The Drosophila Calcipressin Sarah Is Required for Several Aspects of Egg Activation
Activation of mature oocytes initiates development by releasing the prior arrest of female meiosis, degrading certain maternal mRNAs while initiating the translation of others, and modifying egg… Expand
The Drosophila kinesin-like protein KLP3A is required for proper behavior of male and female pronuclei at fertilization.
Drosophila melanogaster females homozygous for mutations in the gene encoding the kinesin-like protein KLP3A are sterile (Williams et al., 1995). We have investigated the basis of this sterility. The… Expand
The Ketel(D) dominant-negative mutations identify maternal function of the Drosophila importin-beta gene required for cleavage nuclei formation.
The Ketel(D) dominant female-sterile mutations and their ketel(r) revertant alleles identify the Ketel gene, which encodes the importin-beta (karyopherin-beta) homologue of Drosophila melanogaster.… Expand

Abstract The distributions of 3rd chromosome recessive lethals and cross-overs were studied in daily post-sterile broods of Drosophila melanogaster males treated as adults with 3000 R X-rays and… Expand
Meiotic segregation of chromosomes in Drosophila melanogaster oocytes
A new technique was developed for a light microscopic analysis of meiosis in Drosophila oocytes. — When the nuclear envelope breaks down the bivalents, till then compressed into a karyosome, separate… Expand
Horka, a dominant mutation of Drosophila, induces nondisjunction and, through paternal effect, chromosome loss and genetic mosaics.
Fs(3)Horka (Horka) was described as a dominant female-sterile mutation of Drosophila melanogaster. Genetic and cytological data show that Horka induces mostly equational nondisjunction during… Expand
Cytological evidence for a chromocenter in Drosophila melanogaster oocytes.
Recombination and disjunction in female germ cells of Drosophila depend on the germline activity of the gene sex-lethal.
Gametogenesis in males and females differs in many ways. An important difference in Drosophila is that recombination between homologous chromosomes occurs only in female meiosis. Here, we report that… Expand
Terminal chromosome attachments.
Descriptions are presented of four cases of attachment of chromosome material at the ends of normal chromosomes in Drosophila. Since no material appears to be missing from the polytene chromosomes… Expand
Dominant-negative mutant dynein allows spontaneous centrosome assembly, uncouples chromosome and centrosome cycles
Cleavage cycles commence and chromosome and centrosome cycles proceed in harmony following fertilization of Drosophila eggs and completion of the meiotic divisions. The sperm-introduced centrioles… Expand
