Sucrose: metabolite and signaling molecule

Wind, Julia, Smeekens, Sjef, Hanson, Johannes·2010·Phytochemistry

Abstract

Sucrose is a molecule that is synthesized only by oxygenic photosynthetic organisms. In plants, sucrose is synthesized in source tissues and then can be transported to sink tissues, where it is utilized or stored. Interestingly, sucrose is both a metabolite and a signaling molecule. Manipulating the rate of the synthesis, transport or degradation of sucrose affects plant growth, development and physiology. Altered sucrose levels changes the quantity of sucrose derived metabolites and sucrose-specific signaling. In this paper, these changes are summarized. Better understanding of sucrose metabolism and sucrose sensing systems in plants will lead to opportunities to adapt plant metabolism and growth.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Two pathways mediate sucrose cleavage in the cytosol; in one, sucrose is converted to glucose and fructose by invertase, and in the other, sucrose is converted to UDP-glucose and fructose by SuSy, and the UDP-glucose is then converted to glucose-1-phosphate by UGPase.

    “Two pathways mediate sucrose cleavage in the cytosol; in one, sucrose is converted to glucose and fructose by invertase, and in the other, sucrose is converted to UDP-glucose and fructose by SuSy (Li and Zhang, 2003; Wind et al., 2010), and the UDP-glucose is then converted to glucose-1-phosphate by UGPase, for use in subsequent reactions related to starch synthesis (Figure S2; Li and Zhang, 2003;”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
