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

In the Arabidopsis epidermis, the internal mechanical stress of a cell competes with the external stress to control microtubule behavior, providing a framework to understand the mechanical feedbacks that underlie plant morphogenesis.

Signals from major hormones and the environment are integrated in the Arabidopsis hypocotyl to control gene expression and plant stem elongation.

Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.

Genetic and bioinformatic analyses uncover an unexpected role for codon usage biases in regulating gene expression at the transcriptional level by suppressing premature transcription termination.

In the model plant Arabidopsis thaliana genome dynamic exchanges of histone variants control the organization of histone modifications into chromatin states, acting as molecular landmarks.

Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.
