Peroxisomes in wild-type and rosy mutant Drosophila melanogaster.
This study shows that peroxisomes are abundant in the Malpighian tubule and gut of wild-type Oregon R Drosophila melanogaster and that the peroxisomal population of the rosy-506 eye-color mutant differs from that of the wild type. Catalase activity in wild-type flies is demonstrable in bodies of appearance and centrifugal behavior comparable to the peroxisomes of vertebrate tissues. Xanthine ox...
متن کاملMutations affecting expression of the rosy locus in Drosophila melanogaster.
The rosy locus in Drosophila melanogaster codes for the enzyme xanthine dehydrogenase (XDH). Previous studies defined a "control element" near the 5' end of the gene, where variant sites affected the amount of rosy mRNA and protein produced. We have determined the DNA sequence of this region from both genomic and cDNA clones, and from the ry+10 underproducer strain. This variant strain had many...
متن کاملSpontaneous unequal exchange in the rosy region of Drosophila melanogaster.
A selective system for recovery of exchanges between trans mutations at adjacent loci, l(3)S12 and rosy, is described. In addition to the expected crossover and conversion classes, two exceptional types of offspring were recovered. Triploid offspring arose as 0.01% of all zygotes; the diploid chromosome set was apparently of maternal origin. Nine tandem duplications derived from unequal exchang...
متن کاملMolecular mapping of the rosy locus in Drosophila melanogaster.
The DNA from the chromosomal region of the Drosophila rosy locus has been examined in 83 rosy mutant strains. Several spontaneous and radiation-induced alleles were associated with insertions and deletions, respectively. The lesions are clustered in a 4-kb region. Some of the alleles identified on the DNA map have been located on the genetic map by fine-structure recombination experiments. The ...
متن کاملThe Rosy Cistron in Drosophila Melanogaster: Genetic Fine Structure Analysis.
O N E of the major directions of research bearing on the organization of the genetic material was initiated with the first reports of exceptional segregants among the progeny of females of Drosophila melanogaster heterozygous for two different mutant alleles of a given gene, and the association of these exceptions with crossing over (OLIVER 1940; LEWIS 1941). These reports led to extensive reex...
