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 …

▪ Abstract The primary effect of the response of plants to rising atmospheric CO2 (Ca) is to
increase resource use efficiency. Elevated Ca reduces stomatal conductance and …

▪ Abstract Plant gene responses to changing carbohydrate status can vary markedly. Some
genes are induced, some are repressed, and others are minimally affected. As in …

In addition to their essential roles as substrates in carbon and energy metabolism and in
polymer biosynthesis, sugars have important hormone-like functions as primary messengers …

Phytopathogen infection leads to changes in secondary metabolism based on the induction
of defence programmes as well as to changes in primary metabolism which affect growth …

The disaccharide sucrose and the cleavage products glucose and fructose are the central
molecules for carbohydrate translocation, metabolism and sensing in higher plants …

Sucrose (Suc) plays a central role in plant growth and development. It is a major end product
of photosynthesis and functions as a primary transport sugar and in some cases as a direct …

The mechanisms by which higher plants recognize and respond to sugars are largely
unknown. Here, we present evidence that the first enzyme in the hexose assimilation …

Leaf senescence is a hiphly‐controlled sequence of events comprising the final stage of
development. Cells remain viable during the process and new gene expression is required …
