Journal ArticleDOI
Mutations in twinstar, a Drosophila gene encoding a cofilin/ADF homologue, result in defects in centrosome migration and cytokinesis.
Kristin C. Gunsalus,Silvia Bonaccorsi,Erika V. Williams,Fiammetta Vernì,Maurizio Gatti,Michael L. Goldberg +5 more
TL;DR: The phenotypic and molecular characterization of twinstar (tsr), an essential gene in Drosophila melanogaster, is described and possible roles of the actin-based cytoskeleton in centrosome movement and in cytokinesis are discussed.
Journal ArticleDOI
Transposable elements are stable structural components of Drosophila melanogaster heterochromatin.
Sergio Pimpinelli,Maria Berloco,Laura Fanti,Patrizio Dimitri,Silvia Bonaccorsi,Enzo Marchetti,R. Caizzi,C Caggese,Maurizio Gatti +8 more
TL;DR: The distribution of 11 different transposable elements on Drosophila melanogaster mitotic chromosomes is determined by using high-resolution fluorescent in situ hybridization (FISH) coupled with charge-coupled device camera analysis to change the current views on the role of transposables elements in host genome evolution.
Journal ArticleDOI
Chromatin and microtubule organization during premeiotic, meiotic and early postmeiotic stages of Drosophila melanogaster spermatogenesis.
TL;DR: By means of bromo-deoxyuridine incorporation experiments, it is demonstrated that premeiotic DNA synthesis occurs very early during spermatocyte growth and meiotic divisions.
Journal ArticleDOI
Cooperative interactions between the central spindle and the contractile ring during Drosophila cytokinesis
Maria Grazia Giansanti,Silvia Bonaccorsi,Byron C. Williams,Erika V. Williams,Carlo Santolamazza,Michael L. Goldberg,Maurizio Gatti +6 more
TL;DR: Male meiosis in mutants of the chickadee (chic) locus, a Drosophila melanogaster gene that encodes profilin, a low molecular weight actin-binding protein that modulates F-actin polymerization indicates that proper actin assembly is necessary for centrosome separation and migration.
Journal ArticleDOI
Spindle self-organization and cytokinesis during male meiosis in asterless mutants of Drosophila melanogaster
TL;DR: These findings challenge the classical view on central spindle assembly, arguing for a self-organization of this structure from either preexisting or newly formed microtubules, and strongly suggest that the asters are not required for signaling cytokinesis.
