The Africanization process of Apis mellifera has raised several questions about the genetic makeup of resulting populations. This study aimed to identify the number, frequency and distribution of different mitochondrial ...

The Tribe Euglossini consists of relatively large bees, with metallic skin and bright color. Their extremely long tong enables them to use nectar resources that are inaccessible to other bees. Equipped with high capacity ...

Fish of the Schizodon genus have important representation in the largest South American basins. Historically they underwent through several taxonomic revisions, due to their high phenotypic plasticity and the ontogenetic ...

Parasitosis in fishes is a relevant problem in aquaculture. Besides, the organophosphate trichlorfon (2,2,2-trichloro-1-hydroxyethyl phosphonate) is amongst the most used medicine in farming of fishes. Due to trichlorfon ...

Parasitism by gastrointestinal nematodes, mainly by Haemonchus contortus, is the major obstacle to sheep production. Anthelmintic treatment is the main method used by farmers to control worms. However, parasites acquire ...

SCF complexes are composed by Skp1, Cullin1, Rbx1 and an F-box protein (FBP), which are responsible to give specificity to the complexes, as they interact with substrates, allowing ligation of an ubiquitin molecule to the ...

The genus Anastrepha which is endemic to the Neotropical region has big economic importance to cause great losses in fruit production. We studied three species of the cryptic group fraterculus: Anastrepha fraterculus, A. ...

Sugarcane rust (Puccinia melanocephala) is a major disease distributed throught the world, causing yield losses of 50% in conducive environments. Resistance is an essential trait to control rust in commercial cultivars ...

Orchid bees (Apidae, Euglossini) are important Neotropical pollinators. Two main features characterize these species: the tongue, which reaches at least half the body length, enabling the search for food resources in ...

Metagenomics studies allow the direct analysis of a genetic material in an environmental sample and when linked to bioinformatics it gives a powerful tool to explore the role of new genes and proteins not studied before. ...
