    Temperature-dependent responses to a developmental gradient in theDrosophila wing (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1346-1347 
    Details
    ISSN: 1420-9071
    Keywords: Positional information ; temperature effects ; gradients ; campaniform sensillae ; wing veins ; Drosophila melanogaster
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The mutant hairy (h) increases the number of sensillae on theDrosophila wing. This allows us to quantify a gradient that determines the type of sense organ that forms along the third long vein. Temperature significantly shifts the positional responses to this underlying gradient.

    Acetaldehyde oxidation inDrosophila null-mutants for alcohol dehydrogenase (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 946-948 
    Details
    ISSN: 1420-9071
    Keywords: Acetaldehyde oxydation ; alcohol dehydrogenase ; aldehyde dehydrogenase ; Drosophila melanogaster ; Drosophila simulans ; ethanol catabolism ; null-mutants for alcohol dehydrogenase
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Aldehyde dehydrogenase (ALDH) activity is demonstrated in four strains ofD. melanogaster lacking active alcohol dehydrogenase (ADH-null mutants). In the four strains, ALDH activities are similar to those found in a wild strain. It is concluded that ADH-null flies are able to detoxify acetaldehyde. This finding is discussed in relation with the dual function of ADH proposed recently.

    Effect of intercalating mutagens on crossing-over inDrosophila melanogaster females (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1078-1079 
    Details
    ISSN: 1420-9071
    Keywords: Drosophila melanogaster ; intercalating mutagens ; crossing-over ; clastogenic activity ; recombination induction
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary In order to evaluate the effect of several intercalating compounds on crossing-over inDrosophila melanogaster females, acridine orange, acriflavine, chloroquine, ethidium bromide and quinacrine were fed separately to larvae ofy ct f/+++ genotype. Our results show that acridine orange, acriflavine and ethidium bromide increase significantly the recombination frequency at thect-f region and support the view that, for intercalating agents, there is a relationship between clastogenic activity and female recombination induction.

    Localization of cells capable of transdetermination in a specific region of the male foreleg disk ofDrosophila (1977)
    Springer
    Development genes and evolution 182 (1977), S. 69-74 
    Details
    ISSN: 1432-041X
    Keywords: Drosophila melanogaster ; Male foreleg disk ; Capacity of transdetermination
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary In the male foreleg disk ofDrosophila melanogaster the cells capable of transdetermination are clustered in a specific region within the upper half of the disk. Cells outside this region cannot transdetermine under any of the experimental conditions thus far applied. Transdetermination occurs when cells capable of transdetermination are stimulated to a certain extent of additional proliferation. This can be achieved either by exposing these cells at a wound surface of an intact fragment, or by dissociation.

    Further studies onengrailed mutants inDrosophila melanogaster (1985)
    Springer
    Development genes and evolution 194 (1985), S. 236-246 
    Details
    ISSN: 1432-041X
    Keywords: Drosophila melanogaster ; engrailed ; Selector gene ; Genetic complementation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary In 1975, Morata and Lawrence proposed that theengrailed (en) locus was a selector gene that controlled the different pathways of development followed by anterior and posterior compartments. This hypothesis assumed that the phenotype ofen 1 flies results from partial inactivity of theen + product. However, the mutant phenotype ofen 1/DF(2R)en − is weaker thanen 1/en 1. This implies that the partial P→A transformation ofen 1 does not result primarily from reduction inen + activity. Heterozygotes betweenl(2) en alleles andDf(2R)en − deletions express a similar phenotype of fused embryonic segments to that described by Nüsslein-Volhard and Wieschaus, and also by Kornberg, forl(2) en homozygoes. By this criterion, the lethal phenotype results from partial or complete lack ofen _ activity. Despite this, the1(2) en alleles give only a weak P→A transformation, whether recovered as embryonic lethals or by failure to complementen 1. They appear to define only one locus and, with the exception ofen 1, the available genetic date suggest that the complementation pattern at this locus is simple. Thus, it is unlikely thatengrailed is the sole determinant of the A/P compartment separation. It might be one of a number of loci that affect the alternative pathways followed by anterior and posterior compartments.

    Sensory projections from dorsal and ventral appendages inDrosophila grafted to the same site are different (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1607-1609 
    Details
    ISSN: 1420-9071
    Keywords: Neuronal specificity ; sensory projections ; serial homology ; ectopic transplantation ; Drosophila melanogaster
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Owing to a new transplantation technique, we have been able to study the sensory projections of homologous and heterologous appendages grafted to the same abdominal site inD. melanogaster. Axons from homologous transplants exhibit similar terminal patterns, whereas those from heterologous transplants do not. It is suggested that ectopic sensory axons specifically recognized central areas and pathways occupied by axons from homologous appendages.

    Genetic load and effective size of natural populations ofDrosophila melanogaster in Korea (1985)
    Springer

    ISSN: 1420-9071
    Keywords: Drosophila melanogaster ; second chromosome ; drastics ; genetic load ; population size
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The effect of 750 second chromosomes ofDrosophila melanogaster on viability was studied. 19.3% of them proved letal or semilethal (=drastics) in homozygous condition. Compared to data obtained in previous years at the same sampling site, a significant frequency decrease of drastics during the past decade could be observed. The dynamic processes taking place in the Korean wild populations ofD. melanogaster are discussed.

    Mobile gene localization and viability inDrosophila melanogaster (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1474-1476

    ISSN: 1420-9071
    Keywords: Mobile elements ; inbreeding ; in situ hybridization ; Drosophila melanogaster
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The location of the mobile element mdg-1 was determined by in situ hybridization in salivary gland chromosomes ofDrosophila melanogaster. The locations of mdg-1 are nonrandom and some ‘hot spots’ exist. Moreover, the spectra of mdg-1 locations vary with the viability values of the families from which the larvae originated. This suggests that particular frequency spectra are associated with lethality resulting from inbreeding.
