Vesicular cycling mechanisms that control auxin transport polarity
Trends in Plant Science, 2003The polar transport of auxin controls many important plant growth and developmental processes. The polarity of auxin movement has long been suggested to be mediated by asymmetric distribution of auxin transport proteins, yet, until recently, little was known about the mechanisms that establish protein asymmetry in auxin-transporting cells.

Polar auxin transport: controlling where and how much
Trends in Plant Science, 2001Auxin is transported through plant tissues, moving from cell to cell in a unique polar manner. Polar auxin transport controls important growth and developmental processes in higher plants. Recent studies have identified several proteins that mediate polar auxin transport and have shown that some of these proteins are asymmetrically localized, paving ...

The importance of the plant growth regulator auxin for plant growth has long been recognized, even before the discovery of its chemical structures in the early 20th century. Physiological studies in the decades since have demonstrated that auxin is unidirectionally transported in plants, a process dubbed polar auxin transport.

Transmembrane auxin carrier systems – dynamic regulators of polar auxin transport
Plant Growth Regulation, 2000Recent investigations of the biochemistry, physiology and molecular genetics of polar auxin transport have greatly advanced our understanding of the process and of the part it plays in the regulation of development and in the responses of cells, tissues and organs to internal and external stimuli.

Plant Competition: Light Signals Control Polar Auxin Transport
2013Plants typically grow at high densities in natural vegetations and agricultural fields, where they interact with their neighbours to compete for limited resources, and respond with morphological acclimations that facilitate resource capture. A well-studied example of aboveground responses to neighbours is the shade avoidance syndrome (SAS), which is ...

Hormonal Control of Polar Auxin Transport
2013Polar auxin transport (PAT) is required for the formation and maintenance of local auxin gradients, which is of crucial importance for many aspects of auxin-mediated plant development. Different plant hormones regulate plant growth and development mostly by modulating PAT, particularly, pointing to the PINFORMED (PIN) proteins. In this book chapter, we

Reversible, covalent modification by the small protein ubiquitin acts in a variety of pathways controlling protein fate in virtually all aspects of cellular function. For example, ubiquitylation of plasma membrane proteins modulates their intracellular sorting and turnover, thereby decisively influencing crosstalk between cells and their environment ...

Feedback models for polarized auxin transport: an emerging trend
Molecular BioSystems, 2011The phytohormone auxin is vital to plant growth and development. A unique property of auxin among all other plant hormones is its cell-to-cell polar transport that requires activity of polarly localized PIN-FORMED (PIN) auxin efflux transporters. Despite the substantial molecular insight into the cellular PIN polarization, the mechanistic understanding

Current Opinion in Plant Biology, 2017
Directional cell-to-cell transport of functional molecules, called polar transport, enables plants to sense and respond to developmental and environmental signals. Transporters that localize to plasma membranes (PMs) in a polar manner are key components of these systems. PIN-FORMED (PIN) auxin efflux carriers, which are the most studied polar-localized
