The Arrangement of Genes in Drosophila Virilis.
cism misses the mark. It need only be stated that Castle was wrong in supposing that the cross-overs between yellow and white should be subtracted from the total before the white bifid cross-over value is calculated. If, as Castle states, he cannot conceive of a mechanism "which would tie two genes together in such a way that they will subsequently separate from each other oftener than they wil...
متن کاملStructural and functional comparisons of the Drosophila virilis and Drosophila melanogaster rough genes.
We have isolated the homeobox gene rough (ro) from Drosophila virilis. Comparison of the predicted amino acid sequences of the D. melanogaster and D. virilis rough proteins reveals that domains of high conservation, including the homeodomain, are interspersed with highly diverged regions. Stretches of significant sequence conservation are also observed in the 5' promoter region and in the intro...
متن کاملAn Analysis of the Chromosomes of the Two Sub-Species Drosophila Virilis Virilis and Drosophila Virilis Americana.
NCREASING attention is being focused on the use of Drosophila as a I convenient organism for investigating such fundamental problems as the formation of new species and interspecific sterility. Studies of the hybrid from the cross D. melarzogasterXD. simulans by PATAU (I935), and by HORTON (1939), and D. pseudoobscuraXD. miranda by DOBZHANSKY and TAN (1936), as well as studies of the hybrids fr...
متن کاملThe interaction of bride of sevenless with sevenless is conserved between Drosophila virilis and Drosophila melanogaster.
An inductive interaction between the sevenless (sev) transmembrane tyrosine kinase receptor and the bride of sevenless (boss) transmembrane ligand is required for the development of the R7 photoreceptor neuron in the compound eye of Drosophila melanogaster. The boss protein is proposed to contain a large N-terminal extracellular domain, seven transmembrane segments, and a C-terminal cytoplasmic...
متن کاملComparison of the sevenless genes of Drosophila virilis and Drosophila melanogaster.
The sevenless gene of Drosophila melanogaster encodes a transmembrane tyrosine kinase receptor required for normal eye development. We report here the isolation and DNA sequence analysis of the sevenless gene from Drosophila virilis. The predicted amino acid sequences of the sevenless proteins from these two species, which diverged approximately 60 million years ago, are compared.
