      The post-phloem unloading pathway and the mechanism of sugar accumulation remain unclear in litchi fruit. A combination of electron microscopy, transport of phloem-mobile symplasmic tracer (carboxyfluorescein, CF) and biochemical and molecular assays was used to explore the post-phloem transport pathway and the mechanism of aril sugar.

Phloem unloading and post-phloem transport in developing wheat grains by Ning Wang Download PDF EPUB FB2

Phloem unloading and post-phloem transport in developing wheat (Triticum aestivum L.) grains were investigated by perfusing the endosperm cavities of attached grains. Relative unloading ratio (RUR) and the rate of sucrose release into the endosperm cavity (SRR) were calculated, respectively, from 14C import and from sucrose washout from the by:   A variety of fluorescent tracers and proteins were injected via severed aphid stylets into the sieve tubes of wheat (Triticum aestivum L.) grains to evaluate the dimensions of plasmodesmal channels involved in sieve element/companion cell (SE/CC)unloading and post-phloem transport.

In the post-phloem pathway, where diffusion is the predominant mode of. Robert Turgeon, Brian G. Ayre, in Vascular Transport in Plants, Phloem loading can only be understood by detailed examination of the routes of sugar movement from mesophyll cells to sieve elements.

Mapping these routes and determining the mode of transport at different interfaces are challenging, as the pathways are complex, the distances short, and the.

Plant Physiol. ;– PubMed Google ScholarCited by:   Macromolecular trafficking within the sieve element–companion cell complex, phloem unloading, and post-phloem transport were studied using the jellyfish green fluorescent protein (GFP).

The GFP gene was expressed in Arabidopsis and tobacco under the control of the AtSUC2 promoter. In wild-type Arabidopsis plants, this promoter regulates expression of the Cited by: Phloem unloading and post-phloem transport in developing wheat (Triticum aestivum L.) grains were investigated by perfusing the endosperm cavities of attached grains.

Furthermore, the GFP was unloaded in sink tissues, such as root tips, anthers, and developing leaves, and was transported subsequently through non-phloem tissues. These are watershed findings in that they indicate that plasmodesmata along the post-phloem pathway in sink tissues may accommodate the transport of relatively large by: Along the pathway between source and sink, concentrations and composition of the phloem sap may change considerably for various reasons including leakage, unloading to and reloading from transient storage compartments along the axial pathway (Fig.transport phloem) and xylem–phloem transfer (Atkins, ).Cited by: Phloem‐inspired artificial microfluidics systems such as that of Jensen et al.

We review new findings from diverse systems, including stems, seeds, flowers, and fruits. An important advance has been the identification of new transporters and facilitators Cited by: Transport path. Sugarcane and sweet sorghum may differ in their strategies for accumulating high levels of sucrose in their stems.

In maturing sugarcane stems, sucrose transport follows a predominantly symplastic pathway when moving from the phloem into the storage parenchyma cells (Figure Figure1A 1A; Lingle, ; Moore and Cosgrove, ; Rae et al., ; Patrick.
