Xylem refilling – a question of sugar transporters and pH? [PDF]

open access: yesPlant, Cell & Environment, 2016
This article comments on: Accumulation of sugars in the xylem apoplast observed under water stress conditions is controlled by xylem ...

Cargo-dependent and cell wall-associated xylem transport in Arabidopsis.

open access: yesNew Phytologist, 2018
Sap molecules are transported by xylem flow throughout the whole plant body. Factors regulating the xylem transport of different molecules remain to be identified.

Relationships between hydraulic traits and habitat preference for six Acer species occurring in the French Alps [PDF]

open access: yes, 2004
Xylem hydraulic properties and vulnerability to cavitation were studied in six Acer species which occur, in the French Alps, along a soil moisture gradient from the moist valleys to the drier mountain stands.

Hormonal changes in relation to biomass partitioning and shoot growth impairment in salinised tomato (Solanum lycopersicum L.) plants. [PDF]

open access: yes, 2008
Following exposure to salinity, the root/shoot ratio is increased (an important adaptive response) due to the rapid inhibition of shoot growth (which limits plant productivity) while root growth is maintained.

An auxin transport network underlies xylem bridge formation between the hemi-parasitic plant Phtheirospermum japonicum and host Arabidopsis

open access: yesDevelopment, 2019
Parasitic plants form vascular connections with host plants for efficient material transport. The haustorium is the responsible organ for host invasion and subsequent vascular connection.

Transport of Rb and Sr to the ear in mature, excised shoots of wheat: Effects of temperature and stem length on Rb removal from the xylem [PDF]

open access: yes, 1991
Wheat (Triticum aestivum L. cv. `Arina') shoots grown in the field were excised post-anthesis and incubated in the laboratory for 72 h standing in 2 mM RbCl + 2 mM SrCl2. Strontium is a phloem-immobile, xylem-mobile element and indicates the distribution

Distribution of xylem hydraulic resistance in fruiting truss of tomato influenced by water stress

open access: yes, 2003
In this study xylem hydraulic resistances of peduncles (truss stalk), pedicels (fruit stalk) and the future abscission zone (AZ) halfway along the pedicel of tomato (Lycopersicon esculentum L.) plants were directly measured at different stages of fruit ...

Control of xylem Na+ loading and transport to the shoot in rice and barley as a determinant of differential salinity stress tolerance.

open access: yesPhysiologia Plantarum : An International Journal for Plant Biology, 2018
Control of xylem Na+ loading has often been named as the essential component of salinity tolerance mechanism. However, it is less clear to what extent the difference in this trait may determine differential salinity tolerance between species.

Evidence of phloem boron transport in response to interrupted boron supply in white lupin (Lupinus albus L. cv. Kiev Mutant) at the reproductive stage

open access: yes, 2008
The present study investigates whether previously acquired boron (B) in mature leaves in white lupin can be retranslocated into the rapidly growing young reproductive organs, in response to short-term (3 d) interrupted B supply.
