Pectin in plant cell wall
WebNov 5, 2012 · Abstract. The methylesterification status of cell wall homogalacturonans, mediated through the action of pectin methylesterases (), influences the biophysical properties of plant cell walls such as elasticity and porosity, important parameters for cell elongation and water uptake.The completion of seed germination requires cell wall … WebJun 11, 2024 · Pectin, the concrete of the plant cell wall, is more flexible than cellulose, and it allows the cell wall to extend. Hemicellulose branches connect the cellulose beams and are all surrounded by bendable pectin strings, to form a strong network.
