- Moore D, Miyazaki W, Tomkiel J, Orr Weaver T. Double or nothing: a Drosophila mutation affecting meiotic chromosome segregation in both females and males. Genetics. 1994;136:953-64 pubmed..Dub results in nondisjunction of all chromosomes in meiosis I of males, although the levels are lower than in females. When homozygous, Dub is a conditional lethal allele and exhibits phenotypes consistent with cell death. ..
- Krider H, Levine B. Studies on the mutation abnormal oocyte and its interaction with the ribosomal DNA of Drosophila melanogaster. Genetics. 1975;81:501-13 pubmedSandler (1970) suggested that mutation, abnormal oocyte (abo:2-38), may influence the function of the ribosomal RNA cistrons. We have examined the abo mutation and its interaction with the ribosomal DNA of Drosophila melanogaster...

Genetics. 1991;128:583-94 pubmedThe euchromatic maternal-effect mutation abnormal oocyte (abo), of Drosophila melanogaster interacts with regions of heterochromatin known as ABO, which reside on the X, Y and second chromosomes...

Genetics. 1985;111:487-94 pubmedThe authors have studied the interaction between the abnormal oocyte mutation and an inversion of the X chromosome, In( 1)sc(4), which has a proximal breakpoint in or near the heterochromatic region (ABO) that maternally interacts with ..
- Cohen S, Agmon N, Yacobi K, Mislovati M, Segal D. Evidence for rolling circle replication of tandem genes in Drosophila. Nucleic Acids Res. 2005;33:4519-26 pubmed..RCIs are detected throughout the life cycle of Drosophila and in cultured fly cells. These structures are found regardless of the expression of the replicated gene or of its chromosomal copy number. ..

Mol Gen Genet. 1991;230:433-41 pubmedThe abnormal oocyte phenotype is characterized by instability, as shown by the loss and reappearance of the abo maternal effect under specific genetic conditions...

Nup154, a new Drosophila gene essential for male and female gametogenesis is related to the nup155 vertebrate nucleoporin gene. J Cell Biol. 1998;142:1195-207 pubmed..Finally, the multiplicity of phenotypes observed in Nup154 mutant alleles suggests that this gene plays a crucial role in cell physiology. ..

Genetics. 1989;123:485-94 pubmedThe abnormal oocyte mutation (2;44) originates in the wild: it confers no visible phenotype on homozygous abo males or females, but homozygous abo females produce defective eggs and the probability of their developing into adults is much ..
