Mechanisms for Chromosome Segregation in Bacteria [PDF]
Frontiers in Microbiology, 2021 The process of DNA segregation, the redistribution of newly replicated genomic material to daughter cells, is a crucial step in the life cycle of all living systems. Here, we review DNA segregation in bacteria which evolved a variety of mechanisms for partitioning newly replicated DNA.

Cohesin and chromosome segregation [PDF]
Current Biology, 2018 Cohesin is a ring-shaped protein complex that organises the genome, enabling its condensation, expression, repair and transmission. Cohesin is best known for its role in chromosome segregation, where it provides the cohesion that is established between the two newly duplicated sister chromatids during S phase.

Chromosome segregation in Eubacteria [PDF]
Current Opinion in Microbiology, 2003 It is now clear that bacterial chromosomes rapidly separate in a manner independent of cell elongation, suggesting the existence of a mitotic apparatus in bacteria. Recent studies of bacterial cells reveal filamentous structures similar to the eukaryotic cytoskeleton, proteins that mediate polar chromosome anchoring during Bacillus subtilis sporulation,

Developmental Cell, 2002 During mitosis, in most eukaryotes, cohesin is removed from chromosomes in two steps. A paper in the March issue of Molecular Cell identifies Polo-like kinase as a key regulator for the first step that releases much of cohesin during prophase.

Chromosome segregation impacts on cell growth and division site selection in Corynebacterium glutamicum. [PDF]
, 2013 Spatial and temporal regulation of bacterial cell division is imperative for the production of viable offspring. In many rod-shaped bacteria, regulatory systems such as the Min system and nucleoid occlusion ensure the high fidelity of midcell divisome ...

Nature Communications, 2020 Oocyte meiosis must achieve spindle bipolarization without predefined spatial cues. Yoshida et al. demonstrate that spindle bipolarization during meiosis I in mouse oocytes requires kinetochores to prevent chromosome segregation errors, a phenomenon that

SMC is recruited to oriC by ParB and promotes chromosome segregation in Streptococcus pneumoniae [PDF]
, 2011 Segregation of replicated chromosomes is an essential process in all organisms. How bacteria, such as the oval-shaped human pathogen Streptococcus pneumoniae, efficiently segregate their chromosomes is poorly understood.

Current Opinion in Microbiology, 2001 The ability to visualise specific genes and proteins within bacterial cells is revolutionising knowledge of chromosome segregation. The essential elements appear to be the driving force behind DNA replication, which occurs at fixed cellular positions, the condensation of newly replicated DNA by a chromosome condensation machine located at the cell 1/4 ...

Cell-Cycle Regulation of Dynamic Chromosome Association of the Condensin Complex
Cell Reports, 2018 Summary: Eukaryotic cells inherit their genomes in the form of chromosomes, which are formed from the compaction of interphase chromatin by the condensin complex. Condensin is a member of the structural maintenance of chromosomes (SMC) family of ATPases,
