Cortical microtubules oppose actomyosin-driven membrane ingression during C. elegans meiosis I polar body extrusion

This study shows that CLS-2 and related kinetochore proteins stabilize cortical microtubules to limit membrane ingression and enable contractile ring assembly during C. elegans meiosis I polar body extrusion.

C. elegans XMAP215/ZYG-9 and TACC/TAC-1 act at multiple times throughout oocyte meiotic spindle assembly to promote both the coalescence of pole foci into a bipolar structure and the stability of coalesced poles during oocyte meiotic cell division

This study identifies multiple temporally distinct roles of ZYG-9/TAC-1 in C. elegans oocyte meiotic spindle assembly, promoting pole coalescence and stability during both meiosis I and II.

The Chromatin Remodeling Protein CHD-1 and the EFL-1/DPL-1 Transcription Factor Cooperatively Down Regulate CDK-2 to Control SAS-6 Levels and Centriole Number

This paper shows that CHD-1 and EFL-1/DPL-1 transcription factors reduce CDK-2 expression, which increases SAS-6 levels and centriole number in C. elegans embryos.

C. elegans CLASP/CLS-2 negatively regulates membrane ingression throughout the oocyte cortex and is required for polar body extrusion

This study investigates the role of CLASP/CLS-2 in polar body extrusion during C. elegans oocyte meiosis, showing it is required for contractile ring assembly and negatively regulates cortical membrane ingression.

Microtubule Assembly and Pole Coalescence: Early Steps in C. elegans Oocyte Meiosis I Spindle Assembly

The paper investigates the role of the nuclear lamina and microtubule regulators in C. elegans oocyte meiosis I spindle assembly, showing their contributions to microtubule organization and pole coalescence.

Excess crossovers impede faithful meiotic chromosome segregation in C. elegans

This study shows that excess crossovers in C. elegans cause chromosome mispatterning and segregation defects, but these errors are corrected by LEM-3 nuclease and homolog tethers during meiosis.

The tumor suppressor APC is an attenuator of spindle-pulling forces during C. elegans asymmetric cell division

This study identifies APC as an attenuator of spindle-pulling forces during C. elegans asymmetric cell division, showing it stabilizes microtubule plus-ends and reduces catastrophe frequency.
