Cell Wall-Related Proteins of Unknown Function: Missing Links in Plant Cell Wall Development

Introduction: plant cell wall proteins.

The cell wall and its underlying plasma membrane represent the dynamic interface between a plant cell and its environment, which includes neighboring cells. Biology texts commonly describe plant cell walls, but rarely acknowledge the existence and importance of cell wall proteins, making them the Rodney Dangerfields of plant biology. This set of multi-author reviews provides the reader with a c...

Structure and function of plant cell wall proteins.

Plant cell walls are amazingly complex amalgams of carbohydrates, proteins, lignin, water, and incrusting substances such as cutin, suberin, and certain inorganic compounds that vary among plant species, cell types, and even neighboring cells. Developmental events and exposure to any of a number of abiotic and biotic stresses further increase this compositional and structural variation. Moreove...

Isolation of plant cell wall proteins.

The quality of a proteomic analysis of a cell compartment strongly depends on the reliability of the isolation procedure for the cell compartment of interest. Plant cell walls possess specific drawbacks: (1) the lack of a surrounding membrane may result in the loss of cell wall proteins (CWP) during the isolation procedure; (2) polysaccharide networks of cellulose, hemicelluloses, and pectins f...

Plant cell wall dynamics and wall-related susceptibility in plant–pathogen interactions

The cell wall is a dynamic structure that often determines the outcome of the interactions between plants and pathogens. It is a barrier that pathogens need to breach to colonize the plant tissue. While fungal necrotrophs extensively destroy the integrity of the cell wall through the combined action of degrading enzymes, biotrophic fungi require a more localized and controlled degradation of th...
