SWI/SNF chromatin remodeling complexes act as ‘gatekeepers’ for auxin responses and directly interact with the auxin response factor MONOPTEROS.

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.

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.

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

Genetic analyses reveal that the TIR1/AFB auxin receptors have broadly overlapping functions throughout plant development, but that the AFB1 receptor has a specialized role in a rapid auxin response.

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