Chromosome segregation in plant meiosis [PDF]
Frontiers in Plant Science, 2014 Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

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 ...

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,

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 ...

Bacterial chromosome segregation [PDF]
Microbiology, 2001 Recent years have witnessed a resurgence of interest in how the bacterial chromosome is organized and how newly replicated chromosomes are faithfully segregated into daughter cells on cell division. In the past, the problem with studying bacterial chromosomes was their lack of any obvious morphology, combined with the lack of ability to readily ...

Prokaryotic ParA–ParB–parS system links bacterial chromosome segregation with the cell cycle [PDF]
, 2012 While the essential role of episomal par loci in plasmid DNA partitioning has long been appreciated, the function of chromosomally encoded par loci is less clear. The chromosomal parA–parB genes are conserved throughout the bacterial kingdom and encode

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.

Stochastic modelling of chromosomal segregation : errors can introduce correction [PDF]
, 2014 Cell division is a complex process requiring the cell to have many internal checks so that division may proceed and be completed correctly. Failure to divide correctly can have serious consequences, including progression to cancer.

CHROMOSOME SEGREGATION MECHANISMS [PDF]
Genetics, 1974 ABSTRACT Most aspects of chromosome distribution to the daughter cells in meiosis and mitosis are now understood, at the cellular level. The most striking evidence that the proposed explanation is valid is that it correctly predicts the outcome of experiments on living cells in which the experimenter (1) can determine the distribution of
