Three-dimensional organization of Drosophila melanogaster interphase nuclei. II. Chromosome spatial organization and gene regulation

In the preceding article we compared the general organization of polytene chromosomes in four different Drosophila melanogaster cell types. Here we describe experiments aimed at testing for a potential role of three-dimensional chromosome folding and positioning in modulating gene expression and examining specific chromosome interactions with different nuclear structures. By charting the config...

Three-Dimensional Organization of Drosophila melanogaster Interphase Nuclei. I. Tissue-specific Aspects of Polytene Nuclear Architecture

Interphase chromosome organization in four different Drosophila melanogaster tissues, covering three to four levels of polyteny, has been analyzed. The results are based primarily on three-dimensional reconstructions from unfixed tissues using a computerbased data collection and modeling system. A characteristic organization of chromosomes in each cell type is observed, independent of polyteny,...
