Changes of trehalose content and trehalose-degrading activity during fruit-body formation and autolysis in Pleurotus sp.

Abstract We studied how the content and degrading activity of trehalose changed during fruit-body development and autolysis. During the process of autolysis, the trehalose content of whole fruit-bodies decreased sharply whereas the trehalose-degrading activity increased toward the inner region from the outer region of the pilei. Conversely, the trehalose content during autolysis decreased toward the inner region from the outer region of the pilei, and further decreased toward the bottom region from the top region of the stipes.
