Deepening into the knowledge of maize cell wall plasticity: proteomic and biochemical approaches = Profundizando en el conocimiento de la pared celular de maíz: enfoques proteico y bioquímico

Abstract

Estudio de los polímeros estructurales de la pared celular en maíz.

El estudio de los componentes de la pared celular y de la interacción entre las diferentes redes estructurales nos permite ampliar nuestro conocimiento sobre la síntesis y ensamblaje de los componentes de la pared celular, así como de las bases moleculares de la plasticidad de la pared celular.= Plant cells are surrounded by a complex and dynamic compartment that defines the outer limits of the cell, the cell wall. This structure comprises three interconnected and independent structural networks (cellulose, hemicellulose and/or lignin) that constitute an essential scaffold to protect the cell and therefore play a crucial role in plant cell biology. Although widely regarded as a static compartment, the cell wall shows a remarkable plasticity in structure and composition. The study of cell wall components and the interaction among different structural networks allows us to gain knowledge about the synthesis, assembly of the cell wall components and molecular basis of cell wall plasticity.

Maize is an important crop worldwide due to its uses for food, forage and bioethanol production. For this reason, it is a suitable plant model for studying the cell wall plasticity in response to deficiencies in at least one of the three main structural networks of the cell wall. The overall aim of the present study is to elucidate the mechanisms associated with the structural plasticity of the cell wall, paying special attention to the biosynthesis of the different polysaccharides that form plant cell wall.
