El mucílago de Arabidopsis como modelo para el estudio de componentes de la pared celular

Abstract

[ES] El estudio de las paredes celulares de plantas resulta difícil puesto que estas cuentan con multitud de componentes, entre los que destacamos la celulosa, hemicelulosas y pectinas, polisacáridos que interaccionan entre sí, formando una compleja y dinámica red. Por este motivo, en los últimos años se han buscado modelos simplificados de pared celular que faciliten su estudio, siendo el mucílago de Arabidopsis de los más empleados. El mucílago es una estructura gelatinosa compuesta principalmente por pectinas, que, en contacto con el agua, se libera de la cubierta de semillas maduras. Esta estructura se divide en una capa adherida a la superficie de la semilla, llamada mucílago adherido, y una parte soluble, denominada mucílago soluble. Está formado por una estructura única, especializada y accesible que presenta componentes similares a los de las paredes celulares primarias. Si a esto le sumamos el hecho de que la modificación de este gel no afecta a la viabilidad de la planta, obtenemos un modelo perfecto para la investigación sobre pared celular. Por todo ello, este trabajo es una revisión actualizada acerca de la estructura y composición del mucílago de semillas de Arabidopsis. Además, recoge las aplicaciones biotecnológicas que este posee. Todo ello remarca la importancia que presenta el mucílago para el hallazgo de nuevos genes implicados la síntesis y modificación de pectinas y otros componentes de la pared celular

[EN] The study of plant cell walls is difficult because they consist of a multitude of components, including cellulose, hemicelluloses and pectins, polysacharides which interact among them in order to form a complex and dynamic network. For this reason, in recent years many efforts have been made to find new cell wall simplified models that ease their study, with Arabidopsis mucilage being one of the most widely used. Mucilage is a gel-like structure composed mainly of pectins, which, in contact with water, extrudes from cells located in the mature seed coat. This structure is divided into a layer attached to the seed surface, called adherent mucilage, and a soluble part, called soluble mucilage. It consists of a unique, specialised and accessible structure with components similar to those of primary cell walls. Adding the fact that the modification of this gel does not affect the viability of the plant, we obtain a perfect model for cell wall research. Therefore, this work is an updated review of the structure and composition of Arabidopsis seed mucilage. In addition, it also includes the biotechnological applications it has. All this underlines the importance of mucilage for the discovery of new genes involved in the synthesis and modification of pectins and other cell wall components
