Monitoring Xylem Transport in Arabidopsis thaliana Seedlings Using Fluorescent Dyes
2023Fluorescent dyes are often used to observe transport mechanisms in plant vascular tissues. However, it has been technically challenging to apply fluorescent dyes on roots to monitor xylem transport in vivo. Here, we present a fast, noninvasive, and high-throughput protocol to monitor xylem transport in seedlings.

A pericycle‐localized silicon transporter for efficient xylem loading in rice
New Phytologist, 2022Summary Rice is able to accumulate high concentrations of silicon (Si) in the shoots, and this ability is required for the mitigation of abiotic and biotic stresses. Although transporters for Si uptake have been identified, a transporter for the xylem loading of Si has not been found.

Evolution of Water Transport and Xylem Structure
International Journal of Plant Sciences, 2003Land plants need water to replace the evaporation that occurs while atmospheric CO2 is diffusing into photosynthetic tissue. The water‐for‐carbon exchange rate is poor, and evolutionary history indicates a progression of innovations for cheap water transport—beginning in order with capillary suction at cell walls, stomatal regulation, hydroids ...

Effect of leaf water status and xylem pH on metabolism of xylem-transported abscisic acid
Plant Growth Regulation, 1997Metabolism and distribution of xylem-fed ABA were investigated in leaves of maize (Zea mays) and Commelina communis when water stress and xylem pH manipulation were applied. 3H-ABA was fed to excised leaves via the transpiration stream. Water stress was applied through either a previous soil-drying before leaves were excised, or a quick dehydration ...

Perspectives on the Biophysics of Xylem Transport
2005This chapter provides a brief discussion on cohesion-tension theory. The chapter also focuses on factors that affect hydraulic resistance in plants. It addresses how sap is extruded into the empty tracheary element even though the free energy gradient from soil to xylem seems often to be in the wrong direction, how the element is hydraulically isolated

1989
Publisher Summary Xylem perfusion is the use of pressure or suction to bring about the flow of an artificial solution through xylem vessels in an excised root or shoot segment. The advantages of a perfusion system are control over the composition of the solution entering the xylem vessels, ability to bring hormones and specific inhibitors into direct

Water transport in xylem conduits with ring thickenings
Plant, Cell & Environment, 1996ABSTRACTHelical or annular wall thickenings are not only present in protoxylem, but may also he a feature of the tracheids or vessel elements of secondary wood. The frequency of their occurrence tends to be a function of climatic factors and conduit diameter.

Xylem and phloem transport of micronutrients
2001Knowledge on xylem, and especially phloem transport of micronutrients is important in developing our capacity to enhance loading of micronutrients into developing grain (which has consequences for human nutrition), to increase nutrient-use efficiency through increased remobilisation and re-utilisation of nutrients, to effectively nourish seedlings in ...

Waterlogging affects nitrogen transport in the xylem of soybean
Plant Physiology and Biochemistry, 1999Abstract Transfer of nodulated and non-nodulated plants grown in vermiculite to hydroponic culture without soil was used to study waterlogging and nitrogen transport in the xylem of soybean. Non-aeration, aeration or aeration with nitrogen gas were used to obtain different levels of oxygen in the culture solutions.

Ontogenetic changes in potassium transport in xylem of tomato
Physiologia Plantarum, 1982The influence of plant ontogeny on xylem exudate K+ concentrations and K+ transport to the shoot was studied in both nutrient‐solution and field‐grown tomato plants (Lycopersicon esculentum).K+ concentrations in xylem exudate from decapitated plants decreased during tomato plant development from a high of 12 mM to a low of 5 mM.
