A METHOD FOR INCREASING THE SUGAR CONTENT OF A PLANT BODY AS COMPARED TO THE WILD STRAIN BY AFFECTING GLUTATHIONE LEVELS

摘要

Disclosed is a composition for producing a plant body having an improved sugar content, which comprises glutathione, a polynucleotide encoding a .gamma.-glutamylcysteine synthetase or a polynucleotide encoding a glutathione-binding plastid-type fructose-1,6-bisphosphate aldolase. Preferably, the composition comprises oxidized glutathione. It becomes possible to provide a composition for producing a plant having an improved sugar content conveniently.
