The auxin-sensitive Aux/IAA transcriptional repressors regulate approximately 35% of the annotated genes in Physcomitrella patens and exhibit complex interactions with both the activating and repressing ARF transcription factors.

Lagging chromosomes in anaphase inhibits cytokinesis in plant cells.

The mosses and angiosperms have independently evolved mechanisms that use the same hormones-auxin, cytokinin and strigolactone-to regulate lateral shoot branching.

TALE homeodomain transcription factors have been independently recruited to regulate gametophyte to sporophyte transitions in two complex multicellular eukaryotic supergroups, land plants in Archaeplastida and brown algae in Chromalveolata.

Class VIII myosins mediate crosstalk between actin and microtubules to position cell division in plants.

Conditional genetic inactivation of a highly conserved, ancestral subgroup of 14-3-3 proteins in Arabidopsis thaliana reveals fundamental roles in auxin transport-dependent plant development and post-Golgi trafficking processes.

The plant hormone ethylene regulates the expression of multiple genes in the model plant Arabidopsis, including those that respond to other hormones.

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

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.

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.
