    Allozyme polymorphism and linkage disequilibrium ofAdh and α-Gpdh loci in wine cellar and field populations ofDrosophila melanogaster (1986)
    Springer
    Cellular and molecular life sciences 42 (1986), S. 1048-1050

    Notes: Summary Over three years, theAdh and α-Gpdh loci have been studied in two cellar populations ofDrosophila melanogaster and in two field populations which were each near to one of the cellars. Analyses of gene frequencies indicate that the divergence among subpopulations is greater in theAdh locus than in the α-Gpdh locus. Selection for or againstAdh S allele acting on theIn(2L)t inversion influences of the α-Gpdh alleles. This phenomenon may contribute to explain the maintenance of theAdh and α-Gpdh polymorphism and of theIn(2L)t inversion.

    In vitro attempts to overcome the cross-incompatibility between Vaccinium corymbosum L. and V. elliottii Chapm. (1985)
    Springer
    Theoretical and applied genetics 69 (1985), S. 591-596 
    Details
    ISSN: 1432-2242
    Keywords: Interspecific hybridization ; Embryo rescue ; Ovule culture ; Ovary culture

    Topics: Biology
    Notes: Summary Seed was readily obtained from V. corymbosum zygotes using embryo rescue techniques, even when embryos were cultured at proembryonic stages. Best in vitro seed development was obtained when ovules were cultured attached to placental tissues. Successful fruit and seed development in culture occurred only when the fruit was cut longitudinally or when the basal portion of the fruit was removed previous to plating. Addition of various vitamins, amino acids, and growth regulators to the nutrient medium did not increase seed production. Attempts to rescue hybrid embryos from V. croymbosum (tetraploid) x V. elliottii (diploid) crosses by in ovulo and in ovary culture gave a few presumably hybrid seed, but at a rate no greater than when normal crossing procedures are used.
