Hemicellulose accumulation during process

It was shown that, in the maturing seeds, while the synthesis of reserve hemicellulose progresses in the endosperm, a large amount of a trehalose is formed, in addition to sucrose and umbelliferose.92 This trehalose disappears rapidly during the progress of the ripening process, and umbelliferose accumulates continuously. It was predicted that the trehalose may be present in most umbellifers however, the relationship of this disaccharide to the biosynthesis of umbelliferose, and the mechanism involved therein, are not known.
