Abstract
In etiolated leaves the occurrence of the enzymatic violaxanthin de-epoxidation to zeaxanthin is shown. The carotenoid transformation is provoked by the infiltration of whole leaves with ascorbate at pH 5 and is susceptible to DTT. Identification of the de-epoxidase activity is achieved by in vivo spectroscopy and pigment analysis (TLC).Keywords
