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

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,

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 ...

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

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 ...

Deregulation of Chromosome Segregation and Cancer [PDF]
Annual Review of Cancer Biology, 2020 The mitotic spindle assembly checkpoint (SAC) is an intricate cell signaling system that ensures the high fidelity and timely segregation of chromosomes during cell division. Mistakes in this process can lead to the loss, gain, or rearrangement of the genetic material. Gross chromosomal aberrations are usually lethal but can cause birth and development

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.

Structure of the cohesin loader Scc2
Nature 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 ...
