Mutant and gene expression analyses shows that phytohormones and mobile transcription factors interact to coordinate organ formation with stem cell maintenance in the plant shoot meristem.

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

Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.

TOR kinase guides the transition of plant stem cells from the dormant embryonic state to the active adult state by integrating light and metabolic signals.

HEC transcription factors control the timing of cell fate transitions in a dynamic stem cell system, allowing plants to adapt their developmental program to diverse environments.

Leaf position, shape and orientation are pre-patterned by cell type boundaries in the shoot meristem.

The maize CLAVATA receptor, FEA2, functions in the perception of two different ligands, and remarkably that signaling from these different inputs is differentiated by the receptor interacting with two different downstream components.

Models that generate tandem alignments of cell polarities are more readily compatible with the formation of PIN1 polarity patterns in plant leaf buds than the most widely accepted “up-the-gradient” model.

Mechanical stress promotes the expression of the homeobox gene and meristem master regulator STM, synergistically and independently from auxin depletion.

The hormonal circuitry controlling development in plants can be studied and re-programmed with hormone activated Cas9-based repressors.
