Interaction of Phloem and Xylem During Phloem Loading: Functional
Symplasmic Roles for Thin- and Thick-Walled Sieve Tubes in Monocotyledons
C. E. J. Botha The phloem in monocotyledons differs from that found in leaves of
dicotyledons and eudicotyledons in that two distinct sieve tube types are
recognized in intermediate and small vascular bundles. These are the early
metaphloem sieve elements, which are characterized by their association with
companion cells, and a ...

Along the phloem path, assimilates are exchanged passively from the transport
phloem through symplasmic routes or directly to the phloem apoplasm (wavy line
). Assimilates leaked to the phloem apoplasm are actively retrieved into the se—
cc complexes (6). On reaching a sink tissue, assimilates and water are unloaded
from the release phloem commonly by symplasmic movement to the surrounding
vascular parenchyma cells (vasc. par.). During subsequent symplasmic transport

The significance of the apoplast for the mineral nutrition of higher plants Burkhard
Sattelmacher, Walter J. Horst ... The isolation procedure developed for the patch
clamp experiments was employed to separate c-DNA from vascular strands from
that of mesophyll cells and of epidermis cells. Physiological ... Nutrient transport
from the soil to the symplasm of leaves occurs through a long apoplastic
compartment: the xylem; these vascular strands extend from the roots to the

Table 1 suggests that the spacing of leaf vascular bundles is generally at least as
close as in otherwise comparable C, plants. The relation between the spacing of
vascular bundles and the rate of photosynthesis in C4 plants can be analysed in
the same way as for Ci plants above. In at least ... plants. The discussion thus far
of sucrose transport from photosynthetic cells to phloem conduits involves the
implicit assumption that the flux, whether apoplasmic or symplasmic, is by

(only) on the sieve tube side; whilst plants of Group III have only sucrose in the
phloem (no other oligosaccharides present) and their companion cells are both
modified into transfer cells and symplasmically isolated from the surrounding
vascular tissue. Gamalei envisages that plants of Group I, to which the
Cucurbitaceae belong, probably have an entirely symplasmic mode for the
transfer of raffinose-type oligosaccharides into the phloem, while sucrose may
move either via the ...

Symplasmic transport of organic C (as well as of N, P and Fe) from sterile regions
to the sporangia is common in extant organisms, where inter alia the lower
photosynthetic capacity of sporangia reduces oxygen production there with a
corresponding smaller risk of free radical damage to the germ-line (Raven et al.,
1994) ... This poses a problem for nutrient solute supply to early vascular plants
in view of the low diffusion coefficient for many solutes (especially phosphate) in
many soils.

However, there can be no doubt that the symplasm plays a vital role in short-
distance transport. This is also evident from the autoradiograms of transport
through bundle bridges where it can be seen that after passage throughout the
vascular system considerable amounts of chloride move into the parenchyma (
Fig. 2.8). c) Drosera. Another system used by Arisz is the tentacle of the
carnivorous plant Drosera capensis (see Helder, 1967b). The tentacle stalk
consists of a xylem vessel ...
