The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

Transgenic analysis reveals a role for LEAFY in ferns that supports a trajectory from general to floral meristem-specific function as land plants evolved.

Polymorphic residues of a vacuolar Ca²⁺ sensor site in TPC1 channels differ between species of Brassicacea and Fabaceae and lead to distinct TPC1 gating behavior.

An ancient and conserved genetic mechanism for cell differentiation is under distinct negative regulation in different lineages of land plants.

The natural history of the model fern Ceratopteris richardii provides opportunities for unique studies and makes it an important system to include in comparative work.

To effectively ward off some of the most damaging groups of filamentous pathogens, plants rely on an evolutionarily conserved syntaxin function to block the pathogen from entering the host cell and proliferate.

The ancestral mechanism to activate diploid gene expression via homeodomain transcription factors was retained in liverworts, an early diverging land plant lineage, and subsequently co-opted during evolution of the diploid sporophyte body.

Analysis of the Arabidopsis V-ATPase reveals convergent evolution of differential targeting as well as redundancy of the endosomal and vacuolar isoforms during vegetative development.

Genetic, biochemical, and bioinformatic analyses reveal how expanding metabolic repertoire interferes with fundamental processes like protein synthesis inside cells and the role of D-aminoacyl-tRNA deacylase2 in protecting these processes during terrestrialisation.

The body plan of the 407-million-year-old plant fossil Asteroxylon mackiei comprised three developmentally distinct systems of axes.
