Abstract

Albersheims 1973 model of the Dicot primary wall proposed glycosidic bonds between xyloglucan (XyG) and pectin. The model lost favour owing to gaps in the original evidence, but we now have strong new evidence that 30 percent of XyG is indeed glycosidically linked to a pectin (RG-1) in rose cell cultures. We wish to extend these findings to explore the chemistry of XyG-RG-1 linkages, and their natural occurrences (cultures vs seedlings; wall vs middle lamella), site of formation (protoplast vs apoplast) and turnover. We will begin a search for the enzymes that form XyG-RG-I linkages. The goals are a balanced assessment of conflicting wall models and the knowledge needed to manipulate wall properties governing growth, ripening and abscission.
