Sucrose is transported from sources (mature leaves) to sinks (importing tissues such as
roots, stems, fruits, and seeds) through the phloem tissues in veins. In many herbaceous …

In this postgenomic era, there is a specific need to assign function to orphan genes in order
to validate potential targets for drug therapy and to discover new biomarkers of disease …

Root high plasticity is an adaptation to its changing environment. Water deficit impairs
growth, leading to sugar accumulation in leaves, part of which could be available to roots via …

Coordination of development with the availability of nutrients, such as soluble sugars, may
help ensure an adequate supply of building materials and energy with which to carry out …

The phloem is a central component of the plant's complex vascular system that plays a vital
role in moving photoassimilates from sites of primary acquisition to the heterotrophic tissues …

Recent advances have provided new insights into how sucrose is moved from sites of
synthesis to sites of utilisation or storage in sink organs. Sucrose transporters play a central …

Recent developments have altered our view of molecular mechanisms that determine sink
strength, defined here as the capacity of non-photosynthetic structures to compete for import …

Sucrose is the principal product of photosynthesis used for the distribution of assimilated
carbon in plants. Transport mechanisms and efficiency influence photosynthetic productivity …

Structurally composed of the glucose homopolymers amylose and amylopectin, starch is the
main storage carbohydrate in vascular plants, and is synthesized in the plastids of both …
