Dye-tracer-aided investigation of xylem water transport velocity distributions [PDF]

open access: yesHydrology and Earth System Sciences, 2023
The vast majority of studies investigating the source depths in the soil of root water uptake with the help of stable water isotopes implicitly assumes that the isotopic signatures of root water uptake and xylem water are identical. In this study we show

Diurnal Changes in the Transport Rates of Ureides, Amides, Cations, Anions, and Organic Acids Estimated by Xylem Sap Exudate and the Water Flow Rate of Soybean Plants [PDF]

open access: yesPlants
Ureides; allantoate, allantoin, and amides; asparagine, and glutamine are the N2 fixation products in soybean root nodules, and they are transported through xylem vessels.

NUT1-Exo70A1 Regulates Xylem Vessel Development and Influences Water Use Efficiency in Maize [PDF]

open access: yesNature Communications
Efficient water uptake and transport through xylem vessels are essential for plant growth and development. The patterned secondary cell wall (SCW) structure of xylem vessels provides robust mechanical support to withstand the strong negative pressure ...

Scaling of xylem and phloem transport capacity and resource usage with tree size

open access: yesFrontiers in Plant Science, 2013
Xylem and phloem need to maintain steady transport rates of water and carbohydrates to match the exchange rates of these compounds at the leaves. A major proportion of the carbon and nitrogen assimilated by a tree is allocated to the construction and ...

On the Efficacy of Water Transport in Leaves. A Coupled Xylem-Phloem Model of Water and Solute Transport

open access: yesFrontiers in Plant Science, 2021
In this paper, we present and use a coupled xylem/phloem mathematical model of passive water and solute transport through a reticulated vascular system of an angiosperm leaf.

Maintenance of xylem network transport capacity: a review of embolism repair in vascular plants

open access: yesFrontiers 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 ...

Vertical Stratification Drives Divergent Spatial Trade‐Offs Among Xylem Cell Types in Angiosperm Trees of a Mountain Forest in Eastern China [PDF]

open access: yesEcology and Evolution
Vertical stratification in forests acts as an ecological filter, driving woody plants to evolve specialized survival strategies. Angiosperms, in particular, develop secondary xylem with three interdependent functions—water transport, mechanical support ...

A node-localized efflux transporter for loading iron to developing tissues in rice [PDF]

open access: yesNature Communications
Iron (Fe) is an essential micronutrient for plant growth and development. It plays crucial roles in various organs and tissues of plants, but the molecular mechanisms governing its distribution to the above-ground parts after root uptake remain unclear ...

Absorption and Transport of Phosphorus in Nodulated Soybean Plants and Diagnosis of Phosphorus Status Using Xylem Sap Analysis

open access: yesAgriculture
Phosphorus (P) is an essential major element for plants. The absorption and transport of P are important for soybean growth and yield, including nodule growth and N2 fixation. Through an analysis of xylem sap, we investigated how nodulated soybean plants

The effects of rising atmospheric carbon dioxide on shoot-root nitrogen and water signaling. [PDF]

open access: yes, 2013
Terrestrial higher plants are composed of roots and shoots, distinct organs that conduct complementary functions in dissimilar environments. For example, roots are responsible for acquiring water and nutrients such as inorganic nitrogen from the soil ...
