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

A meristem acting at the margins of Arabidopsis leaves is suppressed by factors acting primarily in leaves and other determinate organs.

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

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.

Recent reports on the ability of biological molecules to sense magnetic fields are found to be inconsistent with basic physical principles.

A recent claim that humans can discriminate 1 trillion odors is found to be unwarranted, and further analysis offers insights into the dimensionality of olfactory perception.

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.

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.

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

Comparing maize to its wild ancestor teosinte advances our understanding of how it and other cereal crops evolved, and also identifies the genetic variation that can contribute to important agricultural traits.
