GNOM controls both auxin transport and auxin signaling to coordinate tissue cell polarity during vein patterning in plants.

In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.

Top-bottom patterning of leaves is not specified by an asymmetry in the distribution of the plant hormone auxin, in contrast to a previous proposal.

The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

Two protein kinases are required to activate auxin efflux transporters from plants.

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

Auxin binding to the ETTIN transcription factor disrupts the interaction between ETT and a TPL/TPR co-repressor and subsequently affects chromatin dynamics to ensure proper gynoecium development.

Auxin is produced in the endosperm after fertilization and drives the development of the seed coat in Arabidopsis.

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

Vacuolar morphologenesis correlates with cell size and is required for auxin-dependent inhibition of growth.
