The pathways of calcium movement to the xylem
Webb30 mars 2024 · Delineating quiescence and dormancy. Quiescence (noun) is a labile state of a cell, embryonic or meristematic structure, where division of the cell or cell population is repressed by non-cell-autonomous processes. Cell division may not have ceased or stalled, and evidence suggests that mitosis continues even in stem cell populations. 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
