Demethylesterification of cell wall pectins in Arabidopsis plays a role in seed germination.

Plant physiology - 1 Jan 2013

Abstract excerpt

The methylesterification status of cell wall homogalacturonans, mediated through the action of pectin methylesterases (PMEs), influences the biophysical properties of plant cell walls such as elasticity and porosity, important parameters for cell elongation and water uptake. The completion of see...
