Building on this assumption, a physically based model that repre- sents the short-term impacts of salinity on plant–water relations and xylem–leaf–phloem hydraulic coupling is proposed. The approach relies on (a) the cohesion–tension theory in the root– plant system, (b) the balance ...
Among the species studied, all the members of Polygonaceae had normal secondary xylem, whereas in Aizoaceae and Chenopodiaceae the vascular cylinder of the mature stem was composed of successive rings of xylem alternating with phloem bands. All the species of Chenopodiaceae and Polygonaceae accumulated ...
and xylem of lateral roots in susceptibleV. fordii(Fig.1d, e), while the hyphae extended only to the phloem in resistantV. montana(Fig.1h, i). At 8 dpi,Fof-1 spread longitudinally to the main roots through the xylem of the lateral root in susceptibleV. fordii. The hyphae were confine...
Sap was extracted using a Scholander pressure chamber from the proximal ends of branches and roots 60–90 cm in length and 1.0–1.5 cm in diameter at the cut in a procedure modified from Stark and Spitzner (1985). Bark, phloem, and the vascular cambial zone were stripped from the ...

plants with RNAi suppression of SlFRK3 as well as plants expressing beta-glucoronidase (GUS) under the SlFRK3 promoter.GUS staining indicated SlFRK3 expression in vascular tissues of the leaves and stems, including cambium, differentiating xylem, young xylem fibers and phloem companion cells. Su...
