2. Alcohol dehydrogenase activities and ethanol tolerance in Anastrepha (Diptera, Tephritidae) fruit-fly species and their hybrids
The ADH (alcohol dehydrogenase) system is one of the earliest known models of molecular evolution, and is still the most studied in Drosophila. Herein, we studied this model in the genus Anastrepha (Diptera, Tephritidae). Due to the remarkable advantages it presents, it is possible to cross species with different Adh genotypes and with different phenotype tr

3. Wolbachia e incompatibilidade citoplasmática em Anastrepha sp. 1 aff. fraterculus e A. obliqua (Diptera: Tephritidae) / Wolbachia and cytoplasmic incompatibility into Anastrepha sp.1 aff. fraterculus and Anastrepha obliqua. (Diptera: Tephritidae)
The endosymbiont bacteria Wolbachia are vertically transmitted by the females to its progenies, although horizontal transmission between distinct taxa is also known. One of the most relevant effects caused by these bacteria in the reproductive behavior of its hosts is the cytoplasmic incompatibility (CI). Wolbachia was described in several groups of arthropo

4. Análise do ITS1 do DNA ribossômico em espécies do complexo Anastrepha fraterculus (Diptera: Tephritidae) / Analysis of ITS1 of ribosomal DNA in Species of the Anastrepha fraterculus complex (Diptera: Tephritidae).
Fruit flies of Tephritidae family are important pest for the worldwide fruitculture because many species use commercial variety of fruits as host for the development of thier larval stage. Anastrepha is endemic of the American Continent and comprises about 200 described species, 90 of which occurs in Brazil. Among these species the most important is the nomi

5. Screening the fruitfly immune system
The anti-microbial defense system of Drosophila shows functional similarities with the vertebrate innate immune system. Two recent gene-expression profiling studies of fruitflies challenged with infectious agents have identified key molecular players in the fruitfly's response to bacterial and fungal infection, as well as a large number of immune-regulated g

7. Membrane traffic between genomes
Proteins of the Rab and SNARE families target vesicles to their intracellular destinations. A comparison of these families from the budding yeast, fission yeast, nematode and fruitfly genomes has implications for the organization of membrane traffic in different organisms.

8. Overexpression of the Disease Resistance Gene Pto in Tomato Induces Gene Expression Changes Similar to Immune Responses in Human and Fruitfly1[w]
The Pto gene encodes a serine/threonine protein kinase that confers resistance in tomato (Lycopersicon esculentum) to Pseudomonas syringae pv tomato strains that express the type III effector protein AvrPto. Constitutive overexpression of Pto in tomato, in the absence of AvrPto, activates defense responses and confers resistance to several diverse bacte

9. Delayed male maturity is a cost of producing large sperm in Drosophila.
Among fruit-fly species of the genus Drosophila there is remarkable variation in sperm length, with some species producing gigantic sperm (e.g., > 10 times total male body length). These flies are also unusual in that males of some species exhibit a prolonged adult nonreproductive phase. We document sperm length, body size, and sex-specific ages of reproduct

10. Molecular identification of the insect adipokinetic hormone receptors
The insect adipokinetic hormones (AKHs) are a large family of peptide hormones that are involved in the mobilization of sugar and lipids from the insect fat body during energy-requiring activities such as flight and locomotion, but that also contribute to hemolymph sugar homeostasis. Here, we have identified the first insect AKH receptors, namely those from

11. Aberrant Splicing and Transcription Termination Caused by P Element Insertion into the Intron of a Drosophila Gene
Insertional mutagenesis screens using the P[lacZ, rosy(+)] (PZ) transposable element have provided thousands of mutant lines for analyzing genes of varied function in the fruitfly, Drosophila melanogaster. As has been observed with other P elements, many of the PZ-induced mutations result from insertion of the P element into the promoter or 5' untranslated r

12. The FlyBase database of the Drosophila Genome Projects and community literature. The FlyBase Consortium.
The FlyBase Drosophila genetics database and the public interfaces of the Berkeley Drosophila Genome Project (BDGP) and European Drosophila Genome Project (EDGP) are in the process of integrating. At present, the data of these projects are available from independent, but hyperlinked, WWW sites (FlyBase URL, http://flybase. bio.indiana.edu/; BDGP URL, http://
