Genetics, and not diet, drives DNA methylation in the water strider Microvelia longipes

Mirjam Urb, Séverine Viala, Juliette Mendes, Abderrahman Khila

The study shows DNA methylation in water striders is genetically driven, not environmentally induced, challenging the role of methylation in phenotypic plasticity.

Nutrition mediates extreme growth variation through deep changes in gene expression in the water strider Microvelia longipes

Ingrid Dourlens, Séverine Viala, Kiran Padmanabhan, Abderrahman Khila

The paper shows nutrition drives gene expression changes leading to extreme growth variation in male water strider legs, with BMP11 playing a key role in mediating this effect.

Sexual conflict, directional sexual selection and phenotypic plasticity jointly drive the evolution of extreme phenotypic variation

Claudia Pruvôt, Arnaud Badiane, Ingrid Dourlens, Mariama Drame, Juliette Mendes, Mirjam Urb, Romain Vedie, Séverine Viala, Cristina P Vieira, Patricia Gibert, Abderrahman Khila

The paper shows that sexual conflict and directional sexual selection, combined with phenotypic plasticity, maintain high phenotypic variation in male water striders.

The genome of the water strider Gerris buenoi reveals expansions of gene repertoires associated with adaptations to life on the water

David Armisén, Rajendhran Rajakumar, Markus Friedrich, Joshua B. Benoit, Hugh M. Robertson, Kristen A. Panfilio, Seung‐Joon Ahn, Monica F. Poelchau, Hsu Chao, Huyen Dinh, HarshaVardhan Doddapaneni, Shannon Dugan, Richard A. Gibbs, Daniel Hughes, Yi Han, , Abderrahman Khila

The paper reports the sequencing and manual annotation of the Gerris buenoi genome, identifying gene expansions linked to adaptations for aquatic life.
