The paper discovers a novel toxin-antidote gene pair in C. nigoni, showing the antidote evolved before the toxin and supports a microbial origin for the toxin.

This paper shows a new F-box gene in C. nigoni causes hybrid incompatibility by degrading a phosphoglucomutase from C. briggsae, leading to embryonic death in hybrids.

This paper improves transgenesis efficiency in C. briggsae by modifying a transposon-based method with a heat shock step, enabling single-copy insertions and applications in hybrid male sterility studies.

The paper characterizes the genomic structure and variation of the 5S rDNA cluster in C. elegans and C. briggsae strains, revealing differences in stability and transcriptional compatibility.

The paper identifies multiple interacting genomic loci responsible for asymmetric hybrid male sterility and inviability between Caenorhabditis briggsae and C. nigoni.
