Conditional genetic inactivation of a highly conserved, ancestral subgroup of 14-3-3 proteins in Arabidopsis thaliana reveals fundamental roles in auxin transport-dependent plant development and post-Golgi trafficking processes.

Comparative genetics between distant plant species shows that for the PIN auxin transport proteins differential membrane and tissue-level accumulation, transport activity, and interaction result in different functional properties in the shoot post transcription.
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.

Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.
Negative Gravitropic Response of roots (NGRs), pivotal for root gravitropic bending, are indispensable for the gravity-induced translocation of D6 protein kinase, a key regulator of PIN3 auxin efflux carrier activity.

The spatial-temporal computer model of plant root meristem combines biomechanics and biochemical scales to reveal design principles underlying cell polarity and anisotropic growth during root development.
The plant developmental regulator GNOM performs its unique function from the cell periphery, through sequence features present in all its domains, and not by the control of endocytosis.
