The Induction of Ethylene Production from Pear Cell Culture by Cell Wall Fragments

Abstract

Macerase, a pectinase-containing enzyme mixture, was used to digest cell walls isolated from cultured pear cells. Following digestion, the reaction mixture was boiled to inactivate enzymes. Addition of soluble aliquots of the mixture to suspension cultures of pear cells led to a rapid and transient production of ethylene by the cells.
