French. At least two main groups of glycoproteins can be distinguished in plant cell walls: extensins which are insoluble cell wall proteins; and soluble arabinogalactan proteins (AGPs) which have a high carbohydrate content such that protein content constitutes in some cases only 5 % of the glycoprotein weight. These two groups of proteins together with other cell wall proteins more or less glycosylated, such as proline-rich proteins (PRPs), hybrid PRP (HyPRPs) and expansins, are reviewed and compared with similar proteins present in other cell compartments. Different patterns of N- or O-glycosylation are analysed. In some cases, these cell wall proteins or proteins related to them present patterns of glycosylation that act as epitopes recognizable by IgE in allergie responses
