composition after fractionation of cell wall material derived from 10 day old shoots of light grown seedlings.

Neutral sugars are expressed in mol%. Uronic acids and cellulose are expressed in [ µg/mg] fractionated cell wall material. Cellulose was measured after fractionation as release of hexoses from the pellet by Seaman hydrolysis. Significant alterations (n = 3; *: pNeutral sugars in mol %; significant alterations (p
