ZW and XY Sex Chromosomes Drive Rapid and Distinctive Evolution of Sex‐Biased Gene Expression

Molecular Ecology, EarlyView.
ABSTRACT Cichlids are a textbook model system of adaptive radiation and a fascinating example of rapid sex chromosome evolution. Yet in these fish, as in most other taxa, the mechanisms causing sex chromosome turnover and the subsequent impact thereof are unknown.

DNA methylation contributes to plant acclimation to naturally fluctuating light

New Phytologist, EarlyView.
Summary Plants in the natural environment experience continuous dynamic changes in light intensity. Here, we exposed Arabidopsis thaliana plants to naturally fluctuating light (FL) regimes alongside traditional square light (SQ) regimes such as those often found in control environment growth chambers.

Multiple hybrid zones involving four Cardamine species and their triploid progeny: watching allopolyploid speciation in action?

New Phytologist, EarlyView.
Summary Hybrid zones provide excellent opportunities to study evolutionary processes linked to interspecific gene flow, including introgression, genetic erosion, polyploid establishment, and speciation. The genus Cardamine (Brassicaceae) serves as an excellent model for polyploid evolution, including one of the few well‐documented neo‐allopolyploid ...

Longevity in plants impacts phylogenetic and population dynamics

New Phytologist, EarlyView.
Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.
