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.

Auxin Transport and in vitro Auxin Binding
1974The plant hormone 3-indole acetic acid (IAA) is actively transported through coleoptile tissue (GOLDSMITH, 1969) and at the same time plays a regulatory role in at least two transport systems: proton secretion is promoted by hormone application (RAYLE, 1973) and auxin transport itself can also be modified by its substrate (HERTEL and FLORY, 1968). This

Intercellular Transport of Auxin
2014Auxin is an essential hormone that regulates both programmed and plastic plant development. The mechanisms that regulate auxin metabolism, transport and signal transduction are well characterized, although important unresolved questions remain.

The dynamics of auxin transport
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1980The plant hormone auxin is transported with a well defined velocity through many tissues. To explain this, one type of theory proposes that a polar mechanism operates at the interface between two cells. I show that, if auxin diffuses freely through the interior of cells, then there is an upper limit to the velocity that can be achieved by such a ...

Auxin transport — shaping the plant
Current Opinion in Plant Biology, 2003Plant growth is marked by its adaptability to continuous changes in environment. A regulated, differential distribution of auxin underlies many adaptation processes including organogenesis, meristem patterning and tropisms. In executing its multiple roles, auxin displays some characteristics of both a hormone and a morphogen. Studies on auxin transport,

Gravity Factor for Auxin Transport [PDF]
The elongating internodes of the axis of a vigorous dicotyledonous plant develop strong curvatures if the tropistic effect of gravity is eliminated on a clinostat. Similar curvatures are produced by unbalancing either the supply of auxin or its transport paths, but only in the absence of unidirectional gravity as a distributive force.

The specificity of the auxin transport system
Planta, 1969In an effort to examine the specificity of the auxin transport system, the movement of a variety of growth substances and of auxin analogues through corn coleoptile sections was measured in both the basipetal and acropetal directions. In contrast to the basipetal, polar transport of the auxins indoleacetic acid (IAA) and 2,4-dichlorophenoxyacetic acid,

The phytohormone auxin is of fundamental importance in plant development. Since the identification of auxin as a plant growth substance, auxin transport has drawn considerable research attention. Intercellular (polar) auxin transport contributes to its graded distribution in cell files or entire organs and allows for dynamic, environmentally controlled

The induction of transport channels by auxin
Planta, 1975This work deals with measurements of the transport of radio-activity from [(3)H] indole acetic acid during early stages of auxin-induced vascular differentiation. Transverse wounds were made in stems of Phaseolus vulgaris L. and the radioactivity which was transported around these wounds was measured.
