Arabidopsis boron transporter for xylem loading

Nature, 2002
Boron deficiency hampers the productivity of 132 crops in more than 80 countries. Boron is essential in higher plants primarily for maintaining the integrity of cell walls and is also beneficial and might be essential in animals and in yeast. Understanding the molecular mechanism(s) of boron transport is crucial for alleviating boron deficiency.

Uptake and Xylem Transport of Fipronil in Sunflower

Journal of Agricultural and Food Chemistry, 2006
The phenylpyrazole insecticide, fipronil, is used in seed coating against Agriotes larvae, which infest mainly corn and sunflower. Coating the seeds of the cultivated plants with fipronil has proven its effectiveness against Agriotes populations. In the case of sunflower or even corn, the possible root uptake of this insecticide may lead to a toxic ...

Modelling phloem and xylem transport within a complex architecture

Functional Plant Biology, 2008
The function of the plant’s vasculature, incorporating both phloem and xylem, is of fundamental importance to the survival of all higher plants. Although the physiological mechanism involved in these two transport pathways has been known for some time, quantitative modelling of this has been slow to develop.

Physiology of Xylem Transport

1995
Root hairs of absorbing roots grow in the cavities of the soil, from where they obtain water and ions solubilised in it (Fig. 29.1). Water transport from the soil into the vessels of the central cylinder of the root occurs in the fluid phase and is driven by differences in water potential. The path of the water from the perirhizal zone into the vessels

Ultrastructure of xylem parenchyma cells of barley roots in relation to ion transport to the xylem

Planta, 1974
The structure of xylem parenchyma cells is examined in relation to transport of ions through the root. Measurement of uptake of (86)Rb(+) and its transport through the root at different distances from the apex show that this is a general activity along the length of the root and not confined to a limited region.
