The shoot meristem becomes domed in shape during floral transition and this is controlled by flowering pathways and the phytohormone gibberellin causing increases in cell size and number.
Mechanical stress promotes the expression of the homeobox gene and meristem master regulator STM, synergistically and independently from auxin depletion.
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.
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.
Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.
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 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.
A stochastic model of phyllotaxis can explain the striking irregularities observed in the spiral patterns of plants and predicts that perturbation patterns provide key information about the underlying biochemical mechanisms.
