Chromosome segregation in plant meiosis [PDF]

open access: yesFrontiers 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

Coupling chromosome organization to genome segregation in Archaea [PDF]

open access: yesNature Communications
Chromosome segregation is a fundamental process in all life forms and requires coordination with genome organization, replication and cell division. The mechanism that mediates chromosome segregation in archaea remains enigmatic.

Prokaryotic ParA–ParB–parS system links bacterial chromosome segregation with the cell cycle [PDF]

open access: yes, 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

Chromosome segregation impacts on cell growth and division site selection in Corynebacterium glutamicum. [PDF]

open access: yes, 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 ...

The MatP/matS Site-Specific System Organizes the Terminus Region of the E. coli Chromosome into a Macrodomain [PDF]

open access: yes, 2008
The organization of the Escherichia coli chromosome into insulated macrodomains influences the segregation of sister chromatids and the mobility of chromosomal DNA.

Subunit interactions and arrangements in the fission yeast Mis16–Mis18–Mis19 complex

open access: yesLife Science Alliance, 2019
A structural study of the fission yeast Mis19 protein, required for centromere establishment, is presented together with data describing its interactions with functional partners Mis16 and Mis18. Centromeric chromatin in fission yeast is distinguished by

The role of CSE1L expression in cervical lymph node metastasis of larynx tumors

open access: yesBrazilian Journal of Otorhinolaryngology, 2021
Introduction: According to international reports, 30–40% of all head and neck cancers are larynx cancers, comprising 1–2.5% of all cancer types. Cervical nodal involvement has been reported to be 40% and 65% in T3 and T4 cases, respectively.

Stochastic modelling of chromosomal segregation : errors can introduce correction [PDF]

open access: yes, 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.

Exotic mitotic mechanisms [PDF]

open access: yes, 2012
The emergence of eukaryotes around two billion years ago provided new challenges for the chromosome segregation machineries: the physical separation of multiple large and linear chromosomes from the microtubule-organizing centres by the nuclear envelope.

Structure of the cohesin loader Scc2

open access: yesNature Communications, 2017
The cohesin complex maintains genome integrity by ensuring correct sister-chromatid segregation during mitosis and meiosis. Here, Chaoet al. present a pseudo-atomic model of the full-length Scc2–Scc4 cohesin loader complex and reveal key Scc2 surfaces ...
