The apoplastic tracers Cellufluor and lanthanum nitrate, and the symplastic tracer uranin, were used to study pathways for transport in leaves and roots of the seagrass Halodule uninervis (Forssk.) Aschers. An apoplastic pathway was shown to exist in most leaf tissues except in the region of ...
SHR and miR165 Move via the Symplastic Pathway In addition to impaired formation of the phloem, xylem identity was unstable in the cals3-d mutants. In wild-type, protoxylem cells are distinguished by their position in the stele and their ring-like cell wall thickenings (open arrowheads in ...
symplastic and apoplastic pathwaysEfficient delivery of nanoparticles (NPs) to plants is important for agricultural application. However, to date, we still lack knowledge about how NPs' charge matters for its translocation pathway, i.e., symplastic and apoplastic pathways, in plants. In this study,...

Sorbitol and sucrose are the two main soluble carbohydrates in mature peach leaves. Both are translocated in the phloem, in peach as in other rosaceous trees. The respective role of these two soluble carbohydrates in the leaf carbon budget, and their phloem loading pathway, remain poorly ...
apoplastic pathwaysymplastic pathwayTo capture prey, Utricularia gibba, an aquatic angiosperm carnivorous plant, is equipped with specialized bladders containing bifid/quadrifid glands for nutrient absorption. Several studies have focused on the nutrient absorption and subsequent transportation in the ...
These finding showed that carbohydrates are transported mainly in the form of sucrose, and more than 54.6% was present in the stem phloem. Sucrose was predominantly unloaded symplastically from the phloem into storage roots; in addition, there was a shift from apoplastic to symplastic unloading ...
Evidence was obtained that an apoplastic barrier exists in the anticlinal walls of the stalk cell, and is taken to indicate that a flow of pre-nectar, equivalent in volume to the nectar that is secreted from the apex of the trichome, passes through the stalk cell protoplast. In terms of ...
The apparent Arrhenius activation energies for apoplastic and symplastic uptake are 77.5 and 9.39KJmol1, respectively. The symplastic uptake accounts for over 55% of total phenanthrene uptake, suggesting that symplast is the dominant pathway for wheat root phenanthrene uptake. Larger volume of symplast...
