A 14 bp promoter element directs the testis specificity of the Drosophila beta 2 tubulin gene.
To analyze the regulation of gene expression during male germ cell development, we investigated the testis‐specific expression of the Drosophila beta 2 tubulin gene. Germ line transformation… Expand
Characterization and developmental expression of beta tubulin genes in Drosophila melanogaster.
Genomic clones containing beta tubulin sequences were isolated from a lambda library of Drosophila melanogaster. In situ hybridization localized three genes to 56D and 60B on chromosome 2 as well as… Expand
Testis-specific β2 tubulins are identical in Drosophila melanogaster and D. hydei but differ from the ubiquitous β1 tubulin
In Drosophila as in many organisms β tubulins are encoded by a gene family. We have determined the complete nucleotide sequences coding for the β1 and β2 tubulins of Drosophila melanogaster and the… Expand
Characterization of cloned ribosomal DNA from Drosophila hydei.
The structure of ribosomal genes from the fly Drosophila hydei has been analyzed. EcoRI fragments, cloned in a plasmid vector, were mapped by restriction enzyme analysis. The lengths of the regions… Expand
Underreplication of satellite DNAs in polyploid ovarian tissue of Drosophila virilis
The satellite DNAs of Drosophila virilis have been examined in diploid and polyploid tissues by isopycnic ultracentrifugation and thermal denaturation experiments. Previous work has established that… Expand
A DNA sequence of Drosophila melanogaster with a differential telomeric distribution
A DNA sequence (8–19T) of 2.3 kilobase pairs (kb) of Drosophila melanogaster was localized by in situ hybridization to the extreme ends of polytene chromosomes and to the chromocenter. The relative… Expand
Testis-specific beta 2 tubulins are identical in Drosophila melanogaster and D. hydei but differ from the ubiquitous beta 1 tubulin.
In Drosophila as in many organisms beta tubulins are encoded by a gene family. We have determined the complete nucleotide sequences coding for the beta 1 and beta 2 tubulins of Drosophila… Expand
Further sequence requirements for male germ cell-specific expression under the control of the 14 bp promoter element (β2UE1) of the Drosophila β2 tubulin gene
Abstract We have investigated a 14 bp promoter element (beta 2UE1) that is required for testis-specific expression of the Drosophila beta 2 tubulin gene. To further elucidate the role of the 14 bp… Expand
Cloning and identification of the gene coding for the 140‐kd subunit of Drosophila RNA polymerase II
Genomic clones of Drosophila melanogaster were isolated from a λ library by cross‐hybridization with the yeast gene coding for the 150‐kd subunit of RNA polymerase II. Clones containing a region of… Expand
Ribosomal RNA genes with an intervening sequence are clustered within the X chromosomal ribosomal DNA of Drosophila hydei.
Abstract The X chromosomal nucleolus organizer of Drosophila hydei contains about 500 ribosomal RNA genes. The 28 S rRNA coding region of about 50% of these genes is interrupted by an intervening… Expand
