This valuable study concerns a model for transgenerational epigenetic inheritance, the learned avoidance by C. elegans of the PA14 pathogenic strain of Pseudomonas aeruginosa. A recent study questioned whether transgenerational inheritance in this paradigm lacks robustness. The authors of this study have worked independently of the group that reported the original phenomenon and also independently of the group that challenged the original report. With solid data, this study independently validates findings previously reported by the Murphy group, confirming that the paradigm is reproducible elsewhere. The present study is therefore of broad interest to anyone studying genetics, epigenetics, or learned behavior.
