophilidae (Insecta: Diptera)
(2023) [Journal article]Galileo is a transposon notoriously involved with inversions in Drosophila buzzatii by ectopic recombination. Although widespread in Drosophila, little is known about this transposon in other lineages of Drosophilidae. ... -
Interpopulation variation of transposable elements of the hAT superfamily in Drosophila willistoni (Diptera: Drosophilidae): in-situ approach
(2022) [Journal article]Transposable elements are abundant and dynamic part of the genome, influencing organisms in different ways through their presence or mobilization, or by acting directly on pre- and post-transcriptional regulatory regions. ... -
Isoenzymatic polymorphisms in urban populations of Drosophila willistoni
(2001) [Journal article]Natural populations of Drosophila willistoni collected both in urban sites and in the wild, as control, were analysed with respect to their isoenzyme polymorphisms in six loci of enzyme systems, through horizontal ... -
Mar, a MITE family of hAT transposons in Drosophila
(2012) [Journal article]Background: Miniature inverted-repeat transposable elements (MITEs) are short, nonautonomous DNA elements flanked by subterminal or terminal inverted repeats (TIRs) with no coding capacity. MITEs were originally recognized ... -
Mitotic and meiotic chromosomes of a southern brazilian population of Boophilus microplus (Acari, Ixodidae)
(2002) [Journal article]Using conventional staining with acetic orcein and C-banding techniques it was investigated constitutive heterochromatin chromosomal polymorphisms and the mitotic and the meiotic behavior of male and female chromosomes of ... -
New histochemical and morphological findings in the female genital tract of Boophilus microplus (Acari, Ixodidae) : an attempt toward the elucidation of fertilization in ticks
(2005) [Journal article]Até o momento, não só o lugar da fertilização em carrapatos é desconhecido, mas também não é claro como este mistério possa ser esclarecido. Sinais de fertilização podem ser observados ao longo do trato genital feminino e ... -
Over-activation of the Drosophila melanogaster hsp83 gene by selenium intoxication
(2008) [Journal article] -
Phylomitogenomics of two Neotropical species of long-legged crickets Endecous Saussure, 1878 (Orthoptera: Phalangopsidae)
(2023) [Journal article]Mitochondrial genomes have provided significant insights into the evolution of several insects. A typical mitogenome contains 37 genes, and variations in gene order can indicate evolutionary relationships between species. ... -
Rhinoleucophenga joaquina sp. nov. (Diptera: Drosophilidae) from the Neotropical Region
(2009) [Journal article]O gênero Rhinoleucophenga Hendel compreende 18 espécies nominais e possui distribuição Neotropical e Neártica. Uma nova espécie foi encontrada em coleta realizada em Florianópolis, SC, e é descrita como Rhinoleucophenga ... -
Spatiotemporal transcription of the P element and the 412 retrotransposon during embryogenesis of Drosophila melanogaster and D. willistoni
(2011) [Journal article]Transposable elements (TEs) are mobile nucleotide sequences which, through changing position in host genomes, partake in important evolutionary processes. The expression patterns of two TEs, P element transposon and 412 ...
