Leaf vein patterning is regulated by the aperture of plasmodesmata intercellular channels
To form tissue networks, animal cells migrate and interact through proteins protruding from their plasma membranes. Plant cells can do neither, yet plants form vein networks.

Advances in the Biological Functions of Auxin Transporters in Rice
Auxin is the earliest discovered plant hormone, which plays important roles in each aspect of plant growth and development. There are two main pathways for auxin to be transported from the synthetic site (such as young leaves and terminal buds) to the ...

The Transportable Auxin Pool [PDF]
Evidences from experiments with stem sections of sunflower seedlings suggest that the transport of auxin may be limited by a restricted pool size of transportable auxin and restrictions in the availability of transport sites. A steady state of transport is observed over a range of lengths of stem sections, and over a wide range of auxin contents.

AbstractThe signaling molecule auxin is intimately associated with morphogenic processes in plants but how it influences pattern formation has been unclear. Recent studies by Friml et al. (2003), Benková et al. (2003), and Reinhardt et al. (2003) have elegantly illustrated that auxin transport plays a key role during embryonic, root, and shoot ...

Connective auxin transport contributes to strigolactone-mediated shoot branching control independent of the transcription factor BRC1. [PDF]
The shoot systems of plants are built by the action of the primary shoot apical meristem, established during embryogenesis. In the axil of each leaf produced by the primary meristem, secondary axillary shoot apical meristems are established.

Polar Auxin Transport and Asymmetric Auxin Distribution [PDF]
In all multicellular organisms extensive communication is required between cells and tissues in order to coordinate growth and development. Both plants and animals have signaling chemicals, traditionally termed hormones that mediate short- and long-distance communication.

Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

Experiments on the Transport of Auxin [PDF]
1. Adapting the photokymograph recording of the Avena test, a new technique for measuring the velocity and capacity of the transport of growth promoting substances through different tissues has been worked out. For this the rate of bending and the moment of beginning of curvatures are compared for a normal Avena test and one in which the agar block is ...

Single-cell-based system to monitor carrier driven cellular auxin homeostasis [PDF]
Background: Abundance and distribution of the plant hormone auxin play important roles in plant development. Besides other metabolic processes, various auxin carriers control the cellular level of active auxin and, hence, are major regulators of cellular

CLASPing Microtubules and Auxin Transport [PDF]
The role, if any, of microtubules in auxin transport is poorly understood in plant biology. In this issue of Developmental Cell, Ambrose et al. (2013) show that the microtubule binding protein CLASP regulates PIN2 auxin transporter trafficking and stability via Sorting Nexin1, a component of the retromer complex.
