Mechanistic modelling of coupled phloem/xylem transport for L-systems: combining analytical and computational methods. [PDF]

Ann Bot, 2018
Transport of carbohydrates and water are essential aspects of plant function. The aim of this study was to develop and test the methods for mechanistic modelling of quasi-stationary coupled phloem/xylem transport in the context of functional-structural ...

Perspectives on the Biophysics of Xylem Transport

, 2005
This 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 ...

A vacuolar hexose transport is required for xylem development in the inflorescence stem

Plant Physiology, 2021
International audienceAbstract In Angiosperms, the development of the vascular system is controlled by a complex network of transcription factors. However, how nutrient availability in the vascular cells affects their development remains to be addressed.

Evolution of Xylem Lignification and Hydrogel Transport Regulation [PDF]

Proceedings of the National Academy of Sciences, 2014
In vascular plants, the polysaccharide-based walls of water-conducting cells are strengthened by impregnation with the polyphenolic polymer lignin.

Highly efficient xylem transport of arsenite in the arsenic hyperaccumulator Pteris vittata [PDF]

New Phytologist, 2008
The hyperaccumulator Pteris vittata translocates arsenic (As) from roots to fronds efficiently, but the form of As translocated in xylem and the main location of arsenate reduction have not been resolved. Here, P.

Xylem functioning, dysfunction and repair: a physical perspective and implications for phloem transport

Tree Physiology, 2019
Xylem and phloem are the two main conveyance systems in plants allowing exchanges of water and carbohydrates between roots and leaves. While each system has been studied in isolation for well over a century, the coupling and coordination between them ...

Logistics of water and salt transport through the plant: structure and functioning of the xylem

Plant, Cell and Environment, 2003
The xylem is a long-distance transport system that is unique to higher plants. It evolved into a very sophisticated plumbing system ensuring controlled loading/unloading of ions and water and their effective translocation to the required sinks. The focus

Transport in a coordinated soil-root-xylem-phloem leaf system

Advances in Water Resources, 2018
International audienceLinks between the carbon and water economies of plants are coupled by combining the biochemical demand for atmospheric CO2 with gas transfer through stomates, liquid water transport in the soil-xylem hydraulic system and sucrose ...

Maintenance of xylem Network Transport Capacity: A Review of Embolism Repair in Vascular Plants

Frontiers in Plant Science, 2013
Maintenance of long distance water transport in xylem is essential to plant health and productivity. Both biotic and abiotic environmental conditions lead to embolism formation within the xylem resulting in lost transport capacity and ultimately death ...
