The gene transformer-2 of Anastrepha fruit flies (Diptera, Tephritidae) and its evolution in insects
Background In the tephritids Ceratitis, Bactrocera and Anastrepha, the gene transformer provides the memory device for sex determination via its auto-regulation; only in females is functional TraExpand

The Gene Transformer of Anastrepha Fruit Flies (Diptera, Tephritidae) and Its Evolution in Insects
In the tephritids Ceratitis capitata and Bactrocera oleae, the gene transformer acts as the memory device for sex determination, via an auto-regulatory function; and functional Tra protein isExpand

Isolation and characterization of the Bactrocera oleae genes orthologous to the sex determining Sex-lethal and doublesex genes of Drosophila melanogaster.
Here we report the isolation and characterization of the olive fruit fly Bactrocera oleae genes orthologous to the Drosophila melanogaster sex-determining genes Sex-lethal (Sxl) and doublesex (dsx).Expand

The gene transformer-2 of Sciara (Diptera, Nematocera) and its effect on Drosophila sexual development
BackgroundThe gene transformer-2, which is involved in sex determination, has been studied in Drosophila, Musca, Ceratitis, Anastrepha and Lucilia. All these members of Diptera belong to the suborderExpand

The gene doublesex of Anastrepha fruit flies (Diptera, Tephritidae) and its evolution in insects
The doublesex (dsx) gene of several Anastrepha species was isolated and characterised. Its molecular organisation was found to be the same in all the species examined. This gene is composed of fourExpand

Two new chromodomain-containing proteins that associate with heterochromatin in Sciara coprophila chromosomes
We report here the molecular and cytological characterization of two proteins, ScoHET1 and ScoHET2 (for Sciara coprophila heterochromatin), which associate to constitutive heterochromatin in theExpand

Differential acetylation of histones H3 and H4 in paternal and maternal germline chromosomes during development of sciarid flies
A classic example of chromosome elimination and genomic imprinting is found in sciarid flies (Diptera. Sciaridae), where whole chromosomes of exclusively paternal origin are discarded from the genomeExpand

The Drosophila fl(2)d gene, required for female-specific splicing of Sxl and tra pre-mRNAs, encodes a novel nuclear protein with a HQ-rich domain.
The Drosophila gene female-lethal(2)d [fl(2)d] interacts genetically with the master regulatory gene for sex determination, Sex-lethal. Both genes are required for the activation of female-specificExpand
