Abstract
The primary wall and middle lamella control plant growth, abscission and ripening, so an understanding of wall assembly is important. Integration of new xyloglucan (xg), fundamental to wall assembly, is not understood. We will test the roles of interpolymeric transglycosylation (IPT), and hydrogen-bonding to cellulose, in xg integration. We will also test the role of IPT in wall restructuring. A major tool will be the feeding of 'substrate concentrations' of a heptasaccharide, XXXG, which competes with xg as acceptor substrate for transglycosylation. Complementary effects of cellulose synthesis inhibitors will be tested to probe the role of H-bonding. The effect of turgor pressure on these aspects of wall behaviour will be explored.
