Chiasmata promote monopolar attachment of sister chromatids and their co-segregation toward the proper pole during meiosis I. [PDF]
PLoS Genetics, 2011 The chiasma is a structure that forms between a pair of homologous chromosomes by crossover recombination and physically links the homologous chromosomes during meiosis. Chiasmata are essential for the attachment of the homologous chromosomes to opposite

The Drosophila histone variant H2A.V works in concert with HP1 to promote kinetochore-driven microtubule formation [PDF]
, 2015 Unlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles.

A theoretical model of anaphase
Mathematical BiosciencesThis paper develops a theory for anaphase in cells. After a brief description of microtubules, the mitotic spindle and the centrosome, a mathematical model for anaphase is introduced and developed in the context of the cell cytoplasm and liquid crystalline structures.

The Application of Carbon Dots in Crops for Sustainable Agriculture
ChemistryEurope, EarlyView.Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Dynamic SUMO remodeling drives a series of critical events during the meiotic divisions in Caenorhabditis elegans. [PDF]
PLoS Genetics, 2018 Chromosome congression and segregation in C. elegans oocytes depend on a complex of conserved proteins that forms a ring around the center of each bivalent during prometaphase; these complexes are then removed from chromosomes at anaphase onset and ...

Anaphase specific auto‐cleavage of separase [PDF]
FEBS Letters, 2002 Sister‐chromatid separation is triggered by a specific proteolytic cleavage of chromosomal cohesins catalyzed by the endopeptidase separase. Prior to anaphase, separase is inhibited independently by affinity binding to securin and by specific inhibitory phosphorylation.

Interaction Between Actin and Microtubules During Plant Development
Cytoskeleton, EarlyView.ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

The FEAR protein Slk19 restricts Cdc14 phosphatase to the nucleus until the end of anaphase, regulating its participation in mitotic exit in Saccharomyces cerevisiae. [PDF]
PLoS ONE, 2013 In Saccharomyces cerevisiae mitosis, the protein Slk19 plays an important role in the initial release of Cdc14 phosphatase from the nucleolus to the nucleus in early anaphase, an event that is critical for proper anaphase progression. A role for Slk19 in
