Alterations of xylem transport of key metabolic products of assimilatory activity in soybean: do similar alterations occur in roots and nodules?
(2022-01-01)
The dynamics of changes in key metabolites of N metabolism were investigated simultaneously in roots, nodules and xylem sap following treatments that turn on and off symbiotic N2 fixation in the nodules and nitrate ...
Root xylem in three woody angiosperm species is not more vulnerable to embolism than stem xylem
(2020-05-01)
Aims: Since plants are compartmentalised organisms, failure of their hydraulic transport system could differ between organs. We test here whether xylem tissue of stems and roots differ in their drought-induced embolism ...
Boron transport in Eucalyptus. 2. Identification in silico of a putative boron transporter for xylem loading in eucalypt
(Sociedade Brasileira de Genética, 2005-01-01)
Boron (B) is a low mobility plant micronutrient whose molecular mechanisms of absorption and translocation are still controversial. Many factors are involved in tolerance to Boron excess or deficiency. Recently, the first ...

Growth and stress conditions cause similar changes in xylem amino acids for different legume species

N-stress alters aspartate and asparagine levels of xylem sap in soybean

Weak tradeoff between xylem safety and xylem-specific hydraulic efficiency across the world's woody plant species
(Wiley Blackwell Publishing, Inc, 2015-09-17)
* The evolution of lignified xylem allowed for the efficient transport of water under tension, but also exposed the vascular network to the risk of gas emboli and the spread of gas between xylem conduits, thus impeding sap ...
Coordination of leaf and stem water transport properties in tropical forest trees
(Springer, 2008-05)
Stomatal regulation of transpiration constrains leaf water potential (ΨL) within species-specific ranges that presumably avoid excessive tension and embolism in the stem xylem upstream. However, the hydraulic resistance ...
Mineral nitrogen associated changes in growth and Xylem-N compounds in amazonian legume tree
(Taylor & Francis Inc, 2015-01-01)
In nodulated young Inga edulis plants, nodule and plant growth, nitrogen (N) in xylem sap and tissues total contents of amino acid, ureide, and nitrate were determined in response to nutrition with nitrate, ammonium, or ...
