Evolution of sex-biased gene expression during transitions to separate sexes in the Silene genus

D. Prentout, A. Muyle, N. Zemp, A. El Filali, B. Boussau, P. Touzet, A. Widmer, J. Kafer, G. A. Marais

This study examines the evolution of sex-biased gene expression during transitions to separate sexes in the Silene genus, showing male-biased genes emerge first and positive selection affects some SBGs.

Sex chromosomes, sex ratios and sex gaps in longevity in plants

G. A. Marais, J.-F. Lemaitre

The paper investigates the relationship between sex chromosomes and sex gaps in longevity in plants using adult sex ratios as a proxy across 43 species.

Philosophical Transactions of the Royal Society B · May 9, 2022Peer-reviewedPlant Biology

Plant genera Cannabis and Humulus share the same pair of well-differentiated sex chromosomes.

D. Prentout, N. Stajner, A. Cerenak, T. Tricou, C. Brochier-Armanet, J. Jakse, J. Kafer, G. A. Marais

The paper identifies shared sex chromosomes between Cannabis and Humulus, showing recombination suppression and Y chromosome degeneration in their common ancestor.
