The pathways of calcium movement to the xylem
Webb14 maj 2024 · Once in the xylem, water with the minerals that have been deposited in it (as well as occasional organic molecules supplied by the root tissue) move up in the vessels and tracheids. At any level, the water can leave the xylem and pass laterally to supply the needs of other tissues. WebbThe pathways of calcium movement to the xylem. P. White Environmental Science Journal of experimental botany 2001 TLDR It is noted that a quantity of purely apoplastic Ca2+ transport to the xylem is indicated, which would enable the root to fulfil the demand of the shoot for calcium without compromising intracellular [Ca2+]cyt signals. 377 PDF
