Chromosome Organization: Original Condensins [PDF]
Current Biology, 2014 Two new studies reveal the main actors involved in the resolution and segregation of newly replicated origins in bacteria. These results have important implications for our understanding of the mechanisms involved in precisely coordinating chromosome organization, segregation and replication.

Cell Reports, 2016 Smc/ScpAB promotes chromosome segregation in prokaryotes, presumably by compacting and resolving nascent sister chromosomes. The underlying mechanisms, however, are poorly understood.

Organization of the Chromosome
Cold Spring Harbor Symposia on Quantitative Biology, 1956 The observational and experimental results presented here constitute another chapter in a continuing research program that is directed toward an understanding of patterns of organization of chromosomal materials. Evidence has been sought over the years at various levels of analysis, beginning with descriptive cytology, progressing into the areas of ...

Entropic organization of interphase chromosomes [PDF]
Journal of Cell Biology, 2009 Chromosomes are not distributed randomly in nuclei. Appropriate positioning can activate (or repress) genes by bringing them closer to active (or inactive) compartments like euchromatin (or heterochromatin), and this is usually assumed to be driven by specific local forces (e.g., involving H bonds between nucleosomes or between nucleosomes and the ...

eLife, 2015 Smc–ScpAB forms elongated, annular structures that promote chromosome segregation, presumably by compacting and resolving sister DNA molecules. The mechanistic basis for its action, however, is only poorly understood. Here, we have established a physical

Bacterial chromosome segregation by the ParABS system [PDF]
Open Biology, 2020 Proper chromosome segregation during cell division is essential in all domains of life. In the majority of bacterial species, faithful chromosome segregation is mediated by the tripartite ParABS system, consisting of an ATPase protein ParA, a CTPase and ...

The architecture of chicken chromosome territories changes during differentiation [PDF]
, 2004 BACKGROUND: Between cell divisions the chromatin fiber of each chromosome is restricted to a subvolume of the interphase cell nucleus called chromosome territory.

Nature Communications, 2020 Auxin-inducible degron systems can be leaky and require high doses of auxin. Here the authors establish AID2 which uses an OsTIR1 mutant and the ligand 5-Ph-IAA to overcome these problems and establish AID-mediated target depletion in mice.

The MatP/matS Site-Specific System Organizes the Terminus Region of the E. coli Chromosome into a Macrodomain [PDF]
, 2008 The organization of the Escherichia coli chromosome into insulated macrodomains influences the segregation of sister chromatids and the mobility of chromosomal DNA.

Three-dimensional chromosome organization in flowering plants.
Briefings in Functional Genomics, 2020 Research on plant three-dimensional (3D) genome architecture made rapid progress over the past 5 years. Numerous Hi-C interaction data sets were generated in a wide range of plant species, allowing for a comprehensive overview on 3D chromosome folding ...
