Arabidopsis PECTIN METHYLESTERASEs contribute to immunity against Pseudomonas syringae.

Plant physiology - 1 Feb 2014

Abstract excerpt

Pectins, major components of dicot cell walls, are synthesized in a heavily methylesterified form in the Golgi and are partially deesterified by pectin methylesterases (PMEs) upon export to the cell wall. PME activity is important for the virulence of the necrotrophic fungal pathogen Botrytis cinerea. Here, the roles of Arabidopsis PMEs in pattern-triggered immunity and immune responses to the necrotrophic fungus...
