A Maternal-Effect Toxin Affects Epithelial Differentiation and Tissue Mechanics in Caenorhabditis elegans

C. Lehmann and C. Pohl,  Frontiers in Cell and Developmental Biology,  9. 2021.
Selfish genetic elements that act as post-segregation distorters cause lethality in non-carrier individuals after fertilization. Two post-segregation distorters have been previously identified in Caenorhabditis elegans, the peel-1/zeel-1 and the sup-35/pha-1 elements. These ...

Ubiquitous Selfish Toxin-Antidote Elements in Caenorhabditis Species

E. Ben-David, P. Pliota, S. A. Widen, A. Koreshova, T. Lemus-Vergara, P. Verpukhovskiy, S. Mandali, C. Braendle, A. Burga and L. Kruglyak,  Current Biology,  2021.
Here, we report the discovery of maternal-effect TAs in both C. tropicalis and C. briggsae, two distant relatives of C. elegans. In C. tropicalis, multiple TAs combine to cause a striking degree of intraspecific incompatibility: five elements reduce the fitness of >70% of the ...

A maternal-effect selfish genetic element in Caenorhabditis elegans

E. Ben-David, A. Burga and L. Kruglyak,  Science,  356:1051. 2017.
We discovered a selfish element causing embryonic lethality in crosses between wild strains of the nematode Caenorhabditis elegans.

Poisons, antidotes, and selfish genes

N. Phadnis,  Science,  356:1013. 2017.
On page1051 of this issue, BenDavid et al . (3) chase down a serendipitous observation of an anomaly in genetic crosses to unmask a toxin-antidote type of selfish system in worms.
