TLDR
The xyloglucan fragment was found to inhibit gibberellic acid-induced elongation of etiolated pea epicotyls with maximum inhibition at concentrations ranging from 10 -11 to 10 -9 M.Abstract:
The biological activity of a cell wall-derived xyloglucan nonasaccharide (XG9) was investigated using a bioassay with entire pea epicotyls (Pisum sativum cv. Progress). The xyloglucan fragment was found to inhibit gibberellic acid-induced elongation of etiolated pea epicotyls with maximum inhibition at concentrations ranging from 10 -11 to 10 -9 M. Growth of etiolated epicotyls in the absence of exogenously applied GA 3 was also inhibited by XG9 in the same concentration rangeread more

Xyloglucan octasaccharide XXLGol derived from the seeds of hymenaea courbaril acts as a signaling molecule
Carem Vargas-Rechia,Fany Reicher,Maria Rita Sierakowski,Alain Heyraud,Hugues Driguez,Yvette Lienart +5 more
TL;DR: It was found that XXLGol is a signaling molecule, since it has the ability to induce, at nanomolar concentrations, a rapid increase in an alpha-l-fucosidase response in suspended cells or protoplasts of Rubus fruticosus L.

Effect of galactoglucomannan-derived oligosaccharides on elongation growth of pea and spruce stem segments stimulated by auxin
TL;DR: Galactoglucomannan-derived oligosaccharides isolated from the wood of poplar were shown to be inhibitors of the 2,4-dichlorophenoxyacetic acid-stimulated elongation growth of pea and spruce stem segments and did not exhibit toxicity even at high concentrations and during long-term bioassays.

Hormones, Signals and Target Cells in Plant Development
TL;DR: In this article, the authors discuss the mechanisms of target cell perception and response to specific signals and the phenomenon of hormonal crosstalk in higher plants, as well as the role of cell-to-cell signalling.
