The plant cell wall is a composite made of cellulose microfibrils associated with matrix components, among which the xylanfamily is the most represented. The review focuses on two types of biological models that are cellulose/glucuronoxylan (GX) comp

Summary The perennial and subterranean system of mandragora was studied by means of classical histology (specially using hydrochloric acid-phloroglucinol). The bulk of the hypertrophied and fleshy organ and its growth in girth results from the activi

SUMMARY Affinity methods (enzymes, lectins and antibodies used as specific probes) were applied in order to target cellulose and the major matrix components in cell walls of dicotyledons built up as helicoids. The probes were the enzyme cellobiohydro

The study was devoted to the microstructure of the thick walled cells of the endocarp of prune (Prunus domestica L.), cherry (Prunus cerasus L.), walnut (Juglons regia L.). The tissue is formed of closely associated cells showing a homogeneous develo

The object of the present paper is to complement the cytochemical detection of the polysacharides of the plant cell wall and of its precursors, taking benefit of two kinds of affinity methods: the enzyme-gold technique and immunocytochemistry. Cellob

The effect of an osmotic shock on the subsequent growth and cell wall texture was studied at 0, 1/2, 1, 2, 4 and 24 hours. Cells were taken at the beginning of their exponential growth from mung bean hypocotyl.

In fibres of wood, the classical S1 and S2 layers are connectedvia a transition zone where a helicoidal texture occurs. In order to understand the actual mechanism of cellulose microfibril rotation in this zone, the study of relationship between cell

The structure and breakdown of galactoxyloglucan (GXG)-rich cells was studied from cotyledons of Tamarindus indicus L. The depletion of GXG was followed at different levels: quantitative, histochemical and cytochemical. At the ultrastructural level t
