Curvature-induced expulsion of actomyosin bundles during cytokinetic ring contraction
Many eukaryotes assemble a ring-shaped actomyosin network that contracts to drive cytokinesis. Unlike actomyosin in sarcomeres, which cycles through contraction and relaxation, the cytokinetic ring disassembles during contraction through an unknown ...

PAIR: Reconstructing Single‐Cell Open‐Chromatin Landscapes for Transcription Factor Regulome Mapping
scATAC‐seq analysis is often constrained by limited sequencing depth, extreme sparsity, and pervasive technical missingness. PAIR is a probabilistic framework that restores scATAC‐seq accessibility profiles by directly modeling the native cell–peak bipartite structure of chromatin accessibility.

Atlas of Plasmodium falciparum intraerythrocytic development using expansion microscopy
Apicomplexan parasites exhibit tremendous diversity in much of their fundamental cell biology, but study of these organisms using light microscopy is often hindered by their small size.

The central spindle regulates cleavage furrow formation and cytokinesis and is composed of antiparallel microtubules bundled by microtubule-associated proteins and kinesin motors. One key protein in the central spindle is a Rho family GTPase-activating protein, CYK-4/MgcRacGAP, whose target is the subject of two new studies that arrive at divergent ...

The power of many: when genetics met yeasts and high‐throughput
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Identification of novel chondroitin proteoglycans in Caenorhabditis elegans: embryonic cell division depends on CPG-1 and CPG-2. [PDF]
Vertebrates produce multiple chondroitin sulfate proteoglycans that play important roles in development and tissue mechanics. In the nematode Caenorhabditis elegans, the chondroitin chains lack sulfate but nevertheless play essential roles in embryonic ...

Interaction Between Actin and Microtubules During Plant Development
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.

Abscission checkpoint control: stuck in the middle with Aurora B [PDF]
At the end of cell division, the cytoplasmic bridge joining the daughter cells is severed through a process that involves scission of the plasma membrane.

AbstractCytokinesis is a crucial step in the cell division cycle whereby the cell membrane and underlying cortex is remodelled and drawn together to create two new daughter cells. While in many eukaryotic systems this process is accomplished by an actomyosin contractile ring, the protozoan parasite Trypanosoma brucei displays an unusual mechanism for ...

Functional characterization of the diatom cyclin-dependent kinase A2 as a mitotic regulator reveals plant-like properties in a non-green lineage [PDF]
Background: Cyclin-dependent kinases (CDKs) are crucial regulators of cell cycle progression in eukaryotes. The diatom CDKA2 was originally assigned to the classical A-type CDKs, but its cell cycle phase-specific transcription at the G2-to-M phase ...
