Cell Wall Oligosaccharine Derivatives: Biological Activity and Participation in the Response of Plant Defense. Rev. mex. fitopatol [online]. 2010, vol.28, n.2, pp.144-155. ISSN 2007-8080.

The Fungi and plants cell wall is mainly composed of complex carbohydrates. Some fragments derived from these carbohydrates have an elicitor activity in plants, being known as oligosaccharine. The type of effect and specificity differ according to the oligosaccharine physicochemical characteristics and the plant species perceiving the signal. Understanding the action mechanisms, as well as all the signals regulating gene expressions and stimulating the synthesis of molecular effectors associated with the plant protective reactions could solve several problems present in vegetable crops, which are associated with resistance to diseases, yield and quality related aspects. Further studies are also needed to explore the feasibility of these models in agriculture, since they may represent an alternative to reduce the use of chemicals, and to analyze the potential of these molecules to improve yield and quality of agricultural products.

Keywords : elicitor; oligoglucanes; oligogalacturonide; chitooligosaccharides; receptors; fruit quality.
