Co-segregation of recombinant chromatids maintains genome-wide heterozygosity in an asexual nematode

The study shows that genome-wide heterozygosity in the asexual nematode Mesorhabditis belari is maintained through directed assortment of recombinant chromatids during female meiosis.

Evolutionary divergence of anaphase spindle mechanics in nematode embryos constrained by antagnonistic pulling and viscous forces

The paper investigates spindle mechanics in nematode embryos, finding that spindle mobility is constrained by a tradeoff between cytoplasmic viscosity and pulling forces across species.

Why would parthenogenetic females systematically produce males who never transmit their genes to females?

The paper investigates a reproductive strategy in the nematode Mesorhabditis belari where parthenogenetic females produce males that do not pass on their genes to females, and shows this strategy is efficient if sons mate with their sisters.

LET-99-dependent spatial restriction of active force generators makes spindle’s position robust

The paper shows that LET-99 restricts force generators to a posterior crescent, making spindle positioning robust despite variations in force generator numbers.
