Pectin: a critical component in cell-wall-mediated immunity

Contrary to the classical cell-wall model, pectin metabolism may play a crucial role in cell-wall integrity, detection of plant pathogens, and defense response. Here we discuss the evidence and propose a new metabolic and regulatory model linking pectin to cell-wall-mediated immunity, including ripening-associated dis-ease susceptibility in the tomato.

Contrary to the classical cell-wall model, the role of pectin metabolism in cell-wall integrity, pathogen detection, and defense response is discussed. A new metabolic and regulatory model linking pectin to cell-wall-mediated immunity, including disease susceptibility in tomato ripening, is proposed.
